Uropygial gland volatiles facilitate species recognition between two sympatric sibling bird species
Abstract Visual and acoustic cues in birds have been well documented to play a role in species recognition between closely related bird species. Here, we aimed to test whether chemical cues also play a role in avian species recognition between 2 sympatric sibling species of waxwings, Bombycilla garr...
