The yellow-billed cuckoo is a medium-sized bird known for its distinctive yellow bill and long tail. It has a brownish upper body and white underparts, often with faint streaks. This bird is primarily found in wooded areas, especially near rivers and wetlands, where it feeds on insects, particularly caterpillars. During the breeding season, the yellow-billed cuckoo builds its nest in trees and shrubs, laying 2 to 6 eggs. It is known for its unique call, which sounds like a series of "cow" notes. This species migrates to South America for the winter, returning to North America in spring.
