For species descriptions and more details, visit each tree sale web page (click the sale name highlighted in blue). And don’t forget to order packs of evergreens for planting in mixed clumps and groves to provide winter shelter and summertime nesting sites for our local native birds. They’re only $12.00 for a bundle of 10.
It’s the most desirable block in town, not because the houses are any different from others built during the post-war years of the mid-twentieth century, but because the first owners of these domiciles had the good taste and foresight to plant long-lived trees on their lots, the majority of them native species. Pin Oak, Northern Red Oak, Yellow Poplar, Flowering Dogwood (Cornus florida), Eastern Red Cedar, Eastern White Pine, Eastern Hemlock, Norway Spruce, and American Holly dominate the landscape and create excellent habitat for birds and other wildlife. These 75-year-old plantings provide an abundance of shade in summer and thermal stability in winter, making it a “cool” place to live or take a stroll at any time of the year.

Cumberland County Conservation District is taking orders for Common Winterberry, the ideal small shrub for wet soil anywhere on your property. To get berries, you’ll need both males and females, so buy a bunch and plant them in a clump or scattered group.To live for a century or more like this towering giant, a Pin Oak needs to grow in well-drained soils with adequate moisture. These sturdy shade providers do well along streams and on low ground receiving clean runoff from hillsides, roofs, streets, and parking areas. As they age, Pin Oaks can fail to thrive and may become vulnerable to disease in locations where rainfall is not adequately infiltrated into the soil. Therefore, in drier areas such as raised ground or slopes, avoid the Pin Oak and select the more durable Northern Red Oak for planting. This year, Pin Oaks are available from the Cumberland and Lancaster County Conservation Districts, while Dauphin, Lancaster, Lebanon, and York Counties are taking orders for Northern Red Oaks.The Cumberland County Conservation District is again offering a “Showy Northeast Native Wildflower and Grass Mix” for seeding your own pollinator meadow or garden. It consists of more than twenty species including this perennial favorite, Purple Coneflower.

The Eastern Redbud is small tree native to our forest edges, particularly in areas of the Piedmont Province with Triassic geology (Furnace Hills, Conewago Hills, Gettysburg/Hammer Creek Formations, etc.) Also known as the Judas Tree, the redbud’s brilliant flowers are followed by heart-shaped leaves. As seen here, it is suitable for planting near houses and other buildings. Eastern Redbud seedlings are being offered through tree sales in Dauphin, Cumberland, and Lancaster Counties.
The Yellow Poplar, often called Tuliptree or Tulip Poplar for its showy flowers, is a sturdy, fast-growing deciduous tree native to forests throughout the Lower Susquehanna River Watershed. Its pole-straight growth habit in shady woodlands becomes more spreading and picturesque when the plant is grown as a specimen or shade tree in an urban or suburban setting. The Yellow Poplar can live for hundreds of years and is a host plant for the Eastern Tiger Swallowtail butterfly. It is available this year from the Lancaster County Conservation District.The American Sweetgum, also known as Sweet Gum, is a large, long-lived tree adorned with a mix of vibrant colors in autumn.Ever wonder where all the American Goldfinches and particularly the Pine Siskins go after passing through our region in fall? Well, many are headed to the lowland forests of the Atlantic Coastal Plain where they feed on an abundance of seeds contained in spiky American Sweetgum fruits. In the Piedmont and Ridge and Valley Provinces of the Lower Susquehanna River Watershed, American Sweetgum transplants can provide enough sustenance to sometimes lure our friendly finches into lingering through the winter.The American Sweetgum is a versatile tree. It can be planted on upland sites as well as in wet ground along streams, lakes, and rivers. In the beaver pond seen here it is the dominate tree species. This year, you can buy the American Sweetgum from the Lancaster County Conservation District.“Red-twig Dogwood” is a group of similar native shrubs that, in our region, includes Silky Dogwood and the more northerly Red-Osier Dogwood (Cornus sericea). Both have clusters of white flowers in spring and showy red twigs in winter. They are an excellent choice for wet soils. Landscapers often ruin these plants by shearing them off horizontally a foot or two from the ground each year. To produce flowers and fruit, and to preserve winter attractiveness, trim them during dormancy by removing three-year-old and older canes at ground level, letting younger growth untouched.“Red-twig Dogwoods” make ideal mass plantings for streamside buffers and remain showy through winter, even on a gloomy day. They not only mitigate nutrient and sediment pollution, they provide excellent food and cover for birds and other wildlife. Both Silky and Red-osier Dogwoods are available for sale through the Lancaster County Conservation District as part of their special multi-species offers, the former is included in its “Beauty Pack” and the latter in its “Wildlife Pack”. The similar Gray Dogwood (Cornus racemosa) is being offered for sale by the York County Conservation District.
