White-collared Starling

White-collared starlings are dimorphic in adulthood, with sexual differences in both size and coloration. Adult males have a glossy-black plumage save for a white patch on the chest which extends up to the wings; their bill and legs are black and a bright yellow iris. Adult females are primarily grey with black-tipped wing and tail feathers; the feathers on its crown and rump have blue-black tips. Juveniles and subadults tend to resemble the female, but with more brownish-grey feathers on their ventral plumage.
