Gull the exceptions being Sabine's gull and swallow-tailed gulls, which have forked tails, and Ross's gull, which has a wedge-shaped tail. Gulls have moderately long legs, especially when compared to the similar terns, with fully webbed feet. The bill is generally heavy and slightly hooked, with the larger species having stouter bills than the smaller species. The bill colour is often yellow with a red spot for the larger white-headed species and red, dark red or black in the smaller species. The gulls are generalist feeders. Indeed, they are the least specialised of all the seabirds, and their morphology allows for
Fork-tailed drongo-cuckoo known how or whether the drongo-like appearance benefits this species but it is suspected that it aids in brood-parasitism just as hawk-cuckoos appear like hawks. Some recent work suggested that the species was conspecific with the square-tailed drongo-cuckoo and together known as the Asian drongo-cuckoo, but should be split based on call and morphological differences. Fork-tailed drongo-cuckoo The fork-tailed drongo-cuckoo ("Surniculus dicruroides") is a species of cuckoo that resembles a black drongo. It is found resident mainly in peninsular India in hill forests although some specimens are known from the Himalayan foothills. It can be easily distinguished by its straight
