Euphagus Carolinus - Rusty Blackbird found in the US

The rusty blackbird, Euphagus carolinus is a medium-sized blackbird with grackle-like plumage (“rusty grackle” is an older name for the species). It is a wet forested bird that breeds in boreal forest and muskeg in northern Canada and migrates southeast to the United States during the winter. Previously plentiful, the rusty blackbird has had one of the most precipitous losses of any abundant bird species in recent years, for unknown causes.

Size

These birds have a length of 8.25-9.75 in (21-25 cm) and a weight of 65 g (2.3 oz). Their wings could range from 13-15 in (33-38 cm).

Feeding

This species mostly forages on the ground, notably around the borders of ponds, streams, and other wetlands. During the winter, it will occasionally eat in trees on pine seeds, fruits, and berries.

Habitat

Throughout Canada and Alaska, they breed in moist temperate coniferous woods and muskeg, which provide a natural breeding ground. In most cases, birds nest around the edges of ponds and marshes, with the cup nest being built in a tree or thick bush, frequently above the water.

Behavior

They eat insects, small fish, and seeds, usually on damp ground or in shallow water. Their preferred way of foraging is to flip leaves and rip at submerged aquatic vegetation. The mast of small-acorn-producing oaks like the willow oak is also noteworthy. Plantation pecan nuts are frequently utilized in various areas. They seldom target small passerine birds but have been spotted killing huge birds like the common snipe. They browse in big groups during migration and wintering, occasionally joining other blackbirds, who also forage in large groups.
