Eastern Meadowlark – LIFE IN THE LOWER SUSQUEHANNA RIVER WATERSHED

Scenes from a Managed Grassland Ecosystem

Pretty pictures…

Veery — Photographing Neotropical migrants as they arrive to nest in our local forests can be frustrating under closed canopies and diffused light conditions. We instead decided to focus our efforts and lenses on the grassland species at Middle Creek Wildlife Management Area where, earlier this week, several prescribed fire burns were wrapping up the spring treatments for 2026.

Warm-season grassland — Managed warm-season grassland habitat at Middle Creek Wildlife Management Area.

Already tending nests containing eggs and young, Tree Swallows are scattered around the refuge’s grasslands to welcome newly arriving migrants, and human visitors!

Middle Creek is probably the best place in the lower Susquehanna valley to see ground-nesting Grasshopper Sparrows.

Grasshopper Sparrow and Tree Swallow — It’s a behavior that occasionally puts the newcomer Grasshopper Sparrow in conflict with a well-ensconced Tree Swallow guarding its nest box.

Eastern Bluebirds squeeze in among the Tree Swallows to find a vacant nest box within which they can raise their young.

Song Sparrows may be present year-round in grasslands with interspersed growth of early successional shrubs and briars, however the populations at a given location changes as birds migrate in and out of the area seasonally. Those individuals observed nesting here in the spring and summer are not usually the same birds seen during the late fall and winter.

As a species, the Savannah Sparrow, like the Song Sparrow, may be represented in the grasslands throughout the year, though the individuals vary with the changing seasons. Unlike the Song Sparrow which nests in shrubs, the Savannah Sparrow nests on the ground among thick grasses.

Still munching on the seeds of last year’s wildflowers, American Goldfinches are pairing up around the grasslands waiting for thistle down and other fibers to be available for nest construction. They will then build a small cup within the upper limbs of a small to medium-sized tree to shelter their eggs and nestlings.

The Common Yellowthroat, one of our Neotropical warblers, will reproduce in grasslands with scattered early successional thorny shrubs to afford a safe place to construct a nest. The males sing almost incessantly from the time they arrive in late April and early May until sometime in July, or even later.

Eastern Kingbirds are arriving from tropical wintering grounds to nest in grasslands and pastures throughout the lower Susquehanna region. They are a tyrant flycatcher that will ambush insects from a perch atop a tree, shrub, or tuft of tall grass.

Northern Mockingbirds are considered a resident species, though there may be some southward movement during severe winters when foods such as berries become scarce. At Middle Creek, some of these evacuees have returned to nest along the interface zone between the grassland and early successional shrub habitats.

Nesting Horned Larks apparently take advantage of the interface between the managed grasslands and nearly bare soils in spring-planted croplands at Middle Creek. They may be one of the few, possibly the only, species of bird life to take advantage of no-till farming for nesting on the ground.

Red-winged Blackbirds not only construct nests in cattails and other marsh growth, but in dense grasses and shrubs in and near grasslands and pastures. The males are easily seen displaying their plumage as they sing from a small tree, shrub, or a cattail seed spike.

Female Red-winged Blackbird — Less frequently seen is the female Red-winged Blackbird. She spends the majority of her time in the nest, but will periodically come out to join the ruckus when an intruder is being scolded into leaving the premises.

Another member of the blackbird family is the Eastern Meadowlark. It too is an energetic singer during the breeding season. Meadowlarks build their nests on the ground, often in pastures of cool-season grasses where harvests prior to August are fatal to eggs and young. Middle Creek’s managers delay harvests to allow the birds enough time to complete their reproduction cycle.

Another blackbird is the Bobolink, an obligate grassland specialist and a Neotropical migrant. One of its few uses for trees and shrubs is as a place to burst into display and song, though it will also perform these rituals on the wing and among the grass.

Bobolinks — As the males arrive, competition for suitable nesting sites among the grasses becomes intense, even before a female is anywhere in sight.

Did you know the Baltimore Oriole is a blackbird? Well, it is.

Baltimore Orioles — Competition for these ideal sites can get quite animated.

Western Cattle Egrets and Geese — It’s an unusual experience, watching Western Cattle Egrets feeding in a field of cultivated cool-season grasses alongside Snow Geese, though they certainly aren’t looking for the same thing.

