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.
Asir Magpie
The Asir Magpie is an Endangered corvid restricted to the Asir Mountains of southwestern Saudi Arabia. Weighing about 200g with a wingspan of 38.9cm, it resembles other magpies with black-and-white plumage and a long tail. Its extremely limited range and habitat degradation make it one of Arabia's most threatened birds.
