neither could be found. About 7:50 I called toward the glade and got an answer. Both birds came at the same time and I fed both at once. They than began to pick up soap-root, but abandoned it and loafed around. I went to the nest and, in a few minutes, both came and picked up soap-root from the supply which I had placed on the flag-stone, working side by side. Greenie was the first to carry up a load. They have used up nearly all of it. Work began at 8. The talk while feeding this morning contained few familiar phrases, although Greenie said pit-yurki once or twice. 9 A.M. (Temperatures: Now, 72. Yesterday max. 91, min.65. At San Francisco, max. 92, min. 63. Short periods at these temperatures are to be expected at this time of year, although "everybody" always says: " I never knew... etc...." These figures may be exceeded by several degrees). Another thrasher At 9 the two birds were in the vicinity of the nest and another thrasher was singing in the canyon several hundred yards to the west. I gathered a supply of soap-root bulbs and pulled them to pieces beneath the nesting tree. Brownie, who was up in the nest, came down, gathered them up at my feet and carried them up to the nest. This team-work makes their task immensely easier. Cooper Hawk comes. 10:20. I sat under the tree, a hawk, which I took to be either a Sharp-shin or a Cooper, appeared on the ground about 40 feet away, under a tree. There was one call from a Spotted Towhee, then a great silence as the Linnets and Purple Finches which had been singing freely, suddenly stopped. The thrasher at the nest appeared undis- turbed. The hawk flew as I started for the house to get a gun, but not far, so, on my return I potted him on the last flight he will ever make. I took him to be a male Cooper, length 16 inches, wing- spread 28, but there were four bands on the tail instead of three as described by Hoffmann and there was no bluish tinge on the back.
