Polionetta perspicillata. Maine (Lake Umbagog). 1874. Sept. 17. Saw a flock of fifteen in the middle of the Lake. A heavy north-east storm gathering. 1882. Oct. 9-22 On October 11 five were shot from a flock of seven by George Hayward (I saw the birds). Both this and the preceding species are regular fall migrants. L. Umbagog, Maine.

Although less common than the Butterbill this Duck was seen frequently this season during October, sometimes in small flocks mixed with other species, but usually in company with large flocks of Butterbills. On Oct. 3d I shot five from a flock of 13, all of which seemed to be of the present species. Among those killed, two were adult females and three young birds. I did not see a single adult male this autumn. On Oct. 23d I killed a solitary young bird in the Androscoggin river about half a mile below the point where it leaves the Lake. This individual came from down river flying at a moderate height and finally alighting a few hun- dred yards from us. It allowed us to paddle within good gun-shot be- fore starting to fly. On several occasions I heard Surf Ducks utter the short hoarse quack which I identified when at Point Lepreaux. This is the only note that I have ever certainly heard them make. As a rule I think they are somewhat tamer than Butterbills. Their habits when in Lake Umbagog are in every way identical with those of the species named. 78
