Parasites are widely assumed to cause reduced expression of ornamental plumage coloration, but few experimental studies have tested this hypothesis. We captured young male house finches Carpodacus mexicanus in Alabama before fall molt and randomly divided them into two groups. One group was infected with the bacterial pathogen Mycoplasma gallicepticum (MG) and the other group was maintained free of MG infection. All birds were maintained through molt on a diet of seeds with tangerine juice… CONTINUE READING
