Pearson 1951-1952 Thurcorn Jan. 10 Saw down young at Hoxley Farm about Dec. 26. Yesterday at Pampas Viscoria 4 p.m. flushed a pair and found them a shallow nest in mat grass. Nest of short pieces of grass, contained 4 eggs, each about 40 x 28 mm, neatly arranged with sharply pointed ends down, speckled brown round ends up. Went back at 5 to photograph but no parents about. Returned 8 a.m. and two were feeding 10 ft. away, no parents, eggs cold although covered with bits of short grass. Took photo. Mar. 9 Saw flock of 30 today (82 km W. Reno, 14,000 ft.) This is the largest Thurcorn. Others of 6 or 7, occasionally pairs. Have heard some of the "flirry" call lately. Mar. 23 A flock of 15 frequently seen or well alone our camp (Tongoa, 14,000). Occasionally hear flying noise. When a flock is nervous and thinking about taking off they give a rather squeaky like an angry Muraton. They also have a rather musical bell-like note. Mar. 31 A squadron fed past Thurco Farm nest #2 at Hoxley Farm alto, some within 3 feet of nest. Many seemed to run from 1 Pyrenphyllum nest to another to feed. Runs like robins or sandpipers, certainly not chimney. Frequent standing on tip-toe and flapping wings.
