Machea 1968 C. melanotos 23 June) the evening run of the traps got 2 birds: 913 - a ♂ with a fresh brood patch, and 914 - and app. alpine. 24 June things have quieted down some- fewer birds in the areas of activity yesterday. The birds by IV and X have moved away from the SW flar, and are feeding on WSW flar and low polygon humara ca. 200 m. west of previous area. I collected a territorial adult ♂ below Gasoline Ridge. He is light (SN 918 - 97.6g) but has a well developed cervical region. Feels like all of his reserves are tied up in the cervical deposit. tom reported a flock of 200 to 300 (that's what he said!) in the Drum area. Wish I had seen it "...with my own eyes". 25 June As yesterday - the big fling is over. Still some displaying and squabbling birds, but more flocking. 26 June do ♂. Saw several fairly large (to 60 birds) flocks - some wheeling about in the air. they are obviously getting ready to depart. 29 June the exodus has begun; some birds in Central Marsh, but definitely fewer in the area. Collected 1 - SN 926. I should have a sample of the pre-departure birds.
