Dark-billed Cuckoo Coccyzus melacoryphus

  • Order: Cuculiformes
  • Family: Cuculidae
  • Monotypic
  • Authors: Adam Damon

Demography and Populations

Wikelski et al. (2004) suggested that Dark-billed Cuckoo population declines in the Galápagos might be due to parasites, such as a botfly species (Philornis downsi) that can significantly lower fledgling success in birds, and a parasitic nematode (Dispharynx spiralis) that may have been partially responsible for high cuckoo mortality observed in 1998 (Vargas and Bensted-Smith 2000). It is not known whether these parasites are endemic or were introduced.

There is no information related to topics such as age at first breeding, life span and survivorship, dispersal, or population regulation for Dark-billed Cuckoo.
