Maclean 1968 C. melanostris 30 June Collected 2♂♂ (928, 929) from a flock of ca. 50 birds in Central Marsh. 1 July Snow fell today, and most of the flocking birds seem to have departed. Don't blame 'em. Did manage to collect one ♂ (930) from 10 in a flock in Central Marsh. This bird was the heaviest of the year - 107% g not injected. Actually, there are still more flocking birds around than I thought yesterday. Perhaps a 50 % reduction over 2 days ago. 3 July Found flocking birds common along the Gaswell Road - feeding not on the grass, but in troughs and at pond edges. Took samples where they were and where they weren't. The former had things - esp. Pionocera, the latter didn't. Damn clever, these pectorals. The ♀ (940) had a fresh-looking b.p. and no molt; 4 of the 5 ♂♂ were actively molting. Still birds in those same areas along the Gaswell Road. 6 July 8 July A very tight flock of >100 birds in Central Marsh. A random collection of 6 birds (2 shots) produced 5♂♂ and 1 ♀. All of the ♂♂ were molting, but not the ♀. 11 July A flock of ca. 15 dispersed in Holmes' Morass, but more in Central Marsh.
