A 1cy Black-headed Gull moulting to juvenile plumage (pre-formative moult). The mantle, scapulars, tertials, lesser- and median coverts are dark, chocalately, brown with a light fringe.
The greater coverts are predominantly gray. The head and throat are patchy brown, while the breast and flanks are buff-coloured.
This individual is begging food off of one of its parents by assuming a hunched (submissive) posture in which the neck is withdrawn and the headed is tilted upwards.