We’ll have more on the Western Cattle Egrets and other interesting migrants at Middle Creek in an upcoming post. Check back soon!

Managing a Grassland Ecosystem

If you’ve visited Middle Creek Wildlife Management Area anytime during the past month, you may have noticed quite a bit of activity around the large pole-mounted nest boxes placed out in the open fields.

American Kestrels at nest box — American Kestrels, a male and female, at a nest box at Middle Creek Wildlife Management Area.

Kestrels competing for nesting sites and territory. — Within the past week, we noticed that kestrels are still competing for nesting sites and territory, driving away unwanted trespassers. A pair of kestrels seemed to be occupying each of the four box sites we observed. That’s good news, but the presence of these man-made nest cavities is in no way wholly responsible for this positive response from these declining birds. It’s a matter of habitat, much needed grassland habitat.

Cool Season Grasses — Cool-season grasses including fescue (Lolium species) and non-native Orchard Grass (Dactylis glomerata) mature by late spring. If left standing, they continue to provide indispensable habitat for grassland wildlife through the summer. Mowing early and often for hay harvest has rendered most cool-season meadows death traps for nesting birds. By delaying cuttings until at least early August, ground-nesting birds are given adequate time to fledge their young and get the juvenile birds strong enough to fly away from a set of spinning blades.

Grasshopper Sparrow in Timothy — A male Grasshopper Sparrow sings to demarcate its nesting territory in a stand of Timothy, an introduced species cultivated for harvest as hay. An insectivore during the breeding season, he and his mate will attempt to raise their brood exclusively within the cover of these cool-season grasses.

Orchard Grass with Black-eyed Susans — Prior to being mowed, Orchard Grass provides the short, dense cover meadowlarks and other ground-nesting grassland birds need to successfully reproduce. Growing a cool season grassland can be as easy as delaying the mowing of a pasture, field, or oversize lawn until August, then have a farmer friend come and take off a cutting or two of hay or straw to prevent woody plants from becoming established.

Warm-season Grasses — More durable stands of native warm-season grasses including Big Bluestem, Indiangrass, Switchgrass, and Little Bluestem thrive in the summer heat and provide wildlife habitat throughout the year. These perennial “prairie grasses”, fed by root systems five to eight feet deep, are especially drought tolerant . From these entrenched anchors, the plants would quickly bounce back after the once great herds of hungry bison had grazed the landscape bare of surface vegetation before moving on. This adaptation also assured “prairie grass” regeneration following naturally occurring seasonal fires, events mimicked in eastern North America by its pre-Columbian human residents. They used recurrent fire to perpetuate early successional habitat for wildlife propagation, foraging, and agriculture. Today in the lower Susquehanna watershed, establishing warm-season grassland meadows requires soil prep and seeding to get things going again.

Precribed Burn — To prevent succession, warm-season grassland parcels are most commonly maintained using applications of prescribed fire every 3 to 5 years. Among their benefits, these burns invigorate native vegetation while inhibiting the invasive tendencies of many non-native plants. Well-planned periodic fire can significantly reduce fuel accumulations, particularly in tinderbox woodland tracts managed as fire-free zones for the past century or more. Many forest trees including oaks rely on sporadic fire events for regeneration.

LEARN HOW LAND MANAGERS UTILIZE PRESCRIBED FIRE

This coming Saturday, April 18, 2026, beginning at 10 A.M. (rain date April 25), the Pennsylvania Game Commission is hosting a “Prescribed Fire Festival” at Middle Creek Wildlife Management Area. Be certain to come out to the visitor’s center at 100 Museum Road, Stevens, PA, for this event. Land managers will be there to answer questions and to explain the planning and preparations involved in overseeing a prescribed burn. There will be guided walks of habitats preserved using fire of varying intensities. You’ll see the equipment and protective clothing used by certified personnel to administer a live prescribed fire burn right before your eyes. Then you can have lunch—food trucks will be available on site.

After the burn demonstration, why not go for a walk or drive around the refuge. You can take note of how grassland and early successional plant communities are responding to previous doses of prescribed fire…

Greening up a week or two after the burn, Wingstem is blooming by June in areas treated using prescribed fire earlier in the spring.

