Today’s Golden Eagle Flight
Here are several of the Golden Eagles seen migrating in this morning’s stiff north-northwest wind along Second Mountain in Lebanon County, Pennsylvania.
To learn more about determining the age of a Golden Eagle on the wing, click the “Golden Eagle Aging Chart” tab at the top of this page, then get to a hawk watch and have a look.
Black-capped Chickadee Invasion
Our cute lovable chickadees are resident birds, remaining in the same general area throughout the year, often throughout their lives. In the Mid-Atlantic States, there are two species. The tiny Carolina Chickadee is at the northern limit of its geographic range in the Piedmont Province of southcentral Pennsylvania. The slightly larger Black-capped Chickadee is a year-round resident mostly to the north of the Lower Susquehanna River Watershed. Within the Susquehanna basin, an intergrade zone of the two species occurs in the mountains and bottomlands of the southern portion of the Ridge and Valley Province just to the north of the Pennsylvania cities of Carlisle, Harrisburg, and Lebanon. The range of the Carolina Chickadee, as well as the hybrid zone, has gradually crept north during the last fifty years—as much as twenty or thirty miles—while the range of the pure-bred Black-capped Chickadee has simultaneously withdrawn almost entirely from the lower Susquehanna, particularly in the valleys.
Every few years, presumably when their numbers are too great for the sustenance available from the wild food crop in their home range, Black-capped Chickadees invade the more southerly range of both Carolina Chickadees and the hybrids in the intergrade zone. This appears to be one of those years. Black-capped Chickadees are working their way south and showing up at feeding stations stocked with sunflower seeds, safflower seeds, and/or peanuts—sometimes in flocks numbering five to ten birds or more.
Let’s take a closer look at the two species…
Not only is now a good time to carefully check the chickadees you see, but it’s an opportune time to watch for other invaders from the north, specifically the “winter fiches” including Pine Siskins, Evening Grosbeaks, Purple Finches, Red Crossbills (Loxia curvirostra), and White-winged Crossbills (Loxia leucoptera). During recent weeks, each of these species has been reported by observers at hawk-counting stations on local ridgetops, an indication that they too are experiencing inadequate food resources in their home ranges.
So, as winter approaches, you’ll want to keep an eye on those feeders—and don’t forget to keep an ear on the pines and hemlocks. The rewards could be many!
Northwest Winds in November Bring Big Birds
With colder temperatures arriving on gusty northwest winds, the next couple of days will be ideal for seeing migrating birds of prey along the ridges of the Lower Susquehanna River Watershed. It’s still peak time for movements of four of our largest species: Red-shouldered Hawk, Red-tailed Hawk, Bald Eagle, and Golden Eagle—so let’s grab our binoculars and have a look!
Be certain to click the “Hawkwatcher’s Helper” tab at the top of this page to select a lookout for observing and enjoying the passage of these spectacular late-season raptors. To improve your chances of seeing a Golden Eagle, visit a counting station in the Ridge and Valley Province, but do bundle up—it’s cold on those mountaintops.

Nocturnal Migrants in Moonlight
Happening right now, in the bright moonlight on a crisp autumn night, there is a massive movement of nocturnally migrating birds indicated on National Weather Service Radar from State College, Pennsylvania. Notice the dense wave crossing the lower Susquehanna River watershed from northeast to southwest. The coming morning may reveal plenty of new arrivals after daybreak. Look for robins, native sparrows, etc.

Select Your Berry-producing Plants Now
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.
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.

Something in the Air Tonight
There’s something in the air tonight—and it’s more than just a cool comfortable breeze.
It’s a major nocturnal movement of southbound Neotropical birds. At daybreak, expect a fallout of migrants, particularly songbirds, in forests and thickets throughout the region. Warblers, vireos, flycatchers, thrushes, Scarlet Tanagers, and Rose-breasted Grosbeaks pass through in mid-September each year, so be on the lookout!

