About These Birds
Blue Jay
The blue jay is a bold, intelligent member of the corvid family known for its striking plumage and loud calls. Blue jays are important dispersers of oak trees, as they cache thousands of acorns each autumn. Their complex social behavior includes mimicking the calls of hawks to scare other birds from feeders.
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.
