Slow Down When There’s Snow on the Ground

It’s just common sense to take it easy and drive carefully when snow covers streets and highways.  Everyone knows that.  But did you know that slowing down when the landscape is blanketed in white can save lives even after the roadways have been cleared?

Following significant snowfalls such as the one earlier this week, birds and other wildlife are attracted to bare ground along the edges of plowed pavement.  They are often so preoccupied with the search for food that they ignore approaching cars and trucks until it is too late.

Take a look at the species found today along a one mile stretch of plowed rural roadway in the lower Susquehanna valley.

Following snow storms, birds that normally feed among leaf litter on the forest floor or in thickets and fields are attracted to plowed roads.  During their urgent search for food, many are struck and killed by motor vehicles.
White-throated Sparrows commonly congregate along roads passing through woodlands and thickets.
A juvenile White-crowned Sparrow looks for food among leaves along the edge of snow-free pavement.
Adult White-crowned Sparrows take cover in roadside shrubs until traffic passes.  Within moments they’ll return to a patch of bare ground along the road’s narrow shoulder.
Dark-eyed Juncos are commonly encountered along roads through snow-covered weedy fields and suburbia.
Song Sparrows gather along roads traversing brushy areas.
Juvenile White-crowned Sparrows and, to the upper right, an American Tree Sparrow (Spizella arborea) take refuge in a small roadside sapling after fleeing a passing automobile.
This Yellow-rumped Warbler was attracted to berry-laden shrubs and vines in a road cut with a southern exposure and patches of bare ground.
Following a snowfall, Eastern Bluebirds are regularly seen feeding along the edges of rural roads.
Horned Larks gather along the snow-free margins of roads through tundra-like farmland.

For many species of wildlife in the Lower Susquehanna River Watershed, the fragmented and impaired state of habitat already challenges their chances of surviving the winter.  Snow cover can isolate them from their limited food supplies and force them to roadsides and other dangerous locations to forage.  Mauling them with motor vehicles just adds to the escalating tragedy, so do wildlife and yourself a favor—please slow down.

Even in areas with  ideal habitat, snow cover will cause birds and other wildlife to explore bare ground along highways while seeking food.
Ring-necked Pheasants frequently become traffic casualties.  These birds feeding at roadside due to the snow cover are in increased peril.

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.
