Nacled 1967 C. alpina 2 August They are also appearing at the ponds at Shastip Station - both adult and immature. ca. 10 there. 3 August An active flock of about 30 at Shastip station tonight. Very tight flock formation - if they were pectoralis I would say they were about to leave. 5 August About 10 birds w/ 10 melanostratus and ca. 40-50 pusillus near the reefer row, on the East side of the road. Birds were jibbing at pond edge and pond w/ no veg. cover. Collected 2 - SN 799, 800. At Tanglifoot I found another flock of ca. 18 feeding in low polygara- polygara trough, then moved to pond edge. Collected 2 - SN 803, 804. All birds collected today still show light jar. Now molting very heavily. Saw none at Umiat. 8 August 9 August A flock of >100 alpina was feeding around coastal ponds at Shastip Station. Main part of flock - nearly all adults, contrary to Holmes - flew very tightly, but smaller groups fed loosely around pond margins and somewhat on low glass around ponds. Collected 3 - SN 806, 7,8.
