scapulars - complex internal markings & mix of colors; wing coverts - simple uniform pattern and color
Detalhes da observação
Continues with flock of resting gulls on sandbar nearest the main observation point into the full tidal basin. The only imm gull in a flock of adult gulls made it easy to locate. Dramatically smaller than very large GWGU sitting in front of it. Obviously smaller then the many WEGUs and obviously larger than the 1-2 RBGUs present for comparison. Roughly length and general shape size of CAGU but w/ heavier chest. Long wings - tips of 4 brownish primaries extend beyond tip of solidly brown tail. Bill uniformly glossy black (pinkish just starting to show along gape of lower mandible), much stouter and w/ obvious gonydeal angle compared to narrower, longish, and straight sided bill of CAGU. 1st cycle gull - much of juvenile plumage on head, chest, scapulars and back have been replaced. The lower body is darker suggesting post juvenile body molt is less advanced in this area. It’s frontal half - the head, neck, and breast are mostly white, and stand in contrast to its mostly dark brownish rear half -ie, the wing panel and flight feathers. Its the face retained a light brown smudging from the base of the bill broadly through the anbehind the eye. Covert feathers in all tracts on upper wing are uniformly patterned: brown with narrow whitish edges that generate a moderately contrasty pattern. The scapulars by contrast are complexly patterned with subterminal anchor and or crescent makings that are varyingly pale brown to dark brown and set against a pale grayish-white background. Feathers on the back are pattered with med brown bars on a similarly pale background. Prominet narrow dark brown bars widely spaced on undertail coverts. Uppertail dark brown. Legs dull pinkish. Iris color is brown.
