Motacilla flava - 3 4 June. Heacle River Coal Mine, 152°25'W, 70°28'N, Alaska are at least two pairs here, probably using the creek as a territory boundary. There is also an odd bird near the CO2 Warrique which may be a different pair. Birds feeding actively in open areas and probably taking small flying insects, jumping up to flycatch to get them. They are always on the move. The tail is wagged up and down but not fanned. Call is a loud, characteristic "tochew", a soft fidget-like "chit chit", and the song, a rolling, rapidly repeated, high pitched phrase: "[illegible]" (oooo) 5 June No signs of them except one on the camp plot south of camp. All are the camp-village area. Saw 3-4 Together once and 2-3 pairs are here. Act like they are starting to nest and they now give a hard, slither-like "toch" when approached, occasionally. Feeding actively, especially by day. Both sexes, if they can be served by plumage, sing as if twice saw dull colored birds in song flight. There is some chasi, and the birds tend to stay in two's when they move about. 6 June Very inconspicuous today, possibly only 4-5 birds about, near the village and near camp. feeding less actively than before. None seen carrying nest material etc., and little song. Be damned if I can sneak up on the citters. 7 June. Only on the village flats, near the village and near camp. 3-4 pairs, probably.