Another scene from June: Four-foot-tall Joe-Pye-Weed amidst lush growth of goldenrod in early successional habitat where a prescribed burn eliminated accumulating wildfire fuel and turned back the growth of invasive plant species in March.

And how the grassland animals respond as well…

Ring-necked Pheasants in early successional habitat maintained by the periodic application of prescribed fire.

Eastern Cottontails prosper in the mosaic of warm-season grasses and early successional thickets on lands sustained using prescribed fire. Rabbits are herbivores, primary consumers eating mostly legumes and other plants, the producers that through the process of photosynthesis convert the energy of the the sun into food energy.

Other small vegetation-eating rodents including mice and voles thrive in managed grasslands. Similar in appearance are the shrews. Though seldom noticed, Northern Short-tailed Shrews spend day and night foraging for food, even in the shallow waters of wet meadows and thickets. Unlike the aforementioned herbivorous rodents, shrews are insectivores, secondary consumers feeding mostly on primary consumers including a variety of insects and other arthropods.

Some years ago, we found this tiny Masked Shrew (Sorex cinereus) in a grassland area being preserved using prescribed fire. Like other shrews, Masked Shrews are secretive, but always on the go. They feed constantly to fuel their vast energy requirements, sometimes consuming three times their body weight in a single day. But their voracious appetite can get them into trouble, causing these incessant eaters to encounter numerous potentially infective parasites during their non-stop foraging missions.

Female American Kestrel — Patrolling the grasslands is the female American Kestrel, a secondary consumer. She’s on the lookout for primary consumers including large insects like grasshoppers or crickets. But perhaps more likely is a small rodent whose less-than-ideal vigor may cause it to slip up, creating an easy target. If she selects a careless shrew as her prey, she may be assuming the role of a tertiary consumer, eating a secondary consumer (the shrew) that fed on insects (the primary consumers) that derived their energy from photosynthesized plant matter.

The strictly nocturnal American Barn Owl (Tyto furcata), another secondary and sometimes tertiary consumer, takes the night shift, hunting unwary voles, mice, and shrews, often by sensing the sounds they make among runways in the grass. As a native predator in its favored habitat, the owl’s selection of each victim actually helps to keep the prey species’ population healthy, eliminating the weak and vulnerable to provide a qualitative service to the surviving wildlife of the grasslands. While we may not think of the barn owl as a direct consumer of insects, its positive influence on insectivorous shrew populations makes it an important functionary in maintaining balance in the ecosystems it calls home.

Male American Kestrel — As food becomes increasing plentiful in the grasslands, a female kestrel will remain mostly out of sight, performing the majority of the egg incubation duties while her colorful mate stands guard nearby.

The fate of an avian predator such as a kestrel lies at the mercy of the fate of its quarry. Because, you see, the sun’s energy, after being converted to chemical energy by photosynthesizing plants, flows upward through the trophic levels of the food chain—herbivores (primary consumers) such as rodents and insects to carnivores (secondary and tertiary consumers) including kestrels. Grasslands, when abundant and diverse, are correspondingly abundant and diverse with small mammals and insects and will therefore support thriving populations of American Kestrels and other predators. These secondary and sometimes tertiary consumers fulfill a role in cultivating healthier populations of their prey—the primary and secondary consumers in the food web—as a balanced component of a flourishing grassland ecosystem. Sparse and fragmented grasslands, on the other hand, beget negligible small mammal and insect populations, are stricken with broken food webs, and champion few if any American Kestrels or other predators. If the land it occupies is neat, tidy, manicured, exploited, or sprayed sterile and dead, the energy flow cycle of the ecosystem is dead as well. There’s nothing animal introductions, reintroductions, rescues, culling, stocking, or harvesting can do about it, because in the end, it’s all about the habitat.

Back in the Day: Down on the Farm

Let us travel through time for just a little while to recall those sunny, late-spring days down on the farm—back when the rural landscape was a quiet, semi-secluded realm with little in the way of traffic, housing projects, or industrialized agriculture. Those among us who grew up on one of these family homesteads, or had friends who did, remember the joy of exploring the meadows, thickets, soggy springs, and woodlots they protected.

Low-intensity Farming — During much of the twentieth century, low-intensity agriculture provided a haven for wildlife. Periodic disturbances helped maintain cool-season grassland and early successional habitat for a number of species we currently find in decline.

