595 B&G freeze. Autigiro and hawk. On one of my visits to the glade this afternoon, I sat and watched B&G preening in the bushes in fron t of me. They looked up (all but their heads) in the air and froze, but did not retreat, and began talking to each other in very low tones. I looked up and saw an autogiro high up overhead, but the birds did not seem to be looking at it. In about 2 minutes a hawk flew over at about the height of the old oak. Brown- ies then came to me repeating two new syllables, sounding like the high-pitched bark of a very young dog, over and over again: Row-hoo, row-hoo. (The o as in now) always I am convinced that the talk of these birds is not the mere often operation of an involuntary reflex; but that it has a definite intent behind it (however obscure it may be in the bird's mind) and frequently especially that it is intended to convey a message, when it is not imitative. New talk. Believe talk has definite purpose. Speculation on intelligence. With no background in any of the life sciences to guide me, I am unable to attribute the extraordinarily extensive vocabulary of these birds (compared with Brown Towhees for example) to anything but superior intelligence, and if there is a difference in intelligence there must be intelligence there! Feb. 19th. B guards nest(?) Heavy rain during the night and more due. On entering the glade at 8:30, Brownie, the only bird present, flew up to my hand. When I went up to the nest, finding it perfectly dry under its roof, B as usual, came too and popped into it. Although he is undoubtedly guarding it-I think-his attitude is not at all belligerent and he readily accepts offered worms. When I left, he stayed there and uttered a few musical calls. Full song in rain. 9:45 A.M.. Raining, and one of the thrashers is singing full song in the direction of the glade. Song moving about. 12:10 P.M. There was so much song moving from place to place, that I went out at 9:50 to see what it was all about. The birds were
