At a Glance
Birders who seek the Mangrove Cuckoo in Florida may have to contend with heat, humidity, mosquitoes, and long hours of searching. This bird is a shy denizen of dense mangrove swamps, living in impenetrable tangles, where its presence is often betrayed only by its throaty calls.

Behavior
Eggs
2, sometimes 3. Pale blue-green, fading to greenish yellow. Incubation is probably by both parents; incubation period not well known.
Young
Development of young and age at first flight not well known. Probably fed by both parents, as in other cuckoos.
Feeding Behavior
Forages rather slowly and deliberately among mangroves or other dense growth, peering about, sometimes making short leaps or flutters to take insects from the foliage.
Diet
Mostly insects. Diet not known in detail. As with other cuckoos, seems to eat many caterpillars. Also feeds on grasshoppers, praying mantises, moths, flies, and other insects; also some spiders and small frogs, and probably some berries and small fruits.
Nesting
Breeding behavior is not well known. Male gives low, throaty song in spring, presumably to defend territory and attract a mate. Nest: So far as known, site is in mangrove or other low tree, usually fairly low over the water or ground (probably lower than 10' in most cases), among dense foliage. Nest is a flimsy platform of sticks.
Climate Vulnerability
Conservation Status
Probably declining in Florida Keys as habitat is lost to development, but may be expanding north slightly along coast. Still widespread in Caribbean and elsewhere in tropics.
