Note: -Binomial name (Vanellus indicus) was given by Pieter Boddaert in 1783. The Red-wattled lapwing (Vanellus indicus) is an Asian Lapwing or large plover, a wader in the family charadriidae. Like other birds (Lapwing’s) they are ground birds that are incapable of perching. Their characteristic loud alarm calls are indicators of human or animal movements and the sounds have been variously Rendered as did he do it or pity to do it leading the the colloquial name of did he do it bird. Usually seen in pairs or small groups not far from water. They nest in a ground scrape laying three to four camouflaged eggs. Adults near the nest fly around, diving at potential predatiors while calling noisily. The crptically patterned chicks hatch and immediately follow their parents to feed, hiding by lying low on the ground or in the grass when threatened.