The unique maroon flowers of the Common Pawpaw produce banana-like fruits in summer. These small native trees grow best in damp, well-drained soils on slopes along waterways, where they often form clonal understory patches. To get fruit, plant a small grove to increase the probability of pollination. The Common Pawpaw is a host plant for the Zebra Swallowtail butterfly. It is available through both the Lebanon and Lancaster County sales.The Eastern Red Cedar provides excellent food, cover, and nesting sites for numerous songbirds. Planted in clumps of dozens or groves of hundreds of trees, they can provide winter shelter for larger animals including deer and owls. The Eastern Red Cedar is being offered for purchase through both the Lebanon and Lancaster County Conservation Districts.Care to try your hand at raising some chestnuts? Lebanon County Conservation District has hybrid American Chestnut seedlings for sale.Lebanon County Conservation District is offering Common Winterberry and Eastern White Pine during their 2024 Tree and Plant Sale. Plant them both for striking color during the colder months. Eastern White Pine is also available from the Cumberland, Dauphin, Lancaster, and York County sales.
In addition to a selection of trees and shrubs, the Perry County Conservation District is again selling wildflower seed mixes for starting your own pollinator meadow or garden. For 2024, they have both a “Northeast Perennials and Annuals Mix” and a “Butterfly and Hummingbird Seed Mix” available. Give them a try so you can give up the mower!
Again this year, Perry County is offering bluebird nest boxes for sale. The price?—just $12.00.
Wait, what?,…twelve bucks,…that’s cheaper than renting!
The Buttonbush, a shrub of wet soils, produces a cosmic-looking flower. It grows well in wetlands, along streams, and in rain gardens. Buttonbush seedlings are for sale from both the York and Lancaster County Conservation Districts.
To get your deciduous trees like gums, maples, oaks, birches, and poplars off to a safe start, conservation district tree sales in Cumberland, Dauphin, Lancaster, and Perry Counties are offering protective tree shelters. Consider purchasing these plastic tubes and supporting stakes for each of your hardwoods, especially if you have hungry deer in your neighborhood.
Tree shelters protect newly transplanted seedlings from browsing deer, klutzy hikers, visually impaired mower operators, and other hazards.
There you have it. Be sure to check out each tree sale’s web page to find the selections you like, then get your order placed. The deadlines will be here before you know it and you wouldn’t want to miss values like these!
Since Tuesday’s snow storm, the susquehannawiildlife.net headquarters garden continues to bustle with bird activity.
Our Northern Mockingbird remains ever vigilant in its attempts to discourage American Robins and Eastern Bluebirds from feeding on the berry crop. Slowly, the latter species are winning the contest.A Carolina Chickadee carefully dissects a sunflower seed to snack on the nutritious kernel.This beauty shows us that yes, Red-bellied Woodpeckers do indeed have red bellies.Getting energized for a big move north, the robins keep on gulping berries.
Today, there arrived three species of birds we haven’t seen here since autumn. These birds are, at the very least, beginning to wander in search of food. Then too, these may be individuals creeping slowly north to secure an advantage over later migrants by being the first to establish territories on the most favorable nesting grounds.
This Song Sparrow is the first we’ve seen in the garden since sometime last fall. Is it working its way north or did it just come to town in search of food?Northern Flickers regularly spend the winter in small numbers in the Lower Susquehanna River Watershed. This is the first one we’ve had visit the garden since late last autumn.Fish Crows, seen here feeding on the fruits adorning an Eastern Red Cedar, have returned after being absent in our neighborhood since November. In coming weeks, both they and the more numerous American Crows that remained through winter will begin constructing nests in nearby trees.
