A paragraph on the mating system of the Yellow-billed Cuckoo in a
species account at the California Partners in Flight Riparian Bird
Conservation Plan web site
http://www.prbo.org/calpif/htmldocs/species/riparian/yellow- ;
billed_cuckoo.htm says:
In one case, post-hatching parasitism has been observed when a live
chick was dumped into another cuckoo pairs nest and was successfully
raised by the adoptive parents (Laymon et al. 1997).
