20180917 Caspian Gulls Sheringham Beach




Caspian Gull
Classic juvenile.

Lurked down steps onto beach to photograph a 2nd winter Caspian Gull and came upon (face to face with) this Juvenile bird. Arguably the ultimate juv Caspo shot on shingle...!?
Bare parts: Bill brownish black with paler marbling. Longer straighter and thinner than Herrings with shallow gonys angle. Eye black and set high in head on this bird.
Legs paler pink than nearby Herring with hint of yellow mid tarsus. Longer and thinner with more tibia length also.
Head and body: Off white base tone, whitest on forehead with dense obvious streaking on nape and breast sides. White hanging hind belly to vent noticeable. Small headed and high chested.
Upperparts: Obvious tertial step and solid brown in tone with only white tips. Greater coverts strongly white tipped . Scapulars and mantle moving towards 1st winter with anchor shapes appearing. Striking white rump and black brown tail band seen in flight.
