Bubo virginianus (?) 1893. Lake Umgagog. October 7. Pine Point. (3) which immediately preceded and followed it. It probably could not be heard at anything like the distances to which the hooting of the Barred and Horned Owls carries under favorable conditions. The whistle is the same as that which we heard near this camp on the evenings of Sept. 26 and Oct. 5 and which we have hither- to attributed to a Saw-whet. It is possible of course that the whistle was made to-night by another bird but if so he and the hooter must have kept close company, for when the latter was behind the tent I heard both sounds in quick succession from apparently the same spot and later when the hooter had moved to the pines on the point near the landing, the whistle came again thrice from that direction and on each occasion the yells ceased while the whistle was being given. If I am not mistaken - and my men have the same impres- sion - this whistle was heard by us several evenings in 1889 and 1890, when we were in camp near Moll's Rock, but the other cries, as I have already said, are positively new to us all. 49
