October 14th. Brownie sang little, but the bird to the south sang all day again, B not paying attention. Rhody not at his present morning lookout until about 9:30 AM. He filled up on meat at the cage just before noon, resting here until about three. He then followed to the shop-yard, but wanted no mouse offered; presumably all too large, and I had no very small ones left. A Jerusalem cricket was accepted instead. It seems that this was not enough for, after leaving, he came back and waited for something else (presumably). This he did three times so I gave him worms. This again illustrates what appears to be some judgement as to the bulk of the object for which he has suf- ficient "space" left. Repeated visits to the roost tree up to 5 P.M. failed to dis- close his presence, so I resigned the job for the day. (Temp. at 5: 70 deg.; sultry with thin clouds partly obscuring the sun).5:33 For several days now the hawks (Cooper and Sharp-shin, have been back on the job. Their presence is reflected in the behavior of all of the birds, with the uncertain exception of Rhody. Brownie especially is constantly on guard and singing little. October 15th. Rhody was at his lookout near the roost tree at 7:30 A.M., so I suppose he slept in his usual place. Mockingbirds (In the forenoon I made another "motor, listening survey " of other places in Alameda County, finding mockers singing at Centerville, Irvington and Mission San Jose. In the Livermore and San Ramon Valleys there was extremely heavy wind and birds of all kinds had sought shelter. No mockers were heard there). Got back here at 12:30, arriving just before the wind, which drove all the birds to shelter as elsewhere. Rhody had already come for his meat and wanted no mice. He did not appear near the roost tree until 4:15. Then, seeing me, came directly to me for worms. I went and got him a mouse, which he allowed to escape into the bushes before he got interested in it. He then tried his listening tactics, but they did not work. A hawk buffeted the wind above us in a splendid performance witnessed by R warily. The hawk at time was menaced by a humming-bird. Rhody required only 7 minutes to cover his route through the ladder tree, landing in his roost at 4:54. (Temp. at 5 P.M. 74 deg. Sunset 5:33, high wind, clear.). The hawks are almost constantly present now. October 16th. and 17th. Brownie continued to be almost silent, except for talk to Nova and occasional sub-song of fine quality. The other thrasher, to the south, except during the height of the gale which blew intermittently on these two days, maintained his song. Rhody behaved without marked variation from established form,
