there was piping from somewhere near nest to which the bird payed no attention. I watched it feeding within 50 yds. of where it landed until 8:30 when it disappeared into the brush in the bottom of the canyon. At about this time I heard a screech like that of a flying bird, but lasting several times as long. I didn't pick up my bird again until 9:20 when it returned to the nest. March 10, 1952. At about 10:30 A.M. I took the ♀ dummy Peggie had made up to nest #1. Arrived there about 10:45, bird already off nest. The eggs felt warm but not hot. I placed the dummy about 12 ft. uphill from the nest, where the bird on the nest could certainly see it. Returned to bird. Due to loss watching I don't know when bird arrived but it (red bird) was there by 11:30, sitting calmly on the nest. If there had been any reaction or piping I'm sure I would have seen it. About 3 P.M. I took the ♀ dummy across the river and placed it next to a clump of grass in the open green flats near the river. For about an hour afterward the children + I were at the river, so there was no activity about the bird.
