Child (1957) S. longicaudus 3 14 July Pitneyea River, Cape Sabine, Alaska the 6th. The trap lines in that area have been used by the jaegers, about half dozen Longspurs and sandpipies being eaten. I flushed one who carried trap about 50. The aggressive chasing was directed to parasi[t]t[ic]s also but both species did not seem to respond to it and they flew directly across the area. 16 July jaegers congregate, particularly parasites along the river by our garbage during net, at low ceiling windy days. I noted 2 long tails, one resting against the bluff behind the tent and another a few feet away. The latter was feeding actively on insects or plant material; I suspect the former as the area is one of deep snow and there is little green material there now. I have neglected to note the stomachs of all jaegers collected contained just our garbage. In this matter I have goofed and should collected a series over the tundra. No dark phase bird of this species have been seen. 17 July During the night 4 came in to carbon parts and they made a hell of a noise (squabbling) among themselves.
