February 1952 Tinamotis pentlandii and circled around. There may have been a slight amount of feather shuffling but not much. After about 3 or 4 circles the tote-a-tole developed into a chase up the slope to the north. Lost one bird during the chase. The other stopped when about 200 yards beyond the nest and started calling again. Called for about 2 minutes, then sat on top of the rock for at least 5 minutes, preening occasionally "H" then moved while I was looking for the other bird and so I lost "him". Spent considerable time trying to relocate them and curing the telephoto tripod. Next watch by M.K. Returned another bird at 4:50 p.m. Bird on nest. Started moving about 5 p.m., too snowy to see nest at 5:15, so left blind and set 3 steel traps. Visited nest #1 at 11 a.m. 6 eggs in nest: 3 intact and 3 broken open on top side, still some yolk in them. Two completely broken and empty shells 2 feet from nest. No tracks. March 30 Watched nest #2 from 11:30 to 2:30. Bird on all time. at 1:15 a squadron of thrushes fed past nest, many within 3 ft. of nest, one within 1 foot. Bird on nest ignored them by preening and nest construction. Pulled several feathers and added to nest, at least one of them from beast.
