I went to Back River this morning and was able to located one adult Little Gull 
among the large number of Bonaparte's Gulls. I viewed the gull with 
approximately 140 Bonies on the river behind the Royal Farm.  The bird was 
flying back and forth over the water, and the black underwing, and light gray 
upperwing was easily seen.  Barry Cooper also stopped by and saw the gull as 
well before it disappeared (probably further up the river).  By the time I left 
this location, there were over 200 Bonies, 4 Great Black-backed Gulls, about 
10 Ringers, and 2 Herring Gulls on the water and piers.

I then went to Diamond Point.  There were even larger numbers of gulls here.  
Barry had seen a perched Little Gull here (possibly the same one I spotted), 
but I was unable to locate the Little Gull here on my stop.  The gulls were 
more distant, and not really flying around.  Approximate totals at this location 
included over 600 Bonies, over 200 Ring-billed Gulls, and small numbers of 
Herring and Great Black-backed Gulls.
