Black-billed Cuckoo

Black-billed Cuckoo

Coccyzus erythropthalmus

Introduction

An extremely rare autumn visitor, even rarer than Yellow-billed Cuckoo, this species has undergone a significant decline within its restricted North American breeding range.

Black-billed Cuckoos eat spiny caterpillars, the spines of which stick in the lining of the bird's stomach, so periodically the stomach lining is shed to remove the spines.
