This bird feeds primarily on insects, in particular beetles, crickets, and grasshoppers. It also regularly consumes flying insects such as wasps, flies, moths and butterflies (6). Where available, amphibians also form a large part of its diet, although in drier areas this food source is often not available (5). When hunting, the Indian roller typically sits motionless at a high vantage point, from which it can scan the ground for potential prey items. When prey is spotted, it will drop down to snatch it and then return immediately to its perch to consume it. On other occasions the Indian roller feeds directly from the ground, and moves around an area foraging for potential insect prey (6).
Breeding generally occurs in spring and early summer, and males begin to display as early as February. Courtship displays are highly elaborate, with males flying to great heights and tumbling back down whilst performing a range of aerobatics, calling harshly and beating their wings rapidly to flash their brilliantly coloured wings and tail (5). Eggs are usually laid in April in a hole in a tree or other structure, and are incubated for a period of up to 20 days, with young generally fledging after a period of 35 days. Although groups of Indian rollers are rarely seen, family groups may form, and communicate with a series of loud ‘chack’ calls, which become harsher and more regular during times of threat. When bathing, this species is often seen diving in to water from a great height, a behaviour which was once interpreted as fishing (5).
