Sp. Charact. — Glossy black; head and neck blackish-brown. — - 
Female wholly sooty-brown, beneath pale. — Young similar to 
the female, with the breast spotted. 
The Cow-pen Bird, perpetually gregarious and flit- 
ting, is observed to enter the Middle and Northern States 
in the latter end of March or the beginning of April. 
They make their migration now chiefly under cover of the 
night, or early dawn ; and as the season becomes milder 
they pass on to Canada, and perhaps follow the Warbler^ 
and other small birds into the farthest regions of the 
north, for they are seen no more after the middle of June 3
