Euphagus carolinus
| Conservation status | Although its remote breeding range and swampy winter habitat make it difficult to census, some scientists believe that the total population of this species may have declined by more than 80 percent in recent decades. |
|---|---|
| Family | Blackbirds and Orioles |
| Habitat | River groves, wooded swamps; muskeg in summer. Breeds in the muskeg region, in wet northern coniferous forest with many lakes and bogs. During migration and winter, favors areas with trees near water, as in wooded swamps and riverside forest; will also forage in open fields and cattle feedlots with other blackbirds. |
Forages mostly by walking on wet ground or wading in shallow water. May be solitary or in flocks. May join flocks of other blackbirds and feed with them in dry fields.
4-5, sometimes 3-6. Pale blue-green, spotted with brown and gray. Incubation is by female only, probably about 14 days. Young: Both parents feed nestlings. Young leave the nest about 11-14 days after hatching.
Both parents feed nestlings. Young leave the nest about 11-14 days after hatching.
Mostly insects and seeds. Majority of annual diet is insects, including many aquatic insects such as caddisflies, mayflies, dragonflies, and water beetles, plus land insects such as grasshoppers and others. Also eats snails, crustaceans, small fish, small salamanders. Eats many seeds and waste grain, especially in winter, also a few berries.
Sometimes nests in small, loose colonies, but more typically in isolated pairs. Male gives harsh, grating song in spring, to defend nesting territory or to attract a mate. Nest site is in dense cover, usually in conifer or in shrubs above the water; placed very low, typically only a few feet above water or ground, but can be up to 20' high in coniferous tree. Nest (built by female) is a bulky open cup of twigs and grass, often with foundation of Usnea lichens, the inner bowl shaped of mudlike decaying plant material from the forest floor; lined with fine grass.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.
As President Trump’s first term nears its end, major land-use decisions are coming due, with massive stakes for the environment.
Students at Brattleboro Union High School use art to channel both their climate grief and love for birds.
To justify its position, the agency is choosing to blatantly disregard the health impact to humans and wildlife, critics warn.
