Holmes,R. 1961 Erolia alpina 13 July Barrow, Alaska collected. They were feeding in low polygon -grass area with no water nearby. The 2nd flock consisted of 3 young & both adults. - The young were banded. - These were feeding Nima Pond. Two flocks of RB were also encountered - and 4% wr 15. Few were collared from each flock. These were nearly all molting. All had wing + tail molt. During the past days, all birds seem to have shucked their central tail feathers & Some are molting other feathers for the midline out towards the periphery. Wing molt continues, so that most birds are now molting the 3 or 4th feather from the distal end. Several displays heard today, mostly from the disturbed family groups.
