Bubo virginianus Lake Umbagog. 1898. As we were paddling down the (Cambridge) river at about Sept.11. 3 P.M. we saw a Great Horned Owl. It was quite as alert and shy as a Hawk, starting from an ash tree that overhung the water when we were fully eighty yards away and flying back into the woods where it alighted on a large branch and sat watching us while we looked at it through our field glasses. Will Sargent tells me that he often starts these Owls along the banks of the Cambridge. He thinks they are attracted by the Muskrats which they prey upon freely. Great Horned Owl hooting in bright sunlight. Lake Umbagog, Maine. Curtis Meadow. 1900. As we (the Stones and I) were taking some photographs, Sept.14. two Great Horned Owls began hooting in the woods to the west- ward keeping it up for fifteen or twenty minutes, although it was early in the afternoon (about 3.30) and the sun shining bright and hot at the time. One bird's hoot was regularly the typical hoo, hoo-hoo,hoo, hoo; the other with equal reg- ularity hooted hoo, hoo-hoo-hoo, hoo-hoo-hoo, hoo. The hoot- of the second form regularly followed that of the first in quick succession; then there was a pause of several seconds before the first bird hooted again. I do not recall ever hearing these Owls hoot in broad daylight in the north before, but it has happened at least once in my experience in the South - at Charleston years ago. 59
