a shrike or flycatcher, waiting on an open perch high in a tree to sally out and catch insects in flight or to pounce upon rodents and similar small vertebrates (such as other birds' chicks). It will also take prey (such as small lizards and frogs) and some fruit from vegetation by gleaning and jumping for it or ripping it off in mid-hover, and occasionally dives for fish or tadpoles in shallow water, making it one of the few fishing passerines. Kiskadees like to hunt on their own or in pairs, and though they might be expected to make good use of prey flushed by but too large for the smaller birds of the understory, they do not seem to join mixed-species feeding flocks very often. When they do, they hunt in the familiar manner. Such opportunistic feeding behavior makes it one of the commonest birds in urban areas around Latin America; its flashy belly and its shrill call make it one of the most conspicuous. Breeding Great kiskadees are monogamous and defend a territory. Both sexes build the large domed nest that has a side entrance. It is chiefly composed of grasses and small twigs but can also incorporate lichen, string and plastic. The birds will steal material from other nests. The nest is placed in a wide range of sites, often in an exposed position high up in a tree or on man-made structures. Occasionally the nest is placed in a cavity. The clutch is 3 to 4 eggs. These are moderately glossy, light yellowish cream in colour with purplish black and purplish brown spots. The average size is . Only the female incubates the eggs; the male guards the nest while she leaves the nest to feed. The eggs hatch after 16–17 days. The chicks are fed by both parents and fledge after 17–18 days. Food and feeding This alert and aggressive bird has a strong and maneuverable flight, which it uses to good effect when it feels annoyed by raptors. Even much larger birds are attacked by the great kiskadee, usually by diving down or zooming straight at them while they are in mid-air. Harsh calls are also often given during these attacks, alerting all potential prey in the area of the predator's presence. If not very hungry, any raptor subject to a great kiskadee's mobbing behavior is likely to leave, as it is well-nigh impossible
