Zonotrichia albicollis. 1895, September 10. copy ① Lake Umbagog. Jim and I started off in the hunting boat at 8 A.M., crossing the lake to Richardson's Carry, which we reached just as the fog began breaking up. About midway of the passage we came upon a White-throated Sparrow floating dead on the calm surface. It occurred to me that these birds which we find drowned in the lake after foggy nights may meet their fate by descending through the fog at daybreak and striking the water before they make out what it is rather than by wandering about in circles until they become exhausted. This idea was suggested to me by the reflection that the color of the water when it is calm and enshrouded in fog is precisely like that of the fog itself. Looking down at the lake from a slight elevation I find that I cannot make out the water at all through the fog unless it is agitated by the swirl of a fish or by a breath of air.
