Colymbus auritus. Podiceps cornutus. 1889. Maine this year I saw L. Umbagog. From the 10th of October to the close of that month Horned Grebes were seen almost every day in the Lake, sometimes in flocks of three or four, sometimes in pairs or singles. When in flocks they usually kept well out in the Lake and were quite as apt to fly as to dive, upon the approach of our boat, but the pairs and single birds were often observed in shallow water close to the shore and not infrequently resorted to diving when hard pressed. They are much less difficult to shoot than the Pied-billed Grebe, but still several that were met with would probably have escaped had we tried to kill them. In no instance did I see one of them take to the grass or to the lily pads as the Pied-billed is so fond of doing. On the contrary when discovered, as they often were, close in shore among aquatic vegitation, they invariably sought to get out into deep water as quickly and directly as pos- sible. Like most of the Grebes they are graceful birds on the water and quick as a flash in getting under cleaving the surface like a knife and leaving scarcely a ripple behind. 14
