Terry now "pucks". Both birds were more than usually restless today, rattle-bood, brooded and puck, puck, puck-ed frequently. Terry, for the first time noted uttered this last call. Terry also used the backward wing-clap once or twice. Rhody, ditto. This gesture is generally made as the bird starts to run. As a preliminary it jerks its head and tail up sharply, spreads its wings horizontally --about half open--runs a few steps and then slaps the backs of its wings together two or three times, each time returning its wings to the horizontal, spread position and continues to move off with the wings so carried. The slapping is done so quickly that I can not be absolutely positive that it is the backs of the wings that contact. If it is not that, then it probably is that they are slapped on the birds back. (Not sides). A and T answer R. A and T now, unmistakably, do at times, answer Rhody's rattle- boos in kind Rhody has not deserted nest. Rhody has not been seen working at the nest for some time, so after careful scrutiny of the surroundings and failing to see any roadrunners about, I went to the tree. The nest was, to my surprise, more opaque to the light of the sky than Rhody's activ- ities would seem to warrant. More careful scrutiny, however, reveal ed a big tail sticking out at one side, motionless, so now I know that he has not deserted the job. Brownie scores again(?). At 6 P.M. Brownie suddenly appeared near the cage and began to dig furiously and much more earnestly than he has done lately. I headed for the nest in time to see B with something in his bill making for his old passageway under the fence, giving the "blue-bird" approach call. When I reached the nest observation point, the small branches about it were stirring. Circumstantial evidence, considering the lateness of the hour and his absorption in that particular activity, that he has another family on the way. Tomorrow should tell. (By observing what he does with meal worms). March 20th. B undoubtedly has babies. 8:30 A.M. Well, it looks as if the diagnosis were correct. I just saw Brownie skimming about for grub and suggested worms. I got a mild shock when he ate the first two, as it seemed to indi- cate no arrivals as yet, but the next one he prepared carefully on the ground and bolted for the nest, making the blue-bird call. By precedent, this means only one chick, and that very young, that is only one large enough to feed; especially as he did not come back for more. This one, then, on this basis of reasoning, would have been born yesterday. A and T, nesting activities. At 1:30 P.M. Terry was in the west nest crying. I went in and handed him twigs, which he immediately began to arrange, again crying "betwen twigs". Archie noticed this and approached the nest. (The converse of yesterday). I gave him a twig which he took to the nest, joining T there. Both birds then worked together amicably. At one stage of the proceeding Archie took hold of T's feathers at the back of the head, producing no apparent reaction. Shortly afterward Terry left and A continued to rearrange the twigs already in the nest. (This is the first time there has been any considerable coordination of their operations) Terry, now on the ground, kept walking about my feet. I gave him a twig and he began carrying it all around the cage, on the ground, uttering a rapid succession of coots (as nearly as I can get it).
