Comments P.R909 right column 2nd paragraph: "Currently, research suggests that obligate interspecific brood parasitism arose seven times independently during evolution. This includes three origins among cuckoos, and then one origin each in cowbirds, honeyguides, estrildid finches, and a South American duck. Brood parasites are often used as model systems for investigating evolutionary arms races and coevolution in the wild."
