CoEiment 
Sight record al¬ 
most certaiialy 
valid to genus. 
Occurrence prob, 
irregular but 
prob. at least a 
fe¥ every few 
years. 
A few may winter 
on lagoon. 
hypothetical 
because data poor. 
Almost certainly 
has occurred. 
Some of 3 recent 
unidentified gulls 
may have been this 
species or Herr¬ 
ing Gull. 
Probably more 
regular than data 
suggests. 
Two highest bred, 
est imates same.
