Holmes,R. 1961 Erolia fuscicollis 4 June Barrow, Alaska While driving along the old weasel route, south of Button's Area, a Semi-pel scound up & kept moving along in front of me. Suddenly a second bird appeared next to the Semi-pel & went into a courtship posture. Subseq. both birds were collected (1078-1079) & the display turned out to be E. fuscicollis - The display was the same or seen before, that is with the tail raised but not spread. Wings held horizontally & a slight feet. The weasel noise drowned out any sounds which may have been emitted. I presume the Semi-pel flying hard along the whin must have set off this behavior. (The display looked only 30-35 sec, after which time both birds began to feed - about 6-10 feet apart. 10 June - In the morning, a displaying bird was seen hovering above the tundra at a height of 30' - given the primary rec-over. This was in Heaton (ridge county) - No.1 Traplines ID A&B + Vol's Area (new edge- with a stick psyching out). The bird flew down along the ponds - the lowlands where he was through displaying. In the evening, he was heard displaying twice & he was feeding with a second bird near Pross - so he was noted.
