the twigs from the ground she would not even look at me. A worm tossed where she could not ignore it was hastily gulped and a twig immediately seized and a dash made up the branch to the nest. Greenie is but slightly less preoccupied than Brownie. He will look at me occasionally between trips as if expecting a worm, but will not put himself out to get it. During this period they made from one to two trips per minute to the nest. The main branch leading to the nest starts from the ground. The present procedure is to run up this at full speed; no more inspection of obstacles ahead and deliberate selection of the easiest path. While the route has, in general been standardized, some divergence is at the terminus is made at times, in order to reach directly some other portion of the nest. On these detours minor obstacles are encountered, and these the birds go through by main strength, often losing both their twigs and their balances in the process. Very hungry. 9:15. At 9 o'clock both birds came into the glade, when I called, from the direction of the nest, both very hungry. Brownie again had new talk, this time of flute like quality conforming very closely, according to my ear, with our music scale in that I could detect only full and half tones. This is it: Between phrases as above there was a "filling" of thrush-like notes. When finished eating, both birds picked up material and departed for the nest. (Temp. now 75, minimum during night 66. The official Weather Bureau maximum for San Francisco was the same as here, 88) 12:30 P.M. I went to the nest at 11:30. Evidently the most arduous part is done, for the birds were carrying up ribbons from the soap-root. They worked at this until 11:50 and ceased abruptly.
