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.
Andaman Treepie
The Andaman Treepie is a vulnerable corvid with a 23.3 cm wingspan, weighing 102.5 grams, endemic to the Andaman Islands. It inhabits forest and woodland, foraging omnivourously for insects, fruit, and small animals. Its restricted range on the islands makes it conservation-dependent.
