taking the night shift. The road-runner was sleeping on the shelf, made for that purpose, with his tail cocked up against the wall; an attitude taken, I think, to keep the magpies from sneaking up behind him and pulling it. The magpies were side by side up in the "pent-house", also provided for their special benefit. June 26th. Almost invariably when I visit the nest, no matter how warm it is, the young birds are being hovered by Brownie—occasionally Nova. I get the impression that this differs from precedent, but cannot tell without checking back. It also seems that there is very little feeding going on. In fact, such is the case during the 5 or 6 hours in the middle of the day. During this period the young do not seem hungry. June 27th. Movie of nest, Scene 1. At 11:20 A.M., Brownie on the nest, I took a moving picture of him, i.e. it would have been a motion picture if he had moved. He did not like the camera 2 feet from his nose and froze. (Dis. 2'0"; Footage 4½; Stop f,2.8 (deep shade); Speed 16 frames; Panchromatic film. There were high lights of direct sun, but mostly dense shade). Scene 2. At 11:50 A.M., B on nest, conditions the same, except young had just been fed by me, and larger stop used. (Dis. 2', stop f,3.5, footage 7). Scene 3. At 1:15 P.M. Nova was on the nest, but departed as I went up to it, scolding, first: like a Brewer Blackbird, then very much like a Bullock Oriole—a sound which I have never heard from any thrasher before. Brownie was seen approaching about 25 feet away, carrying two very large spiders, or else Jerusalem crickets and I hoped to get a camera staring him in the face. (Dis. 2', stop f,3.5, footage 6). He would not "loosen up" as long as I was there. The young. These two youngsters are not very friendly—an inheritance, perhaps,