For many of us, farmland was the first place we encountered and began to understand wildlife. Vast acreage provided an abundance of space to explore. And the discovery of each new creature provided an exciting experience.

Ned Smith's Birds of Field and Garden — Distributed by the Pennsylvania Game Commission, artist Ned Smith’s wildlife posters introduced many residents of the lower Susquehanna region to its birds and mammals. This poster of “Birds of Field and Garden” helped us learn what to expect and search for during our forays to the farm.

Today, high-intensity agriculture, relentless mowing, urban sprawl, and the increasing costs and demand for land have all conspired to seriously deplete habitat quality and quantity for many of the species we used to see on the local farm. Unfortunately for them, farm wildlife has largely been the victim of modern economics.

For old time’s sake, we recently passed a nostalgic afternoon at Middle Creek Wildlife Management Area examining what maintenance of traditional farm habitat has done and can do for breeding birds. Join us for a quick tour to remember how it used to be at the farm next door…

Always found nesting under the forebay of the barn, the Barn Swallow relentlessly pursued flying insects over the pond and meadow.

In the cherry grove down by the creek, the Orchard Oriole would be singing incessantly to defend its territory.

Normally seed eaters through the colder months, American Goldfinches would regularly find a source of protein in the occupants of Eastern Tent Caterpillar nests.

Along the wet margins of the creek, Yellow Warblers would nest in the shrubs and small trees.

The “Traill’s Flycatcher” was a familiar find in low-lying areas of successional shrubs and small trees. Today, “Traill’s Flycatcher” is recognized as two distinct species, the Alder Flycatcher (Empidonax alnorum) and the Willow Flycatcher. In the lower Susquehanna valley, the latter (seen here) is by far the most common of the two.

During the nineteenth century, Eastern Bluebirds became a rarity on lower Susquehanna farms due to a combination of factors: pesticide (DDT) use, habitat loss, and competition with other birds for nest sites. The species saw a resurgence beginning in the 1970s with discontinuation of DDT applications and widespread provision of nesting boxes. Around human habitations, competition with invasive House Sparrows continues to be detrimental to their success.

Purple Martins and Tree Swallows — Purple Martins suffered a similar fate to the bluebirds. The potential for their recovery remains dubious and they continue to be very local breeders, fussy about selection of suitable man-made provisions for nesting. After considerable effort, Purple Martins have at last been attracted to nest in the condos placed for their use at Middle Creek Wildlife Management Area. In the artificial gourds, there are nesting Tree Swallows, a species which also benefits from the placement of boxes intended for bluebirds.

Abandoned fields and other successional habitats were and continue to be favored homes for Field Sparrows.

At almost any time of year, roving bands of Cedar Waxwings would suddenly visit old field habitat looking for berries among the shrubs and other pioneering woody growth. In early summer, after most species have already hatched their young, nesting would commence and these fruit eaters would transform into accomplished fly catchers.

During the twentieth century prior to the 1980s, Ring-necked Pheasant populations in the Lower Susquehanna River Watershed were composed of breeding descendants of introduced birds supplemented by additional releases to maintain numbers sufficient for hunting. Year-round populations did and can reside in mosaic landscapes of early successional and grassland habitats, the latter including hay fields left unmowed through the nesting season.

Wildlife in the Burn Zone

During Saturday’s Prescribed Fire Demonstration at the Pennsylvania Game Commission’s Middle Creek Wildlife Management Area, we noticed just how fast some species of wildlife return to areas subjected to burns administered to maintain grassland habitat and reduce the risk of high-intensity blazes.

Back Fire Ignition during prescribed burn demonstration. — Pennsylvania Game Commission crews ignite a back fire to contain a prescribed burn along its downwind/upslope perimeter during a demonstration at Middle Creek Wildlife Management Area on Saturday.

Red-tailed Hawks and other raptors, including nocturnal owls, are frequently the first visitors attracted to the scene of a prescribed burn or wildfire. In grassland and successional habitats, they come looking for any vulnerable voles or mice that may be moving about looking for cover.

These three Eastern Meadowlarks spent the morning in the grassland areas adjacent to the prescribed fire site, mostly where a burn had been conducted one week prior. During the demonstration, one even perched and sang from the oak trees in the museum/visitor’s center parking lot.

