Pearson 1952 notoparota ornata Feb. 26- 82 km W. Puno, Dept. of Puno, Peru. Walking along road, heard 2 perdis, "chips" one chip following close on the other, but the roads come from about 100 yards apart. Finally located, up on the hill, a bird standing with head up - it was in the direction of the calls, although I did not see it give a call. Looked like a ? O? This bird stood very still for a while and then suddenly lowered its head and dashed to the right for the nearest clump of grass and squatted under it. Soon from the left came walking another perdiz who headed for the clump of grass in a leisurely manner. When it got to the grass clump where the first bird squatted, there was a skirmish, with the second bird being chased and then flying 10 yards where it landed at hill behind a grass clump. The original kept running, and passed within several yards of the grass clump but didn't stop. Soon he slowed down and a short while after I heard "chips" coming from his direction again. Feb. 27 From 10-12 watched the nest #1, checked first to see that bird was on it. Sat above it, saw no activity. Bird still there when I left. At 3:30 sat on hill to south of nest, about 50 yds away. Bird on nest. At 4:55 it
