The animal on the cover of Learning from jQuery is an Asian green broadbill (Calyptomena viridis). It is distinct from the African green broadbill (Pseudocalyptomena graueri), also known as the Grauerâs broadbill. Despite Walter Rothschild christening the Grauerâs broadbill pseudocalyptomena, or âfalseâ Calyptomena, modern science has discovered that this bird is, in fact, related to the Asian green broadbill. Thus, both this bird and its cousin are true broadbill birds.
The Asian green broadbill is a small bird, averaging 15 cm in length. It has brilliant green and blue plumage, with black bars on its wings and a puff of feathers just above its beak. The broadbill is so named for its broad beak, although the beak itself is weak because this species primarily feeds on figs.
The broadbill inhabits evergreen trees in Malaysian and Indonesian forests, and is still fairly common, despite increasing habitat loss. This bird makes its nest out of lichen and spider webs, which camouflages the nests to look like arboreal litter.
