During my annual fishing expedition to Seyon Lodge in Groton (Noyes Pond) I spotted a pair of super-friendly Common Loons. Noyes Pond is on the small side-perhaps a half mile in greatest dimension. This state-owned property allows only a half dozen of their own, oar-driven boats on the pond for fly fishing for brook trout, which are abundant. By necessity the loons are often 50-100 yards from a boat and seemed to be perfectly at ease. I saw no evidence of nesting behavior.
Other birds that I noticed between fish: Belted Kingfisher, Ring-necked Duck, American Black Duck (family), Canada Goose (family), Common Grackle, Tree Swallow.