They say the early bird gets the worm. More importantly, it gets the most favorable nesting spot. What does the early birder get? He or she gets out of the house and enjoys the action as winter dissolves into the miracle of spring. Do make time to go afield and marvel a bit, won’t you? See you there!
In mid-February each year, large numbers of American Robins descend upon the susquehannawildlife.net headquarters garden to feast on the ripe fruits that adorn several species of our native shrubs and trees. This morning’s wet snowfall provided the needed motivation for these birds and others to make today the big day for the annual feeding frenzy.
Early this morning, branches and limbs in the headquarters garden were loaded with clinging snow and more than one hundred American Robins.To have first grabs at suitable nesting sites, early American Robins are currently beginning to edge their way north. Spring migration is underway.The fruits of Common Winterberry are always a favorite of visiting robins.After selfishly guarding the garden’s berries through the entire season, our Northern Mockingbird finds chasing more than one hundred robins away from its food supply an impossible task.This and other visiting robins will strip the winterberry, cedar, American Holly, and other fruit-producing shrubs and trees within a day or two. To survive what remains of the season, our resident mockingbird will have to look elsewhere for provisions.Another American Robin devouring winterberry fruit.In addition to robins, there were, of course, other guests in the garden refuge on this snowy day.This Red-bellied Woodpecker tries to make sense of all the commotion.A pair of Carolina Chickadees established a family in the garden during the spring of 2023.

This linear grove of mature trees, many of them nearly one hundred years old, is a planting of native White Oaks (Quercus alba) and Swamp White Oaks (Quercus bicolor).
Imagine the benefit of trees like this along that section of stream you’re mowing or grazing right now. The Swamp White Oak in particular thrives in wet soils and is available now for just a couple of bucks per tree from several of the lower Susquehanna’s County Conservation District Tree Sales. These and other trees and shrubs planted along creeks and rivers to create a riparian buffer help reduce sediment and nutrient pollution. In addition, these vegetated borders protect against soil erosion, they provide shade to otherwise sun-scorched waters, and they provide essential wildlife habitat. What’s not to love?
Autumn leaf of a Swamp White Oak
The following native species make great companions for Swamp White Oaks in a lowland setting and are available at bargain prices from one or more of the County Conservation District Tree Sales now underway…
The Red Maple is an ideal tree for a stream buffer project. They do so well that you should limit them to 10% or less of the plants in your project so that they don’t overwhelm slower-growing species.The River Birch (Betula nigra) is a multi-trunked tree of lowlands. Large specimens with arching trunks help shade waterways and provide a source of falling insects for surface-feeding fish. Its peeling bark is a distinctive feature.The Common Winterberry with its showy red winter-time fruit is a slow-growing shrub of wet soils. Only female specimens of this deciduous holly produce berries, so you need to plant a bunch to make sure you have both genders for successful pollination.An American Robin feeding on Common Winterberry.Common Spicebush is a shrub of moist lowland soils. It is the host plant for the Spicebush Swallowtail butterfly and produces small red berries for birds and other wildlife. Plant it widely among taller trees to provide native vegetation in the understory of your forest.Common Spicebush foliage and berries in the shade beneath a canopy of tall trees.The Common Pawpaw a small shade-loving tree of the forest understory.Common Pawpaw is a colony-forming small tree which produces a fleshy fruit. It is the host plant for the caterpillars of the Zebra Swallowtail.The Buttonbush is a shrub of wet soils. It produces a round flower cluster, followed by this globular seed cluster.And don’t forget the Eastern Sycamore, the giant of the lowlands. At maturity, the white-and-tan-colored bark on massive specimens makes them a spectacular sight along stream courses and river shores. Birds ranging from owls, eagles, and herons to smaller species including the Yellow-throated Warbler rely upon them for nesting sites.Yellow-crowned Night Herons, an endangered species in Pennsylvania, nesting in an Eastern Sycamore.
So don’t mow, do something positive and plant a buffer!

The annual arrival of hoards of American Robins to devour the fruits found on the various berry-producing shrubs and trees in the garden at susquehannawildlife.net headquarters happened to coincide with this morning’s bitter cold temperatures. Here are photos of some of those hungry robins—plus shots of the handful of other songbirds that joined them for a frosty feeding frenzy.

