CHILD 1951 Alaskan Wagtail Motacilla flava July 9 Uniat, Alaska These are very common here and extremely noisy. They will follow me for one-half hour flying 50 ft above your head giving their alarm call. Only once was I able to see one on the ground. July 10 Wind does not seem to affect the activity of these birds. They appear to have young off the nest and are feeding young. July 11 They were very quiet & did not continually scold this morning as they have generally in the last 2 days Aug 7 East Armulik, 110 mi SSE Barrow, Alaska I would estimate this to be the most common bird or at least the most conspicuous bird in the area. It appeared to have no ecological preference as it would feed in the willows or on the tundra. They would fly up in alarm giving their alarm note upon our approach but they did not follow us as they did at Uniat. This is undoubtedly due to the facts that the breeding season was over and the lack of adult birds in the area. This latter fact was emphasized after several very thorough searches for adults in a collect of several birds, in various plumages which yielded no adult birds. This seems to be the situation in the tree sparrow as well
