132 THE CONDOR Vo?. XI preened herself, said "dear, dear," deliberately, and in four minutes flew directly up the hillside and out of sight. At 11:55 she returned and alighted on the pole back of the nest. My presence evidently distrest her, for she gave her call several times and flirted her tail. I moved farther away, but still in sight, when she was quiet, and in four minutes from the time of her coming went to the nest. For one hour and thirty-one minutes after the bird took the nest I sat and watcht it, and when at 1:30 I left, she was still brooding.

In ten minutes an old bird came to a nearby bush, an inch-long green worm dangling from its bill. I was about ten feet from the nest. After giving the plaintive call-note twice the bird carried the worm to the nest. From where I stood I could not see just