Following the Prescribed Fire Demonstration, we decided to pay a visit to some of the parcels where burns had been administered one week earlier on the north side of Middle Creek’s main impoundment. We found a surprising amount of activity.

White-crowned and White-throated Sparrows — Apparently feeding upon slightly heat-treated seeds, sparrows were found by the dozens. White-crowned (left), White-throated (right), Song, and Savannah Sparrows were identified.

This Downy Woodpecker was finding something to its liking among the scorched leaves, stems, and twigs.

American Robins seem to find areas with lightly burnt vegetation and ash-dusted soil advantageous for finding invertebrates following a fire.

Mixed Flock of Blackbirds — We found this flock of Red-winged Blackbirds, Browned-headed Cowbirds, and a few European Starlings feeding throughout a grassland field cleared of early-successional growth by a prescribed fire administered one week ago.

Birds of Snow-covered Farmland

When the ground becomes snow covered, it’s hard to imagine anything lives in the vast wide-open expanses of cropland found in the Lower Susquehanna River Watershed’s fertile valleys.

Snow-covered Farm Field — A snow-covered field with no standing vegetation. For nearly all wild birds, mammals, and other animals, modern agricultural practices offer no means of sustenance, particularly during the winter months.

Yet, there is one group of birds that can be found scrounging a living from what little exists after a season of high-intensity farming. Meet the Horned Lark.

Horned Larks occur year-round in the lower Susquehanna region. Birds found wintering here are hardy individuals that breed in the arctic tundra, terrain reminiscent of our treeless farmlands. Another population of larks seems to have adapted to no-till farming, nesting with some success in unplowed fields during the early part of the growing season. The impact of herbicide application on survival of these broods could be a topic of research for an energetic student out there…hint, hint.

A Flock of Horned Larks — Nearly invisible on bare ground, Horned Larks are much more conspicuous after a fresh snowfall. For protection from predators, they gather in flocks. During the days of raw manure application, 300 to 500 larks could be found attracted to a freshly spread strip in a snow-covered field. Modern liquid manure, which contains fewer undigested seeds and grains for larks, is not as attractive to these and other birds.

Horned Larks in Snow — During severe storms, we’ve seen Horned Larks remain active throughout the night. We’ve even witnessed them taking shelter by burying themselves in the snow.

Horned Lark in Flight — To find food, Horned Larks are constantly on the move…

Horned Larks Feeding at Roadside — Following storms, Horned Larks often gather along roadsides where snow removal has revealed “weed” seeds and other tiny morsels that, though they are almost imperceptible to us, are a meal for a Horned Lark.

Horned Larks and Lapland Longsrurs — Flocks of wintering Horned Larks will sometimes contain one or more of the several much less numerous species with a similar proclivity for tundra-like environs during the colder months. We examined this gathering a little bit more closely…

Lapland Longspurs and Horned Larks — …and found these Lapland Longspurs (Calcarius lapponicus). In winter, Lapland Longspurs (the two streaked birds: one to the far left and the other high-stepping the white line) can be hard to discern from the earth tones of farmland habitat. Breeding males, however, are a brilliant white with a chestnut-colored nape and a black bib, mask, and cap. On rare occasions, these males in spectacular alternate plumage can be found in the lower Susquehanna valley prior to their departure to nesting areas near the treeline in northern Canada and Alaska.

A close-up image (through the windshield) of a roadside flock of Horned larks and three Lapland Longspurs (top, far right, and third from bottom).

If you decide to take a little post-storm trip to look for Horned Larks and Lapland Longspurs, be sure to drive carefully. Do your searching on quiet rural roads with minimal traffic. Stop and park only where line-of-sight and other conditions allow it to be done safely. Use your flashers and check your mirrors often. Think before you stop and park—don’t get stuck or make a muddy mess. And most important of all, be aware that you’re on a roadway—get out of the way of traffic.

If you’re not going out to look for larks and longspurs, we do have a favor to ask of you. Please remember to slow down while you’re driving. Not only is this an accident-prone time of year for people in cars and trucks, it’s a dangerous time for birds and other wildlife too. They’re at greatest peril of getting run over while concentrated along roadsides looking for food following snow storms.

