Birds of Constitution Marsh

One of our most popular birds, the Cardinal is the official state bird of no fewer than seven eastern states. Abundant in the Southeast, it has been extending its range northward for decades, and it now brightens winter days with its color and its whistled song as far north as southeastern Canada. Feeders stocked with sunflower seeds may have aided its northward spread. West of the Great Plains, the Cardinal is mostly absent, but it is locally common in the desert Southwest.

Among our most familiar birds, Red-wings seem to sing their nasal songs in every marsh and wet field from coast to coast. They are notably bold, and several will often attack a larger bird, such as a hawk or crow, that flies over their nesting area. The red shoulder patches of the male, hidden under body feathers much of the time, are brilliantly displayed when he is singing. Outside the nesting season, Red-wings sometimes roost in huge concentrations.

A sputtering, bubbling song among the cattails is a giveaway that the Marsh Wren is at home. A patient watcher eventually will see the bird as it slips furtively through the reeds or bounces to the top of a stem for a look around. Industrious male Marsh Wrens build 'dummy nests' in their nesting territories, occasionally up to twenty or more; most of these are never used for raising young, but the adults may sleep in them during other seasons.

Widespread and familiar (though often called 'crane'), the largest heron in North America. Often seen standing silently along inland rivers or lakeshores, or flying high overhead, with slow wingbeats, its head hunched back onto its shoulders. Highly adaptable, it thrives around all kinds of waters from subtropical mangrove swamps to desert rivers to the coastline of southern Alaska. With its variable diet it is able to spend the winter farther north than most herons, even in areas where most waters freeze. A form in southern Florida (called 'Great White Heron') is slightly larger and entirely white.

Abundant over most of the northern hemisphere, the Mallard is the most familiar wild duck to many people, and the ancestor of most strains of domesticated ducks. In many places this species has managed to domesticate itself, relying on handouts in city parks. Although barnyard and feral ducks may be dumpy and ungainly creatures, the ancestral wild Mallard is a trim, elegant, wary, fast-flying bird.

Our smallest dabbling duck. Very common and widespread, remaining through the winter farther north than other teal. Often rests out of the water, even standing on low snags or branches. Flocks in flight appear very fast because of small size, with rapid twisting and turning in unison. Typically travels in small flocks, but in winter or at migration stopovers, may gather in concentrations of thousands.

The emblem bird of the United States, majestic in its appearance. It is not always so majestic in habits: it often feeds on carrion, including dead fish washed up on shore, and it steals food from Ospreys and other smaller birds. At other times, however, it is a powerful predator. Seriously declining during much of the 20th century, the Bald Eagle has made a comeback in many areas since the 1970s. Big concentrations can be found wintering along rivers or reservoirs in some areas.

Beautiful and unique, this duck of woodland ponds and river swamps has no close relatives, except for the Mandarin Duck of eastern Asia. Abundant in eastern North America in Audubon's time, the Wood Duck population declined seriously during the late 19th century because of hunting and loss of nesting sites. Its recovery to healthy numbers was an early triumph of wildlife management.

The Belted Kingfisher is often first noticed by its wild rattling call as it flies over rivers or lakes. It may be seen perched on a high snag, or hovering on rapidly beating wings, then plunging headfirst into the water to grab a fish. Found almost throughout North America at one season or another, it is the only member of its family to be seen in most areas north of Mexico.

A big, dashing bird with a flaming crest, the largest woodpecker in North America (except the Ivory-bill, which is almost certainly extinct). Excavating deep into rotten wood to get at the nests of carpenter ants, the Pileated leaves characteristic rectangular holes in dead trees. This species became rare in eastern North America with clearing of forests in centuries past, but has gradually increased in numbers again since about the beginning of the 20th century. Where unmolested, it even lives in parks and woodlots around the edges of large cities.

This is the most widespread of the three bluebirds. Although it is mostly 'eastern' in our area, its total range extends south to Nicaragua. A high percentage of Eastern Bluebirds in North America today nest in birdhouses put up especially for them along 'bluebird trails.' When they are not nesting, these birds roam the countryside in small flocks.
