Steppe Gull barabensis 1CY, October 29 2012, Goa, India. Picture: Paul Ian Holt.For many more images, see the galleries on Flickr by Paul Ian Holt. Illustrative example bird showing moult timing and extent of this species in October. Typically, as a breeding bird of the steppe belt (versus birds from the tundra belt higher north) there is extensive post-juvenile moult in scapulars, but also in wing-coverts and tertials in many birds. Barabensis occur alongside heuglini; barabensis the early hatching species from southern locations. As a result, by October the plumage looks more worn and moult is more extensive. Bird below still showing relatively neat and fresh plumage, with pale tips on coverts still in good condition. |
