telligent one based on a real understanding the changed conditions? October 16th. Little early song. There were a few early morning calls 7:50 A.M. (Temp. 66) Looks as if it would be a rather warm day. About 7:30 Brownie was calling and singing full-song from the old oak. I stood there watching for several minutes. The theme about which the song was built was the orkit, yerkit, erkit and pit-byouic one. Greenie suddenly called from the nest orkit, orkit, orkit and, without waiting for Brownie, flew up beside him. Brownie left at once for the nest and Greenie continued the song for a time before drop- ping down to me for worms. The interesting thing here is, that if I had not seen the birds, I would not have had any intimation that the singer had changed, so like were their songs even to the phrases used. Testing memory of pitch 2 weeks after hearing call. 8:50 A.M. It occurred to me to again test my memory of the pitch of Greenie's high peer of Oct. 2nd. (It has not been heard since). I fixed the sound in my mind then whistled it, then went to the piano and struck C3 (Counting middle C as C1). This was too low. D was too high. C sharp was too low. So roughly I was about 3/4 tone out, assuming the original identification to be correct. 10:25. A strong north wind is roaring through the pines. (Temp. 78) A steady sound seems to inspire the thrashers to sing. I have had this impression many times. Brownie is sitting in the glade giving many imitations in his under-song. (About 1/2 song). G is in the nest apparently not disturbed. 12:45. (Temp. 86) "I never, etc...." Just returned from town. Despite the noise of the wind in the trees I could hear Brownie's under-song before I entered the glade. He was well wound up, making more inarticulate sounds than usual and more sounds with ells and ens. From a flute-like phrase which sounded like: New phrase.
