Black backed Gull in Marie Curtis

[Ally]

I found him by the lake of Marie Curtis, went to look for snowy with no luck. But there was also a racoon being eaten inside out, only the tail revealed what it used to be, don't want to disturb anyone with the photos

I presume that your excellent captures are of a pair of Lesser Black-backed gulls.
I don't even know if we get Greater Black-backed gulls on the lake.
Someone spotted the same species of gull at Humber Bay East while I was there looking
for water-fowl. I'm really not knowing my gulls so I never thought to look for them.
Spotting a Snowy at Marie Curtis is unlikely cause most of the Snowy owls must be near Kingston
fighting to get into one of those famous rosy-coloured photos. It's just about as good as it gets.

The best way to distinguish between the two is look at their legs - Lesser has Yellow legs as opposed to pink on Great. Also Lesser has more streaking on head and neck.

I found one pic showing a bit of his feet, kind of pink. And another gull possibly to be his mate, because it's similar size. And he swam towards her and followed her for a bit.

Yes, these are Great Black-backed Gulls. Size difference is good indicator if you have Herring Gulls to compare with, Great Black-backed Gull is much larger while Lesser is slightly smaller than Herring Gull. Also the bill of Great BBG looks massive. Great BBG is more common than Lesser BBG on the great lakes. Both are mainly seen in the winter half of the year.

Thank you so much Thomas. Yes, that gull is much larger than the ringbilled in the lake.
