C. = Cambridge Rive museum Larus philadelphia 1896 Lake Umbagog. October 2② 1907. August 14 flying about on the Calin Offshore Baldridge. 1907 Larus bonapartii D: Umbagog. August 14. A Bonaparte Gull appeared off Salsbridge this afternoon. V during a heavy blow from the N. W. It coursed about over the open water and entered the cove at the mouth of the Cambridge River and then approached the Land closely. It flew near to the town on a height of 20 or 30 feet above the water but every now and then it would drop almost straight down in the bush almost clear of a fern. On rising the direction of the water it would either hover just above it for a moment apparently to pick up some floating object or would alight and swim about, perhaps for several minutes, before taking wing again. It was a beautiful creature, apparently white when seen against the dark green background of the forest, and very buoyant and graceful in all its movements. The behavior which I have just attempted to describe is characteristic of this species of Gull. By it one may form an impression for what it is likely to do soon.