The American Pipit is another barren-field specialist that can be found feeding at roadside following snowstorms, particularly when they coincide with the bird’s migration in late fall or early spring. (Vintage 35 mm image)

The Snow Bunting (Plectrophenax nivalis), like the Lapland Longspur, occurs among flocks of Horned Larks in winter. Other barren-ground birds you’ll see feeding along country roads following significant snowfalls include Savannah and Vesper Sparrows.

During mild winters, Killdeer may linger in farmlands where they are more easily heard than seen…until it snows.

This Week at Regional Hawk Watches

With nearly all of the Neotropical migrants including Broad-winged Hawks gone for the year, observers and counters at eastern hawk watches are busy tallying numbers of the more hardy species of diurnal raptors and other birds. The majority of species now coming through will spend the winter months in temperate and sub-tropical areas of the southern United States and Mexico.

Here is a quick look at the raptors seen this week at two regional counting stations: Kiptopeke Hawk Watch near Cape Charles, Virginia, and Second Mountain Hawk Watch at Fort Indiantown Gap, Pennsylvania.

Second Mounatin Hawk Watch — A Sharp-shinned Hawk is counted as it swoops by the owl decoy at Second Mountain Hawk Watch at Fort Indiantown Gap Military Reservation. Migrating raptors save energy by riding updrafts of air created by winds blowing against the slopes of the mountainsides in the Ridge and Valley Province.

A Sharp-shinned Hawk passes the lookout at Second Mountain Hawk Watch. “Sharp-shins” are currently the most numerous migrants both on the coast and at inland counting stations.

Sharp-shinned Hawk at owl decoy. — A Sharp-shinned Hawk eyes up an owl decoy. Under cover of darkness, nocturnal owls could rather easily prey upon young and small adult hawks and falcons, both on the nest or at roost. Accordingly, many diurnal raptors instinctively harass owls to drive them from their presence. An owl decoy at the lookout helps attract migrating birds for a closer look.

Cooper's Hawk — An adult Cooper’s Hawk flaps its way past a counting station. Like the similar Sharp-shinned Hawk, the larger Cooper’s Hawk is a member of the genus Accipiter. As a proportion of the annual fall Accipiter flight, the Cooper’s Hawk is more numerous at coastal hawk watches than at inland sites. (Editor’s Update: As of autumn, 2024, the Cooper’s Hawk and the American Goshawk have been placed in the genus Astur. The Sharp-shinned Hawk remains in the genus Accipiter. Though the Cooper’s Hawk and Sharp-shinned Hawk are oft times confused by observers due to their like appearance, it turns out that the two are not as closely related as originally believed. Neither is an offshoot of the other, nor do they descend from an immediate common ancestor. Their resemblance may instead be a case of convergent evolution, most readily characterized by acquisition of similar physical traits due to shared demands for survival within their environment.)

The majority of Osprey migrate along the coast, but a few are still being seen at inland hawk watches.

Bald Eagles are commonly seen at both coastal and inland lookouts. Their movements continue well into late fall.

The American Kestrel, like our other falcons, is seen in greatest concentrations at coastal counting stations. It is our most numerous falcon.

The Merlin provides only a brief observation opportunity as it passes the lookout. These falcons are dark, speedy, and easily missed as they fly by.

Merlin with Dragonfly — A Merlin consumes a dragonfly. Eating is no reason to stop moving.

Juvenile "Tundra Peregrine" — The “Tundra Peregrine” is an arctic-breeding Peregrine Falcon that travels a distance of over 6,000 miles to southern South America for winter. It is strictly a migratory species in our region with numbers peaking during the first two weeks of October each year. These strong fliers have little need for the updrafts from mountain ridges, inland birds often observed flying in a north to south direction. The majority of “Tundra Peregrines” are observed following coastlines, with some migrating offshore to make landfall at points as far south as Florida and the Caribbean islands before continuing across water again to reach the northern shores of Central and South America. This “Tundra Peregrine” is a juvenile bird on its first southbound trip.

