Juvenile Yellow legged Gull Hayle Estuary tuesday.

 A classic bird and a good opportunity to note some key features,note the deep heavy based bill with a pronounced gonydeal angle and hooked tip,long looking rear end and long legs, it was a brute of a bird so presumably a male.
 The neat black tail band and white upper tail coverts with internal blackish markings stand out well here as does the paler head with the dark eye mask.

 The dark brown tertials with neat fine pale edges are obvious in this shot.
 Note the lack of an obvious pale window on the inner primaries and the white edging  to the wing coverts giving it a scaled look.

The under tail coverts ,white with widely spaced black barring show well here.
