Yellow-billed cuckoo (_Coccyzus americanus_) is a medium-sized migratory bird belonging to the cuckoo family, Cuculidae. It is characterized by a long, slender body, long tail, and a distinctive yellow bill. The yellow-billed cuckoo breeds in North America and winters in South America. It is an insectivore, feeding primarily on caterpillars, and is also known to eat fruits and berries. The yellow-billed cuckoo is a species of conservation concern due to habitat loss and fragmentation.
Yellow-billed cuckoos were once common throughout North America, but their populations have declined significantly in recent decades due to habitat loss and fragmentation. The birds rely on large tracts of forest for nesting and foraging, and as these forests have been cleared or fragmented, the cuckoos have lost their habitat. Climate change is also a threat to yellow-billed cuckoos, as it is causing their breeding grounds to shift northward.
