They Go Together Like Corned Beef and Cabbage

Red-winged Blackbird
Find a stand of Common Cattails in a marsh, a stormwater basin, or along a pond edge right now and you’re almost certain to find a male Red-winged Blackbird …

…singing and displaying to defend a territory and attract a partner.  Upon their arrival and selection of a mate, the brown-streaked females will weave well-hidden nests among the stems and leaves of these essential water-purifying wetland plants.

A Visit to a Beaver Pond

To pass the afternoon, we sat quietly along the edge of a pond created recently by North American Beavers (Castor canadensis).  They first constructed their dam on this small stream about five years ago.  Since then, a flourishing wetland has become established.  Have a look.

The Sora (Porzana carolina) is a seldom seen rail of marshlands including those created by North American Beavers.  Common Cattails, sedges, and rushes provide these chicken-shaped wetland birds with nesting and loafing cover.

Isn’t that amazing?  North American Beavers build and maintain what human engineers struggle to master—dams and ponds that reduce pollution, allow fish passage, and support self-sustaining ecosystems.  Want to clean up the streams and floodplains of your local watershed?  Let the beavers do the job!

Female Red-winged Blackbirds in a cattail wetland.
This year’s unseasonably mild weather has hastened the northward migration of many birds.  Neotropical species including warblers and Broad-winged Hawks are already pushing through the lower Susquehanna region in numbers.  But it seems the spring movement may be a little bit protracted for female Red-winged Blackbirds, which are still rolling through by the hundreds despite the males being here, some of them defending nesting territories, since late February.  No sense of urgency?

Off To The Races

Trying to get a favorable place to nest before others arrive, the “early birds” are presently racing north through the lower Susquehanna valley.  Check out these sightings from earlier today…

Time to get outside and have a look.  The spectacle of spring migration passes quickly.  You don’t want to miss it!

Birds of Conewago Falls in the Lower Susquehanna River Watershed: American Bittern
The American Bittern (Botaurus lentiginosus) is a member of the Ardeidae, the heron and egret family.  It is a stealthy migrant, making its flights under cover of darkness, then resting and feeding in dense stands of Common Cattails and other marsh plants during the day.  It avoids detection by raising its bill skyward to create a profile and color scheme that blends well with the contours of the vegetation.  In Pennsylvania, loss of wetland habitat used for nesting has led to the American Bittern being listed as an endangered species.

Swamp Sparrows can be found year-round in the Lower Susquehanna River Watershed. They seldom occur far from water, this one spending its time in a dense stand of Common Cattails (Typha latifolia).
