Available in PDF, EPUB and Kindle. Book excerpt: Cowbirds are an ideal group in which to study the biology of brood parasitism; within the six included species there are displayed all stages of the development of this mode of reproduction ranging from that of the non-parasitic bay-wing through those of the completely parasitic screaming, shiny, brown-headed, bronzed, and giant cowbirds. The present report deals only with their host relationships, as this is the aspect of their biology in which our knowledge has shown the greatest increase since the author's discussion was published in 1929.
