Lake Ontario across from the Van Lare Treatment Plant in Irondequoit is a good spot to look for Little Gull.
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. Conesus Lake is another good spot for waterfowl until it freezes.
