Increased plumage darkness of female Shiny Cowbirds Molothrus bonariensis in the subtropics: An adaptation to bacterial degradation?

Mostrar todas las versiones(2)

The Shiny Cowbird Molothrus bonariensis is a sexually dichromatic species, in which males have blackish-blue iridescence and females are dull brown. However, in some subtropical parts of its distribution, females show a plumage polymorphism that ranges from dull brown to dark brown and even black. P...
