Holmes, R 1960 Erolia alpina 13 June Barrow, Alaska with one wing raised. The bird was open, & apparently a nut was gone, but the wind was against me for hearing. Later, a pair was seen in the chasing display, but no definitive displays were seen. 14 June - several pairs seen chasing near the ridge plot, Ikravik 15 June - a pair seen going through the chase routine where the "♂" attempted to mount the female, but was thrown off several times. This lasted for about 1 min. Afterwards flew up to display. This took place along gas- line ridge. 17 June - a nut was located just east of the drum area about halfway between the camp & the large pile of drums. It was found in the morning by Warner and contained 3 or 4 eggs. In the evening it was destroyed by an ATC man driving a vessel over it! It was located in a sparsely vegetated area. There were a few pieces I standly grown, but most had been cut by the limning. It was a nut in a moderately developed polygon.
