Overview

Female smaller. Immature resembles adult, but feathers with less gloss; wings and tail browner, but this characteristic may be of limited use in the field. Fledglings plumage is "ragged" looking, with white showing through from the bases of the feathers at numerous locations on the neck, back, and breast. Lower mandible near base has pink-tan showing