We don’t have a resident groundhog at susquehannawildlife.net headquarters, but the arrival of an American Robin to begin cleaning the abundance of berries from our holly trees and shrubs gives us the idea that spring is just around the corner. We could hardly be happier.
From a lookout atop an Eastern Hemlock, a Northern Mockingbird maintains a vigil over a garden full of berry-producing plants. To assure their survival during cold weather, these bold birds will vigorously defend winter food supplies on hollies, viburnums, poison-ivy, bittersweet, and other fruit-producing trees, shrubs, and vines, often swooping in to startle and flush birds and other animals that approach its stores too closely.
You probably know that fall is an excellent time for planting. Roots continue to grow in the warm soil even after the air becomes cool and leaves change color, setting the stage for your new trees and shrubs to sport splendid foliage and flowers in spring.
But did you know that autumn can be the best time to visit your local nursery/garden center to select the native trees and shrubs that produce berries for attracting and feeding overwintering birds and other wildlife? Here are three of our favorites. Each is looking its best from now through at least the first half of winter.
American Holly is a favorite small evergreen tree for winter beauty in the landscape. The showy red berries are produced only on female plants, so you’ll need to select at least one of each gender to grow fruit. They do best in acidic soils, responding well to a mulching of plenty of dead leaves each fall.American Robins eating American Holly berries in February.Common Winterberry is a slow-growing deciduous shrub and a member of the holly family; you’ll need both a male and a female plant to get a crop of berries. It just so happens that fall is the best time to visit the nursery for selecting a female that’s a good fruit producer. Winterberry is at its best under full sun in moist, acidic soils. These plants are very happy to receive the water from your downspouts and a mulching from the leaves in your garden.An American Robin feeds on Common Winterberry on a snowy February evening.American Beautyberry (Callicarpa americana) is a low-growing arching deciduous shrub of sunny locations in various well-drained soils. It is a plant of the southern United States that, given current temperature trends, will thrive in the Lower Susquehanna River Watershed, particularly on south-facing slopes. And yes, it does well in mass plantings on embankments.The fruits of American Beautyberry may be the most colorful of any native species.
There’s still time to get the shovel dirty, so visit your local native plant dealer this week and invest in some fruit-producing trees and shrubs. Fall is also a good time to plant pines, spruces, and hemlocks. Who knows, you might just get a good end-of-season deal.
When planted in mixed clumps, conifers like these White Pines, Norway Spruces, and Eastern Red Cedar provide excellent winter food and cover for birds and other wildlife.
Despite being located in an urbanized downtown setting, blustery weather in recent days has inspired a wonderful variety of small birds to visit the garden here at the susquehannawildlife.net headquarters to feed and refresh. For those among you who may enjoy an opportunity to see an interesting variety of native birds living around your place, we’ve assembled a list of our five favorite foods for wild birds.
American Goldfinches in drab winter (basic) plumage visit the trickle of water entering the headquarters pond to bathe and drink. In addition to offering the foods animals need to survive, a source of clean water is an excellent way to attract wildlife to your property.
The selections on our list are foods that provide supplemental nutrition and/or energy for indigenous species, mostly songbirds, without sustaining your neighborhood’s non-native European Starlings and House Sparrows, mooching Eastern Gray Squirrels, or flock of ecologically destructive hand-fed waterfowl. We’ve included foods that aren’t necessarily the cheapest but are instead those that are the best value when offered properly.
Bread, “bargain” seed mixes, and cracked corn can attract and sustain large numbers of House Sparrows and European Starlings. Both are non-native species that compete mercilessly with indigenous birds including bluebirds for food and nesting sites. Though found favorable for feeding Northern Cardinals without attracting squirrels, the expensive safflower seed seen here is another favorite of these aggressive House Sparrows. Ever wasteful, they “shovel” seed out of feeders while searching for the prime morsels from which they can easily remove the hulls. Trying not to feed them is an ongoing challenge, so we don’t offer these aforementioned foods to our avian guests.
Number 5
Raw Beef Suet
In addition to rendered beef suet, manufactured suet cakes usually contain seeds, cracked corn, peanuts, and other ingredients that attract European Starlings, House Sparrows, and squirrels to the feeder, often excluding woodpeckers and other native species from the fare. Instead, we provide raw beef suet.