Two Feeders Are Better Than One
Over the coming six weeks or more, Ruby-throated Hummingbirds will be feeding throughout the daylight hours to fuel their long migration to the tropics for winter. With plenty of adult and juvenile birds around, it’s the best time of year to get a better look at them by putting up a feeder.
You may already know the basics—hang the feeder near flower beds if you have them, keep it filled with a mixture of one part sugar to four parts water, and fill the little ant trap with fresh water. And you may know too, that to provide for the birds’ safety you should avoid hanging your feeder near plate glass windows and you should keep it high enough to avoid ambushes by any predators which may be hiding below.
Now here’s a hummingbird feeding basic (a bird feeding basic really) that you may not have considered. For every hummingbird feeder you intend to have filled and hanging in your garden, have a second one cleaned and air-drying to replace it when it’s time to refill. Why? Sugar water, like bird seed when it gets wet, is an excellent media for growing bacteria, molds, and other little beasties that can make birds (and people) sick. In the summer heat, these microorganisms grow much faster than they would in the wintertime, so diligence is necessary. Regularly, on a daily basis ideally, each feeder in your garden should be taken down and replaced with a clean, dry feeder filled with fresh sugar water mixture. The cleaning process should include dumping of the feeder’s contents followed by a thorough scrubbing with soapy water to remove any food residues that, if left remaining, can provide nourishment for growing bacteria. Next, the feeder should be rinsed with clean water to wash away soap and debris. You can sanitize the feeder if you wish, but it is more important to allow it to air-dry until its next use. Depriving mold, bacteria, and other microbes of moisture is a critical step in the process of eliminating them as a health hazard.
A Note of Caution: To avoid cross contaminating the utensils and space you use for preparing and serving meals, it’s important to have a separate work area with brushes, buckets, and other equipment dedicated only to bird feeder cleaning and drying.
So, let’s review. If you’re going to have a hummingbird feeder filled with nectar hanging in your garden, you need a second one—clean, dry, and ready to replace it.
If you’d like to attract more than one hummingbird at a time to your garden, you may want to place a second feeder where the territorial little bird claiming the first as its own can’t see it. Then you’ll need four feeders—two hanging in the garden and two that are clean, dry, and ready to be filled with fresh sugar water to use as replacements.
If you’re in a rural area with good habitat, you may have four or more feeders around your refuge. You’ll need a replacement feeder for each.
Remember, keep your feeders clean and filled with fresh nectar and you’ll be all set to enjoy the Ruby-throated Hummingbirds of late summer. Then watch closely for the cold-hardy western species that visit the Lower Susquehanna River Watershed beginning in October. The occurrence of at least one of these rarities in the Lower Susquehanna River Watershed each autumn is now something of a regular event.

Monarch an Endangered Species: What You Can Do Right Now
This month, the International Union for Conservation of Nature (I.U.C.N.) added the Migratory Monarch Butterfly (Danaus plexippus plexippus) to its “Red List of Threatened Species”, classifying it as endangered. Perhaps there is no better time than the present to have a look at the virtues of replacing areas of mowed and manicured grass with a wildflower garden or meadow that provides essential breeding and feeding habitat for Monarchs and hundreds of other species of animals.
If you’re not quite sure about finally breaking the ties that bind you to the cult of lawn manicuring, then compare the attributes of a parcel maintained as mowed grass with those of a space planted as a wildflower garden or meadow. In our example we’ve mixed native warm season grasses with the wildflowers and thrown in a couple of Eastern Red Cedars to create a more authentic early successional habitat.
Still not ready to take the leap. Think about this: once established, the wildflower planting can be maintained without the use of herbicides or insecticides. There’ll be no pesticide residues leaching into the soil or running off during downpours. Yes friends, it doesn’t matter whether you’re using a private well or a community system, a wildflower meadow is an asset to your water supply. Not only is it free of man-made chemicals, but it also provides stormwater retention to recharge the aquifer by holding precipitation on site and guiding it into the ground. Mowed grass on the other hand, particularly when situated on steep slopes or when the ground is frozen or dry, does little to stop or slow the sheet runoff that floods and pollutes streams during heavy rains.
What if I told you that for less than fifty bucks, you could start a wildflower garden covering 1,000 square feet of space? That’s a nice plot 25′ x 40′ or a strip 10′ wide and 100′ long along a driveway, field margin, roadside, property line, swale, or stream. All you need to do is cast seed evenly across bare soil in a sunny location and you’ll soon have a spectacular wildflower garden. Here at the susquehannawildllife.net headquarters we don’t have that much space, so we just cast the seed along the margins of the driveway and around established trees and shrubs. Look what we get for pennies a plant…
Here’s a closer look…
All this and best of all, we never need to mow.
Around the garden, we’ve used a northeast wildflower mix from American Meadows. It’s a blend of annuals and perennials that’s easy to grow. On their website, you’ll find seeds for individual species as well as mixes and instructions for planting and maintaining your wildflower garden. They even have a mix specifically formulated for hummingbirds and butterflies.
Nothing does more to promote the spread and abundance of non-native plants, including invasive species, than repetitive mowing. One of the big advantages of planting a wildflower garden or meadow is the opportunity to promote the growth of a community of diverse native plants on your property. A single mowing is done only during the dormant season to reseed annuals and to maintain the meadow in an early successional stage—preventing reversion to forest.
For wildflower mixes containing native species, including ecotypes from locations in and near the Lower Susquehanna River Watershed, nobody beats Ernst Conservation Seeds of Meadville, Pennsylvania. Their selection of grass and wildflower seed mixes could keep you planting new projects for a lifetime. They craft blends for specific regions, states, physiographic provinces, habitats, soils, and uses. Check out these examples of some of the scores of mixes offered at Ernst Conservation Seeds…

