Feather mites, pectoral muscle condition, wing length and plumage coloration of passerines

Article Abstract:

The feather mite loads of moulting birds were compared with features of new plumage, in nine species, include wren, dunnock, blue tit and linnet. Birds with more feather mites grew duller plumage and had relatively shorter wings than less infested birds. The shape of their pectoral muscle also indicated lower protein reserves.