Because it is unrendered and can turn rancid, raw beef suet is strictly a food to be offered in cold weather. It is a favorite of woodpeckers, nuthatches, and many other species. Ask for it at your local meat counter, where it is generally inexpensive.
Raw beef suet is fat removed from areas surrounding the kidneys on a beef steer. To avoid spoiling, offer it only in the winter months, particularly if birds are slow to consume the amount placed for them. If temperatures are above freezing, it’s important to replace uneaten food frequently. The piece seen here on the left was stored in the freezer for almost a year while the rancid piece to the right was stored in a refrigerator at about 40 degrees Fahrenheit for just two months. You can render raw beef suet and make your own cakes by melting it down and pouring it into a form such as cupcake tin. But do it outdoors or you’ll be living alone for a while.A female Downy Woodpecker feeds on raw beef suet stuffed into holes drilled into a vertically hanging log. Because they can’t be cleaned, log feeders should be discarded after one season. Wire cage feeders though, can usually be scrubbed, disinfected, dried, and reused.Pesky European Starlings might visit a raw beef suet feeder but won’t usually linger unless other foods to their liking are available nearby.This male Downy Woodpecker has no trouble feeding on raw beef suet packed into holes drilled into the underside of this horizontally hanging log. Starlings don’t particularly care to feed this way.Unusual visitors like a Brown Creeper are more likely to stop by at a suet feeder when it isn’t crowded by raucous starlings, House Sparrows, and squirrels. This one surprised us just this morning.Below the feeders, scraps of suet that fall to the ground are readily picked up, usually by ground-feeding birds. In this instance, a male Eastern Bluebird saw a chunk break loose and pounced on it with haste.
Number 4
Niger (“Thistle”) Seed
Niger seed, also known as nyjer or nyger, is derived from the sunflower-like plant Guizotia abyssinica, a native of Ethiopia. By the pound, niger seed is usually the most expensive of the bird seeds regularly sold in retail outlets. Nevertheless, it is a good value when offered in a tube or wire mesh feeder that prevents House Sparrows and other species from quickly “shoveling” it to the ground. European starlings and squirrels don’t bother with niger seed at all.
Niger seed must be kept dry. Mold will quickly make niger seed inedible if it gets wet, so avoid using “thistle socks” as feeders. A dome or other protective covering above a tube or wire mesh feeder reduces the frequency with which feeders must be cleaned and moist seed discarded. Remember, keep it fresh and keep it dry!
Niger (“thistle”) seed is very small, so it is offered in specialized feeders to prevent seed from spilling out of oversize holes as waste.An American Goldfinch in winter plumage feeding on niger seed from a wire mesh feeder. By April, goldfinches are molting into spectacular breeding feathers. Niger seed can be offered year-round to keep them visiting your garden while they are at maximum magnificence.American Goldfinches in August. This tube feeder is designed specifically for goldfinches, birds that have no difficulty hanging upside down to grab niger seed from small feeding ports.During invasion years, visiting Pine Siskins favor niger seed at feeding stations.Like goldfinches, Pine Siskins are quite comfortable feeding upside down on specialized tubes with perches positioned above the seed ports. Seeds dropped to the ground are readily picked up by ground-feeding birds including Mourning Doves and Dark-eyed Juncos. Periodically, uneaten niger seed should be swept up and discarded.
Number 3
Striped Sunflower Seed
Striped sunflower seed, also known as grey-striped sunflower seed, is harvested from a cultivar of the Common Sunflower (Helianthus annuus), the same tall garden plant with a massive bloom that you grew as a kid. The Common Sunflower is indigenous to areas west of the Mississippi River and its seeds are readily eaten by many native species of birds including jays, finches, and grosbeaks. The husks are harder to crack than those of black oil sunflower seed, so House Sparrows consume less, particularly when it is offered in a feeder that prevents “shoveling”. For obvious reasons, a squirrel-proof or squirrel-resistant feeder should be used for striped sunflower seed.
