Maclean 1968 C. alpina 9 June At 2:20 P.M. - only 2 eggs in the nest. At 3:30 P.M. - still 2 eggs. 10 June At 4:00 P.M. - 3 eggs and being incubated - saw the bird sitting and the eggs were warm. Found two 2-egg nests today - both revealed by flights of a attending bird. The (ca.1600) first - about 300 m. NW of the above nest, on the E. slope of village ridge. The second - (ca.2100) on the S. bank of Wohlslag slough, across from the CRPRL weir. Marked both nests to return and steal the eggs when the clutch is completed. Spent the evening along Elsan bluffs, So. of Wohlslag. It looked like most alpina are in the laying stage now. The tumora has more nest scrapes than I have ever seen. 11 June Again - more of the same. Looked for nest near No. end of traplines III A-B - without success. Nest 1 (No. of IVAB) and Nest 2 (E. slope of village ridge) both had 3 eggs at 3:00 P.M. and 3:15 P.M. respectively. 12 June At 3:30 P.M. went to Nest 1 - now 4 eggs. Bird was off and away, so we went on to nest #2. Collected the incubating bird - apparently a ♀ - and the 4 eggs. Returned to nest #1 and did the same.
