About These Birds
American Crow
The American crow is one of North America's most familiar and intelligent birds. Research has shown they can recognize individual human faces and communicate perceived threats to other crows. They form large winter roosts of up to hundreds of thousands of individuals in some cities.
Budgerigar
The budgerigar is the third most popular pet in the world after dogs and cats, and by far the most common pet parrot. Wild budgies travel in enormous nomadic flocks that can darken the sky. Males can learn to mimic human speech, with one record-holding budgie having a vocabulary of 1,728 words.
