Acanthu havemanni 20 June Mleacle River Coal Mine, 157°25'25", 70°24'N, Alaska Birds near Camp finally really coming, down to feed. Heard them near the village also. Two feeding near the coal mine on a sandy flat. When approached they are quiet. A f? probably by plumage, the 3 brighter and clearer marked than the 4, and shown, here when they get close together. Later a 3rd appeared and the 7 closed it for several minutes. Singing here heard in the willows directly across the mine. 21 June 5h71 around the mine, and across the river. and much singing. 3 birds seen together. Evidently this is a late breeder. 25 June A 4 collected had a well developed (but poorly calcified) brood patch, but was long away from laying any eggs. No sign of regurgit or pellets. The crop contained several small [illegible] slightly hairy diptera, larvae, ? gleaned from the mud under the willows along the river, when they are feeding. The 8's singing loudly. but the group seen - 5+6 - was quite social. The bird collected was a dark bird with streaked upper tail coverts, nearly plain lower tail coverts, and strong flank streaking. Theirs were much clearer, lest the one it "shot" flew off when I picked it up. 26 June Occasional near the coal mine and across the river. 8's singing loudly now. They have a odd raucous buzzy phase which I have not heard from recipalls before - but they are 15 breeding birds I have seen.
