Machree 1969 Coliornis pusilla 7 June Saw 2 birds feeding actively around a melt-pan in the middle of Berrow Village. 9 June Suddenly they are here commonly and are displaying all over the place. Nearly every bit of exposed tundra has dispersing flocks, with chases and aerial display, and even ground display. A number of these new arrivals are banded - has to be careful to avoid collecting these. took 5-211 1026- 1030. In one case, we may have seen a pair formation. One bird was displaying actively, then flew aggressively at another bird that landed nearby. This bird did not respond, even when the display cockered his tail and gave a burst of ground display. The latter then calmed down, and when the former flew about 20 m. to a new feeding location, the latter flew with it to remain ca. 1 m. away. 10 June Many birds in the area and activity level is quite high. In the drum area the activity level is much higher than the amount of exposed ground would dictate. 11 June Nothing new to report, I think
