The Mangrove Cuckoo is a well-named species that occupies mangrove stands in Florida in the U.S., as well as mangroves and other forest types in the tropics of the Northern Hemisphere. They are a difficult bird for people to spot, as they are often found in very dense vegetation, and prefer tropical forested habitats that are sometimes difficult to investigate. They are typically heard much more often than they are seen.
Habitat
Found in in mangrove forests in the U.S. part of its range, as well as in some tropical hardwood species. In the rest of its tropical range, the Mangrove Cuckoo is found in mangroves, but also in other types of woodlands. Not necessarily always found near water in the tropics, with some birds nesting far from water sources.Diet
Feeds on insects and spiders, with a particular preference for caterpillars, like other cuckoo species. They will also sometimes feed on small vertebrates such as small frogs, and sometimes will feed on vegetative material such as fruits and berries.Behavior
Moves slowly through the branches and foliage of trees and shrubs, searching for insects.Nesting
The nest of a Mangrove Cuckoo is in a mangrove tree or other small tree, typically relatively close to the ground or water. The nest is a simple stick platform, upon which the female lays 2 or 3 eggs. Both parents help to incubate the eggs, and both parents help to feed the young after they hatch.Song
The song of a Mangrove Cuckoo is a nasal repeating series of notes that slowly speeds up, and end with a pair of lower, longer tones.Migration
Considered a permanent resident throughout its tropical range. They were once considered only a summer visitor in Florida. However, they have increasingly been identified during the winter months, and it may just be that overwintering birds are rarely seen due to the birds' habits and the dense habitat they typically occupy. There's little doubt that some birds are migratory, given that stray birds are sometimes seen in Texas and along the Gulf Coast.Interactive eBird Map

The Mangrove Cuckoo is a chunky, warm brown-and-buff tropical cuckoo of mangroves and dense coastal thickets in southern Florida, the Caribbean, and parts of Central America, with a heavy slightly downcurved bill and bold black mask through the eye. Both Yellow-billed Cuckoo and Black-billed Cuckoo are slimmer, longer-tailed migratory cuckoos widespread across much of eastern and central North America in summer, lacking the strong facial mask and looking grayer above with cleaner pale underparts. Yellow-billed shows warm cinnamon in the wings and large white spots in the tail, while Black-billed is plainer, grayer, and has a darker bill with less bold tail pattern.
