Physical description Click here for a physical description Spotless Starlings are about the size of a Common Blackbird. The two sexes are alike, but their plumage varies between breeding season and eclipse. In breedingplumage they are glossy black with purple and/or greenish hues, depending on the infalling light. There are no speckles. During the breeding season there is one detail that distinguishes between the two sexes: The bill of males is yellow, with a blue-grey base. Females have a whitish base to the lower mandible. In eclipse both sexes are duller black, with inconspicuous dark-grey speckles. In eclipse the bill of both sexes is dark-grey. The irises are dark-brown. The legs and feet of both sexes, are greyish-pink in eclipse and bright-pink during the breeding season. Juvenile Spotless Starlings are all greyish-brown.
