Some Gull-billed Terns might have rather narrow bills, like this one, but they are still stubbier:<a href="http://www.avesphoto.com/SBB/TRN-20090503_MD_5927.jpg" target="_blank">http://www.avesphoto.com/SBB/TRN-20090503_MD_5927.jpg</a>Sue might be right, it looks a lot like a 1cy Sandwich Tern, which has moulted a bit into first winter plumage, as they have a bit stubbier bills than adults and subadults:<a href="http://www.tarsiger.com/gallery/index.php?pic_id=digimies1189452404&lang=eng" target="_blank">http://www.tarsiger.com/gallery/index.php?pic_id=digimies1189452404&lang=eng</a>However, the entirely white looking tail doesn't fit a first winter Sandwich Tern, but I wonder what it looks like in the other pictures?In addition to the features mentioned by Mark, the translucent white triangle at the middle of the trailing edge of the wing doesn't fit a Forster's Tern too well (but it fits a Sandwhich Tern), and the tail looks too short for both Forster's and Roseate Tern (except perhaps very young juveniles, but they wouldn't have such a head pattern).'First summer' and 'juvenile' are mutually exclusive. At this time of the year, juveniles (birds in their first plumage) are birds that have hatched this year, while first summer birds are birds that have hatched last year.Edit:I too see the Sternula shape of the bird (very short tail, large head), but initially the bill looked a bit too stubby to me. Perhpas it is just the black colour that makes it look stubbier, or could it be a 1cy Least Tern that is coming into winter plumage? A picture showing the upperside of the wings would probably resolve the age question.</blockquote>