During coming days, fewer and fewer of these birds will be counted at our local hawk watches. Soon, the larger raptors—Red-tailed Hawks, Red-shouldered Hawks, and Golden Eagles—will be thrilling observers. Cooler weather will bring several flights of these spectacular species. Why not plan a visit to a lookout near you? Click on the “Hawkwatcher’s Helper: Identifying Bald Eagles and other Diurnal Raptors” tab at the top of this page for site information and a photo guide to identification. See you at the hawk watch!

It’s not all hawks at the hawk watch. Even the coastal sites are now seeing fun birds like the playful Common Raven on a regular basis.

Some Good Reasons to Postpone Mowing Until Mid-August

Here in a series of photographs are just a handful of the reasons why the land stewards at Middle Creek Wildlife Management Area and other properties where conservation and propagation practices are employed delay the mowing of fields composed of cool-season grasses until after August 15 each year.

At places like Middle Creek Wildlife Management Area where a mix of grasslands, early successional growth, and even some cropland are maintained, the Blue Grosbeak has extended its range well north of the Mason-Dixon and has become a regular nesting species during recent decades. Good habitat management does pay dividends.

Right now is a good time to visit Middle Creek Wildlife Management Area to see the effectiveness a delayed mowing schedule can have when applied to fields of cool-season grasses. If you slowly drive, walk, or bicycle the auto tour route on the north side of the lake, you’ll pass through vast areas maintained as cool-season and warm-season grasses and early successional growth—and you’ll have a chance to see these and other grassland birds raising their young. It’s like a trip back in time to see farmlands they way they were during the middle years of the twentieth century.

The Colorful Birds Are Here

You need to get outside and go for a walk. You’ll be sorry if you don’t. It’s prime time to see wildlife in all its glory. The songs and colors of spring are upon us!

Flooding that resulted from mid-week rains is subsiding. The muddy torrents of Conewago Falls are seen here racing by the powerhouse at the York Haven Dam.

Receding waters will soon leave the parking area at Falmouth and other access points along the river high and dry.

Migrating Yellow-rumped Warblers are currently very common in the riparian woodlands near Conewago Falls. They and all the Neotropical warblers, thrushes, vireos, flycatchers are moving through the Susquehanna watershed right now.

A Baltimore Oriole feeds in a riverside maple tree.

Ruby-crowned Kinglets are migrating through the Susquehanna valley. These tiny birds may be encountered among the foliage of trees and shrubs as they feed upon insects .

Gray Catbirds are arriving. Many will stay to nest in shrubby thickets and in suburban gardens.

American Robins and other birds take advantage of rising flood waters to feed upon earthworms and other invertebrates that are forced to the soil’s surface along the inundated river shoreline.

Spotted Sandpipers are a familiar sight as they feed along water’s edge.

The Yellow Warbler (Setophaga petechia) is a Neotropical migrant that nests locally in wet shrubby thickets. Let your streamside vegetation grow and in a few years you just might have these “wild canaries” singing their chorus of “sweet-sweet-sweet-I’m-so-sweet” on your property.

If you’re not up to a walk and you just want to go for a slow drive, why not take a trip to Middle Creek Wildlife Management Area and visit the managed grasslands on the north side of the refuge. To those of us over fifty, it’s a reminder of how Susquehanna valley farmlands were before the advent of high-intensity agriculture. Take a look at the birds found there right now.

Red-winged Blackbirds commonly nest in cattail marshes, but are very fond of untreated hayfields, lightly-grazed pastures, and fallow ground too. These habitats are becoming increasingly rare in the lower Susquehanna region. Farmers have little choice, they either engage in intensive agriculture or go broke.

Nest boxes are provided for Tree Swallows at the refuge.

Numbers of American Kestrels have tumbled with the loss of grassy agricultural habitats that provide large insects and small rodents for them to feed upon.

White-crowned Sparrows (Zonotrichia leucophrys) are a migrant and winter resident species that favors small clumps of shrubby cover in pastures and fallow land.

When was the last time you saw an Eastern Meadowlark (Sturnella magna) singing “spring-of-the-year” in a pasture near your home?

And yes, the grasslands at Middle Creek do support nesting Ring-necked Pheasants (Phasianus colcichus). If you stop for a while and listen, you’ll hear the calls of “kowk-kuk” and a whir of wings. Go check it out.

And remember, if you happen to own land and aren’t growing crops on it, put it to good use. Mow less, live more. Mow less, more lives.
