Lake Ontario across from the Van Lare Treatment Plant in Irondequoit is a good spot to look for Little Gull.

Charlotte Beach and the Genesee River outlet at Charlotte are good places for gulls, ducks, and mergansers and possibly a Snowy Owl.

Sodus Bay and Conesus Lake usually have good numbers of waterfowl as long as there is open water and not too many hunters.

Lake Ontario can also produce a King Eider or Harlequin Duck.  If you find some Goldeneye, look closely for a Barrow’s Goldeneye.
