The Baltimore Oriole breeds in eastern North America and winters in Central America. The female weaves a pouch-like nest that hangs from a branch.
Adult males have black heads and backs with orange breasts and tail feathers. Females vary more, with grey, brown or yellowish plumage.
From 1973 to 1975, researchers banded migrating birds at Welder Wildlife Refuge on the Texas coast. Their seasonal surveys recorded 8,504 birds from 98 species, preserving a detailed snapshot of migration through the region.
Baltimore Orioles were recorded only as passing migrants, not as birds staying to breed or winter at the refuge. Researchers banded 47 in autumn and 17 in spring, giving a seasonal comparison from one Gulf Coast site.
An extinction-risk assessment has not been added yet.
