Going Cuckoo!

Black-billed Cuckoo

Black-billed Cuckoo

Here's a Yellow-billed Cuckoo

Black-billed Cuckoos are being seen now, they eat lots of caterpillars, are secretive and breed in forest habitats across much of the upper two-third of the U.S. from MT east and into southern Canada. Listen for their low pitched cu cu cu cu call. We saw one yesterday gleaning caterpillars at a forest edge. Tell them from the similar Yellow-billed Cuckoo by their black bill and red-eye ring. Yellow-billed Cuckoo has a yellow lower mandible and yellowish eye-ring and its breeding range extends across much of the eastern two-thirds of the U.S. Look for them now!
