Black-Billed Cuckoo
coccyzus erythropthalmus
The Black-Billed Cuckoo is a slender, stealthy bird of eastern North American woodlands, famous for its secretive habits and distinctive, rhythmic 'cu-cu-cu' calls. Often heard but rarely seen, this elusive insectivore spends its time deep within dense thickets and deciduous canopies, where it plays a crucial role in regulating pest populations. Unlike its European relatives, the Black-Billed Cuckoo typically builds its own nest and rears its own young, though it occasionally engages in opportunistic brood parasitism. Underneath its quiet demeanor lies an incredibly efficient hunter, highly adapted to preying on spiny caterpillars that most other birds avoid. Its arrival in late spring is a welcome sign for gardeners and foresters alike, signaling the natural control of seasonal caterpillar outbreaks.
生息地: Found in dense deciduous forests, thickets, and riparian woodlands, often near lakes or marshes where caterpillar populations are abundant.
外見
This medium-sized, slender bird is characterized by its olive-brown upperparts and clean, white underparts. It features a long tail with subtle white tips on the undersides of the feathers, a slim black bill, and a striking, bright red ring of bare skin around its dark eyes, which is a key identifier for adults. Its wingspan reaches up to 40 centimeters, allowing it to glide silently through dense foliage.

おもしろい事実
Their nesting cycle is incredibly rapid; chicks can leave the nest just six to seven days after hatching, climbing through branches before they can even fly.
They are famous for eating thousands of spiny caterpillars; to deal with the sharp, toxic hairs, they periodically shed and regrow their entire stomach lining.
While they usually build their own nests, they will occasionally lay eggs in the nests of other birds, especially when there is a massive outbreak of caterpillars.
