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 black spots. This bird is primarily found in North America, especially in areas with dense vegetation near water sources, such as rivers and wetlands. Yellow-billed Cuckoos are known for their unique call, which sounds like a series of "cow" notes. They primarily feed on insects, particularly caterpillars, and are known to be migratory, traveling south to Central America during the winter months. Their population has been affected by habitat loss and changes in land use.
