Parental care does not vary with age-dependent plumage in male Saffron Finches Sicalis flaveola

The status signalling hypothesis states that conspicuous male plumage varies among males and serves as an honest signal of male quality and competitive ability. We expected immature-plumaged males of the Saffron Finch Sicalis flaveola to feed their incubating mates and nestlings and remove faecal sa...

description The status signalling hypothesis states that conspicuous male plumage varies among males and serves as an honest signal of male quality and competitive ability. We expected immature-plumaged males of the Saffron Finch Sicalis flaveola to feed their incubating mates and nestlings and remove faecal sacs at lower rates than those of mature-plumaged males. We also predicted that females paired with immature-plumaged males would compensate for their mates' lower contribution. We found no differences in either feeding rates or sanitation rates between immature- and mature-plumaged males.
