Motacilla flava -4 8 June Meade River Coal Mine, 157°025'W, 70°029'N, Alaska About two pairs active south of camp, flying back and forth along the river and landing on the willows. Not much sing. 3-4 birds around the village, going out on the village flat and ridge. When a peregrine falcon flew over, one flew up, calling excitedly, and "mobbed" ineffectively the falcon. 9 June 1-2 pairs active about the village. Can't tell while going on, but they are spending time in the old sod house foundations. 10 June Active in the village. They yell at you when you get near them, a whining "weeat!". Saw a female with a bill full of ptarmigan feathers near the 1/4 stakes of the cerns plot, but she was very upset by my presence and eventually tore the feathers up and flew away. She was banded on its left foot. In the evening I was attacked by a longtail and when getting food I saw her fly into a nut. The nut is of grass, partly domed, and unribbed. Once this bird landed near by. The I came out and went in to a very fluffed posture, until the leekap, which was intensified when the other bird approached.
