Yellow-billed Cuckoo Identification

The Four Keys to ID

  • Size & Shape

    Yellow-billed Cuckoos are fairly large, long, and slim birds. The bill is almost as long as the head, thick and slightly downcurved. They have a flat head, thin body, and very long tail. Wings appear pointed and swept back in flight.

    Relative Size

    Longer, but slighter, than American Kestrel; about the size of a Blue Jay or Western Scrub-Jay.
