Arthur Nelson Paul Napier R. N. Rosenfield Sarah A. Sonsthagen Sandra L. Talbot Christy Haughey 2020 Although hybrids between captive Accipiter species are known, and hybrids between wild Accipiter species in North America have long been suspected, none have been confirmed to date. However, in 2014, a hatching year Accipiter captured at Cape May, New Jersey, during fall migration, appeared intermediate in size and plumage between a Northern Goshawk (Accipiter gentilis) and a Cooper's Hawk (A. cooperii), and was suspected to be a hybrid. We used data from mitochondrial and nuclear genes to confirm that the hawk was a hybrid female resulting from a cross between a male Cooper's Hawk and female Northern Goshawk. application/pdf 10.1676/1559-4491-131.4.838 en BioONE Genetic confirmation of a natural hybrid between a Northern Goshawk (Accipiter gentilis) and a Cooper’s Hawk (A. cooperii) article
