Male achromatic wing colouration is related to body condition and female reproductive investment in a dichromatic species, the upland goose
Upland Goose (Chloephaga picta) Science Article 1 abstract In many bird species, achromatic plumage patch size can serve as a male status signal, but the use of variations in the achromatic colours themselves as a quality signal has only recently come into focus. In our study, we sought to determine whether achromatic plumage reflects individual […]
