Our results show that internal incubation gives cuckoo chicks that crucial head start in life, allowing them to dispose of their nest mates - a superb adaptation to being a brood parasite," said Professor Tim Birkhead, from the Department of Animal and Plant Sciences at the University of Sheffield.
Experts agree that any reduction in forest management, including the planting of tens of thousands of acres each year and the control of brood parasite cowbirds, will result in a quick decline of the species.

Indeed, most presumed brood parasite eggs in earlier museum collections, the principal source for many of the Schonwetter's data, were identified only on the basis of appearance and geographical probability, rather than by actual observations of egg deposition.

As the likelihood of multiple substitutions of nucleotides within a site is higher within the species groups that are less closely related and have higher interspecific genetic distances, the values of estimated genetic distance will underestimate the distances between the host species, which were greater than those between the brood parasite species.
The brown-headed cowbird (Molothrus ater), an obligate brood parasite, had previously shown greater resistance to infection with WNV, lower viremia and faster recovery when infected, and lower subsequent antibody titers than the red-winged blackbird (Agelaius phoeniceus), a close relative that is not a brood parasite.
