Monomorphic ornamentation related to oxidative damage and assortative mating in the Black Guillemot (Cepphus grylle)
The Black Guillemot (Cepphus grylle) is a monomorphic seabird characterized by its muted plumage and bright red feet, which it prominently displays during courtship. Foot color and oxidative stress were analyzed in a Black Guillemot colony at the Bay of Fundy during the 2006 and 2007 breeding season...
