One of the colorful wood warblers that fascinate birders on their migration; this species was last seen in 1988 and is thus possibly extinct. Since the species is so rare, little has been described about its behavior.
The only parrot species native to continental North America. These gregarious birds showed close attachment to their own kind, when one of them died, a host of chattering birds promptly surrounded its body.
Once the most numerous species of bird on earth! They occurred in large flocks that appeared to blackout the sky for long periods of time. A flock of all Rock Pigeons, European Starlings and House Sparrows together would still not equal the number of Passenger Pigeons that once roamed the forests of eastern and central Canada and USA.