Striped sunflower seed.A male House Finch and a Carolina Chickadee pluck striped sunflower seeds from a squirrel-resistant powder-coated metal-mesh tube feeder.An American Goldfinch in winter plumage finds striped sunflower seeds irresistible, even with niger seed being offered in an adjacent feeder.A Tufted Titmouse visits a feeder stocked with striped sunflower seeds.Northern Cardinals readily feed on striped sunflower seeds, especially those that fall from our metal-mesh tube feeders.An Eastern Gray Squirrel (Sciurus carolinensis) has no choice but to be satisfied with striped sunflower seeds that spill from our wire-mesh tube feeders.
Number 2
Mealworms
Mealworms are the commercially produced larvae of the beetle Tenebrio molitor. Dried or live mealworms are a marvelous supplement to the diets of numerous birds that might not otherwise visit your garden. Woodpeckers, titmice, wrens, mockingbirds, warblers, and bluebirds are among the species savoring protein-rich mealworms. The trick is to offer them without European Starlings noticing or having access to them because European Starlings you see, go crazy over a meal of mealworms.
Dried mealworms can be offered in a cup or on a tray feeder. Live mealworms need to be contained in a steep-sided dish, so they don’t crawl away. Unless you’re really lucky, you’ll probably have to place your serving vessel of mealworms inside some type of enclosure to exclude European Starlings.A male Eastern Bluebird tossing and grabbing a dried mealworm.A female Eastern Bluebird with a dried mealworm.A pair of Eastern Bluebirds. The value of mealworms is self-evident: you get to have bluebirds around.
To foil European Starlings, we assembled this homemade mealworm feeder from miscellaneous parts. The bluebirds took right to it.It frustrates the starlings enough to discourage them from sticking around for long.If you’re offering dried mealworms, a source of clean water must be available nearby so that the bluebirds and other guests at your feeder don’t become dehydrated.
Number 1
Food-producing Native Shrubs and Trees
The best value for feeding birds and other wildlife in your garden is to plant food-producing native plants, particularly shrubs and trees. After an initial investment, they can provide food, cover, and roosting sites year after year. In addition, you’ll have a more complete food chain on a property populated by native plants and all the associated life forms they support (insects, spiders, etc.).
In your garden, a Northern Mockingbird may defend a food supply like these Common Winterberry fruits as its sole means of sustenance for an entire winter season. Having an abundance of plantings assures that in your cache there’s plenty to eat for this and other species.The American Goldfinches currently spending the winter at our headquarters are visiting the feeders for niger and striped sunflower seeds, but the bulk of their diet consists of tiny seeds from the cones on our Eastern Hemlock trees. At night, birds obtain shelter from the weather by roosting in this clump of evergreens.While the Eastern Bluebirds visiting the susquehannawildlife.net headquarters are fond of mealworms, the bulk of their diet here consists of these Common Winterberry fruits and the berries on our American Holly trees.Cedar Waxwings are readily attracted to red berries including Common Winterberry fruit.Migrating American Robins visit the headquarters garden in late winter each year to devour berries before continuing their journey to the north.
Your local County Conservation District is having its annual spring tree sale soon. They have a wide selection to choose from each year and the plants are inexpensive. They offer everything from evergreens and oaks to grasses and flowers. You can afford to scrap the lawn and revegetate your whole property at these prices—no kidding, we did it. You need to preorder for pickup in the spring. To order, check their websites now or give them a call. These food-producing native shrubs and trees are by far the best bird feeding value that you’re likely to find, so don’t let this year’s sales pass you by!
On a snowy winter day, it sure is nice to see some new visitors at a backyard feeding station. Here at the susquehannawildlife.net headquarters, American Robins have arrived to partake of the offerings.
American Robins feed on peanut hearts and chopped apples.
For this flock of robins, which numbered in excess of 150 individuals, the contents of this tray were a mere garnish to the meal that would sustain them through 72 hours of stormy weather. The main course was the supply of ripe berries on shrubs and trees in the headquarters garden.
Their first choice—the bright red fruits of the Common Winterberry.

Wouldn’t it be great to see these colorful birds in your garden each winter? You can, you know. Won’t you consider adding plantings of native trees and shrubs to your property this spring? Here at the susquehannawildlife.com headquarters we mow no lawn; the lawn is gone. Mixing evergreens and fruit-producing shrubs with native warm-season grasses and flowering plants has created a wildlife oasis absent of that dirty habit of mowing and blowing.
