All:

Ronnie d'Entremont has sent some nice images of of a Lesser  
Black-backed Gull obtained Jan. 18 at W. Pubnico. I've placed one of  
these at the end of the Gull-Terns folder NS-RBA photos.

The bird appears to be noticeably dark-backed compared with our usual  
subspecies _graellsii_, and might be a candidate for the n. European  
subspecies intermedius, which some think represents a cline (a zone of  
intermixing) between _graellsii_ of UK and s.w. Europe and the almost  
black-mantled n. Scandinavian subspecies _fuscus_.

Cheers, Ian
