3 Bubo virginianus. Lake Umbagog, Maine. 1897. length of the legs when the bird started from its perch, but Sept. 7. it always drew them up out of sight among the feathers before (No. 3). it had gone many rods. The wings were usually flapped stead- ily and continuously for the first thirty or forty yards after which the bird sailed the remainder of the way to its chosen perch. The husky cry was often given on wing especially when one of the Owls was approaching a stub on which its companion was sitting. It is evident that this cry is used chiefly if not wholly as a call note and I fancy that whenever it is heard it is safe to assume that there are two or more birds hunting in company. On the only previous occasions when I have seen the bird utter it-at the Lake House many years ago and near the mouth of Cambridge River last October-it was accom- panied by a companion. Altogether we had the Owls at Whale Back Creek under close observation for fully half-an-hour. They worked around us in a half circle following the line of stubs but frequently turned back and went over the same ground. Most of the time they were within 100 to 150 yards. We could see them very distinctly against the sky. : : ---- 56