You can find many of the plants seen here at your local garden center. Take a chunk out of your lawn by paying them a visit this spring.
Want a great deal? Many of the County Conservation District offices in the lower Susquehanna region are having their annual spring tree sales right now. Over the years, we obtained many of our evergreens and berry-producing shrubs from these sales for less than two dollars each. At that price you can blanket that stream bank or wet spot in the yard with winterberries and mow it no more! The deadlines for orders are quickly approaching, so act today—literally, act today. Visit your County Conservation District’s website for details including selections, prices, order deadlines, and pickup dates and locations.
Evergreens like this Eastern Hemlock (Tsuga canadensis) are essential to the survival of many species of wintering birds. Plant evergreens in clumps, the bigger the better, to provide birds with thermal protection against the cold winds of winter nights.County Conservation District Tree Sales offer bare root evergreens like this Eastern White Pine (Pinus strobus) in packs of five or ten. Buy a bunch. Spend this year’s lawn treatment money on them. Then, get them planted immediately after pickup in the spring and in a few years you’ll have a nice grove of evergreens for wildlife habitat, a wind break, or a privacy screen.Groves of mixed evergreens among deciduous woods, grasslands, farmlands, or suburbs are ideal cover for wintering wildlife. These stands attract many species of migrating and nesting birds as well. Seen here, left to right, are Eastern White Pine, Norway Spruce (Picea abies), and Eastern Red Cedar. Though not a native species, the Norway Spruce is frequently used for conservation and ornamental plantings in the northeastern United States due to its appealing attributes and lack of invasive characteristics.Feeding wildlife is great fun. But remember, if you’re running a hotel for animals, you’ve got to offer more than an after-dinner mint to your tired and hungry guests. Let’s get planting!

Thoughts of October in the Lower Susquehanna River Watershed bring to mind scenes of brilliant fall foliage adorning wooded hillsides and stream courses, frosty mornings bringing an end to the growing season, and geese and other birds flying south for the winter.
The autumn migration of birds spans a period equaling nearly half the calendar year. Shorebirds and Neotropical perching birds begin moving through as early as late July, just as daylight hours begin decreasing during the weeks following their peak at summer solstice in late June. During the darkest days of the year, those surrounding winter solstice in late December, the last of the southbound migrants, including some hawks, eagles, waterfowl, and gulls, may still be on the move.
The Rough-legged Hawk (Buteo lagopus), a rodent-eating raptor of tundra, grassland, and marsh, is rare as a migrant and winter resident in the lower Susquehanna valley. It may arrive as late as January, if at all.
During October, there is a distinct change in the list of species an observer might find migrating through the lower Susquehanna valley. Reduced hours of daylight and plunges in temperatures—particularly frost and freeze events—impact the food sources available to birds. It is during October that we say goodbye to the Neotropical migrants and hello to those more hardy species that spend their winters in temperate climates like ours.
During several of the first days of October, two hundred Chimney Swifts remained in this roost until temperatures warmed from the low forties at daybreak to the upper fifties at mid-morning; then, at last, the flock ventured out in search of flying insects. When a population of birds loses its food supply or is unable to access it, that population must relocate or perish. Like other insectivorous birds, these swifts must move to warmer climes to be assured a sustained supply of the flying bugs they need to survive. Due to their specialized food source, they can be considered “specialist” feeders in comparison to species with more varied diets, the “generalists”. After returning to this chimney every evening for nearly two months, the swifts departed this roost on October 5 and did not return.A Northern Parula lingers as an October migrant along the Susquehanna. This and other specialist feeders that survive almost entirely on insects found in the forest canopy are largely south of the Susquehanna watershed by the second week of October.The Blackpoll Warbler is among the last of the insectivorous Neotropical warblers to pass through the riparian forests of the lower Susquehanna valley each fall. Through at least mid-October, it is regularly seen searching for crawling insects and larvae among the foliage and bark of Northern Hackberry (Celtis occidentalis) trees near Conewago Falls. Most other warblers, particularly those that feed largely upon flying insects, are, by then, already gone.The Blue-headed Vireo, another insectivore, is the last of the vireo species to pass