appeared on north side of nest, stood very still watchi; me. Feathers on top of head very flattened, neck pulled well in, it looked quite female-like. It took a few tet-tate steps, jerki; head backwards about 20-30 times. Neck stretched out, went offest, looked more male-y. Walked down the alley, watchi; me. The first batch of richer it put its head down and ran about 10 feet behind grass claps. Closely watched nest for next hour and half but bird did not return. Sun set at 5:35, a cold wind was blowing, although t° was only 44°. Dark at 6:20. About 4:15 a llama + a shepherder + puppy passed right over the nest, but the bird didn't flush. Some of the llamas stepped within inches of the nest, one ziped over it. The shepherders was in the rear and walked within a yard of the nest. Dec. 28. About 10:30 A.M. sighted a lone falker on green flats by river. Deeki; in a deevatory fashion, walki; about 12 steps between pecks at the ground. Soon headed up hill with more determination. Went some 150 yds. up hill, disappeared. Searched the area for nests, but could find none. It looked like a male.
