Another New Lifer at Lake Ontario!

As I mentioned on Sunday, I travelled up Lake Rd. which mostly looks like this between Irondequit Bay and Mill Creek:

Up and down winding hills that all look the same, with woods on the south side and lake and stupid mansions on the north side. I located the pond and there weren’t very many birds at all – a mallard pair and a couple of geese:

So I went up to Mill Creek, which runs into Lake Ontario, and saw a bunch of Mallards. Nothing new here either, but it was fun to watch them preen:

Then I walked down to the lakeshore, and saw some gulls floating around in the water. Ring-billed gulls. Got ’em already:

Then I saw some gulls on this pipe thing (what the heck is that anyway)?

Great Black-backed Gulls (Larus marinus) – Mon@rch is almost positive this is what these two birds are! Can anyone confirm this?  According to All About Birds, this is the largest gull in the world.

Thanks again Mon@rch for your help! I’m off to buy Sibley’s Birding Basics and Sibley’s Field Guide to Birds of Eastern North America.  I’ve got a lot to learn.