through the valley. They linger only as long as there are leaves on the trees in which they feed.Brown Creepers begin arriving in early October. They are specialist feeders, well-adapted to finding insect larvae and other invertebrates among the ridges and peeling bark of trees like this hackberry, even through the winter months.Ruby-crowned Kinglets can be abundant migrants in October. They will often behave like cute little flycatchers, but quickly transition to picking insects and other invertebrates from foliage and bark as the weather turns frosty. Some may spend the winter here, particularly in the vicinity of stands of pines, which provide cover and some thermal protection during storms and bitter cold.Beginning in early October, Golden-crowned Kinglets can be seen searching the forest wood for tiny invertebrates. They are the most commonly encountered kinglet in winter.The Yellow-bellied Sapsucker, a woodpecker, is an October migrant that specializes in attracting small insects to tiny seeps of sap it creates by punching horizontal rows of shallow holes through the tree bark. Some remain for winter.The Yellow-rumped Warbler arrives in force during October. It is the most likely of the warblers to be found here in winter. Yellow-rumped Warblers are generalists, feeding upon insects during the warmer months, but able to survive on berries and other foods in late fall and winter. Wild foods like these Poison Ivy berries are crucial for the survival of this and many other generalists.American Robins are most familiar as hunters of earthworms on the suburban lawn, but they are generalist feeders that rely upon fruits like these Eastern Red Cedar (Juniperus virginiana) berries during their southbound migration in late October and early November each year. Robins remain for the winter in areas of the lower Susquehanna valley with ample berries for food and groves of mature pines for roosting.Like other brown woodland thrushes, the Hermit Thrush (Catharus guttatus) is commonly seen scratching through organic matter on the moist forest floor in search of invertebrates. Unlike the other species, it is a cold-hardy generalist feeder, often seen eating berries during the southbound October migration. Small numbers of Hermit Thrushes spend the winter in the lower Susquehanna valley, particularly in habitats with a mix of wild foods.Due to their feeding behavior, Cedar Waxwings can easily be mistaken for flycatchers during the nesting season, but by October they’ve transitioned to voracious consumers of small wild fruits. During the remainder of the year, flocks of waxwings wander widely in search of foods like this Fox Grape (Vitis labrusca). An abundance of cedar, holly, Poison Ivy, hackberry, bittersweet , hawthorn, wild grape, and other berries is essential to their survival during the colder months.Red-breasted Nuthatches have moved south in large numbers during the fall of 2020. They were particularly common in the lower Susquehanna region during mid-October. Red-breasted Nuthatches can feed on invertebrates during warm weather, but get forced south from Canada in droves when the cone crops on coniferous trees fail to provide an adequate supply of seeds for the colder fall and winter seasons. In the absence of wild foods, these generalists will visit feeding stations stocked with suet and other provisions.Purple Finches (Haemorhous purpureus) were unusually common as October migrants in 2020. They are often considered seed eaters during cold weather, but will readily consume small fruits like these berries on an invasive Mile-a-minute Weed (Persicaria perfoliata) vine. Purple Finches are quite fond of sunflower seeds at feeding stations, but often shy away if aggressive House Sparrows or House Finches are present.
The need for food and cover is critical for the survival of wildlife during the colder months. If you are a property steward, think about providing places for wildlife in the landscape. Mow less. Plant trees, particularly evergreens. Thickets are good—plant or protect fruit-bearing vines and shrubs, and allow herbaceous native plants to flower and produce seed. And if you’re putting out provisions for songbirds, keep the feeders clean. Remember, even small yards and gardens can provide a life-saving oasis for migrating and wintering birds. With a larger parcel of land, you can do even more.
GOT BERRIES? Common Winterbery (Ilex verticillata) is a native deciduous holly that looks its best in the winter, especially with snow on the ground. It’s slow-growing, and never needs pruning. Birds including bluebirds love the berries and you can plant it in wet ground, even along a stream, in a stormwater basin, or in a rain garden where your downspouts discharge. Because it’s a holly, you’ll need to plant a male and a female to get the berries. Full sun produces the best crop. Fall is a great time to plant, and many garden centers that sell holiday greenery still have winterberry shrubs for sale in November and December. Put a clump of these beauties in your landscape. Gorgeous!