We’ve used their “Showy Northeast Native Wildflower and Grass Mix” on streambank renewal projects with great success. For Monarchs, we really recommend the “Butterfly and Hummingbird Garden Mix”. It includes many of the species pictured above plus “Fort Indiantown Gap” Little Bluestem, a warm-season grass native to Lebanon County, Pennsylvania, and milkweeds (Asclepias), which are not included in their northeast native wildflower blends. More than a dozen of the flowers and grasses currently included in this mix are derived from Pennsylvania ecotypes, so you can expect them to thrive in the Lower Susquehanna River Watershed.
In addition to the milkweeds, you’ll find these attractive plants included in Ernst Conservation Seed’s “Butterfly and Hummingbird Garden Mix”, as well as in some of their other blends.
Why not give the Monarchs and other wildlife living around you a little help? Plant a wildflower garden or meadow. It’s so easy, a child can do it.

The Mexican Cigar
You’ve heard and read it before—native plants do the best job of providing sustenance for our indigenous wildlife. Let’s say you have a desire to attract hummingbirds to your property and you want to do it without putting up feeders. Well, you’ll need native plants that provide tubular flowers from which these hovering little birds can extract nectar. Place enough of them in conspicuous locations and you’ll eventually see hummingbirds visiting during the summer months. If you have a large trellis, pole, or fence, you might plant a Trumpet Vine, also known as Trumpet Creeper. They become adorned with an abundance of big red-orange tubular flowers that our Ruby-throated Hummingbirds just can’t resist. For consistently bringing hummingbirds to the garden, Trumpet Vine may be the best of the various plants native to the Mid-Atlantic States.
There is a plant, not particularly native to our area but native to the continent, that even in the presence of Trumpet Vine, Pickerelweed, Partridge Pea, and other reliable hummingbird lures will outperform them all. It’s called Mexican Cigar (Cuphea ignea) or Firecracker Plant. Its red and yellow tubular flowers look like a little cigar, often with a whitish ash at the tip. Its native range includes some of the Ruby-throated Hummingbird’s migration routes and wintering grounds in Mexico and the Caribbean Islands, where they certainly are familiar with it.
This morning in the susquehannawildlife.net headquarters garden, the Ruby-throated Hummingbird seen in the following set of images extracted nectar from the Mexican Cigar blossoms exclusively. It ignored the masses of showy Trumpet Vine blooms and other flowers nearby—as the hummers that stop by usually do when Cuphea is offered.
Some garden centers still have Mexican Cigar plants available. You can grow them in pots or baskets, then bring them inside before frost to treat them as a house plant through the winter. Give the plants a good trim sometime before placing them outside when the weather warms in May. You’ll soon have Ruby-throated Hummingbirds visiting again for the summer.
