A small plover with a very short bill. Its pale back matches the white sand beaches and alkali flats that it inhabits. While many shorebirds have wide distributions, this one is a North American specialty, barely extending into Mexico in winter. Many of its nesting areas are subject to human disturbance or other threats, and it is now considered an endangered or threatened species in all parts of its range.
Extensive freshwater marshes are the favored haunts of this large, stout, solitary heron. It is seldom seen as it slips through the reeds, but its odd pumping or booming song, often heard at dusk or at night, carries for long distances across the marsh.
Found in several scattered areas of North America, Sandhill Cranes reach their peak abundance at migratory stopover points on the Great Plains. The early spring gathering of Sandhills on the Platte River in Nebraska is among the greatest wildlife spectacles on the continent, with over a quarter of a million birds present at one time. Although they are currently very common, their dependence on key stopover sites makes them vulnerable to loss of habitat in the future.
One of our rarest songbirds, Kirtland's is a relatively large warbler that forages slowly, close to the ground, wagging its tail up and down. It nests only in stands of young jack pines in central Michigan, a habitat that grows up only briefly after fires, and its nests have been heavily parasitized in recent decades by Brown-headed Cowbirds. Controlled burning to create more habitat, and control of cowbird numbers, have helped the warbler somewhat, but it is not necessarily out of danger yet.
At one time, the eerie hollow moaning of male prairie-chickens displaying on their spring 'booming grounds' was a common sound across much of central and eastern North America. Today the prairie-chickens are quite uncommon and localized; the race on the Atlantic seaboard, called the Heath Hen, became extinct in 1932. Greater Prairie-Chickens still thrive on a few areas of native grassland in the midwest.
The Sora makes its presence known with plaintive whistles and whinnies rising from the marshes all across North America. Despite its abundance, it is not often seen: As with other rails, it spends most of its time hidden in dense marshy growth or wet meadows. Occasionally it will walk about in full view at the edge of a pond, delighting any birders who happen to be nearby. Although Soras might seem like weak fliers when seen fluttering over the marsh, they regularly migrate long distances, many going to South America for the winter.
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.
Fluttering over meadows and hayfields in summer, the male Bobolink delivers a bubbling, tinkling song which, loosely interpreted, gives the species its name. The male is unmistakable in spring finery, but before fall migration he molts into a striped brown appearance like that of the female. Bobolinks in this plumage were once known as 'ricebirds' in the South, where they occasionally used to cause serious damage in the ricefields.
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.
The most widespread grebe in the New World, and the most familiar in most temperate parts of North America. Far less sociable than most grebes, almost never in flocks, sometimes found singly on small marshy ponds. When disturbed or suspicious, it may sink slowly until only head is above water. Rarely seen in flight. Often secretive in the breeding season, hiding in marsh, making bizarre whinnying, gobbling, cooing noises by day or night.
One of the smallest herons in the world, the Least Bittern is adapted for life in dense marshes. Rather than wading in the shallows like most herons, the Least Bittern climbs about in cattails and reeds, clinging to the stems with its long toes. Its narrow body allows it to slip through dense, tangled vegetation with ease. Because of its habitat choice, it often goes unseen except when it flies, but its cooing and clucking calls are heard frequently at dawn and dusk, and sometimes at night.
