First documented observation of Island Scrub-Jay (Aphelocoma insularis) precopulatory display
Cheek RG, Harris ML, Kennedy A. 2019. First documented observation of Island Scrub-Jay (Aphelocoma insularis) precopulatory display. Western North American Naturalist. 79(2):275-279
"first documented observation of Island Scrub-Jay (Aphelocoma insularis) copulation behavior. We compare our observations to the behaviors of other Aphelocoma jays with the aim of identifying potential species-specific elements. There are observable differences between the precopulatory display of the Island Scrub-Jay and that of more distantly related Aphelocoma jays. The display of Island Scrub-Jay and that of the closely related California Scrub-Jay (Aphelocoma californica) are very similar despite the species being isolated from each other for approximately 1 million years."
