The white-rumped vulture was once India’s most common vulture — and perhaps the most numerous large bird of prey in the world. But between the mid-1990s and 2006, its population plummeted by 99.9%, and it’s now considered critically endangered.

The Asian koel is a brood parasite that lays its eggs in the nests of other birds. The species is also sexually dimorphic: males are dark-feathered goths, while females are boldly streaked in brown and white.

The Asian openbill uses its "open bill" to locate and grab its favourite prey — freshwater snails — using the sharp tip of its curved, lower mandible to extract them from their shells. It is a common species of stork throughout South and Southeast Asia.

The coppersmith barbet — a small bird about 16 cm (~6 in) long — often falls victim to bullying by other birds. Blue-throated barbets have been observed evicting coppersmiths from nesting holes, while red-vented bulbuls steal berries from male coppersmiths that are trying to feed their mates.

The black drongo keeps its neighbourhood clear of predators by fearlessly assailing them — as a result, other birds like orioles, doves, babblers, and bulbuls like to nest near the drongo. But the drongo is also a trickster, mimicking the calls of raptors to scare birds into abandoning their food.

While the spotted owlet is nocturnal, it can sometimes be seen during the day — it will bob its head and stare intensely at anyone who bothers it. This owlet can be located by watching for the small birds that often mob it or — during dusk and dawn — by the owlet's “chirurr-chirurr-chirurr” chuckle.
