1097 This freezing habit and more particularly, the non-resistance of the bird when in this state to approach and handling, lends "an air of verisimilitude" to the popular snake-charming stories; but allowance has to be made for the fact that, thus far, these birds have been subjected to such treatment only by a recognised friend- not by an enemy--and that they have for some time been growing more tolerant of handling by me when in full possession of all of their faculties. December 11th. This increasing tolerance above noted has been evidenced by their allowing me to pick them up occasionally without becoming frightened and stroke their plumage. (They allowed this, and, in fact, invited it when very young, but on becoming more sophistic- cated with increasing age, resented it or shrank from it). It has been thought (see back notes) that friction between the young road-runners at bed-time might be a manifestation of the intolerance of adult road runners toward each other, since they are thought to be solitary birds except in the mating season. Somewhat of a set-back was given to this theory when, at 8:30 A.M., both youngsters were found snugly ensconced together in the "house" above mentioned, which is really too small for one. This was a performance unheard of since they were mere squabs. They were calm and unruffled, at peace with the world, Terry behind and partly on top of Archie--not the slightest evidence of antagonism or fear. A half hour later they were sitting side by side on the porch of this house. (Temp. at 8:30, 51 deg.) At 10:20 they were still sitting there, but Terry got down. Archie shrank a little at first as I enclosed him in both hands and considered going elsewhere, but did not. December 12th. to 15th., in… (Notes written on 15th.). B's sub-song. No change during this period. A large part of Brownie's time was spent under the bushes on the warm south bank singing sub- song. No other thrashers seen or heard. A Hawk-Road-runner Incident. On the fifteenth, as I was sitting inside the road-runner cage with Archie sunning himself on the ground at my feet and Terry sitting 12 feet away upon a shelf screened from the outside by glass windows, a hawk was seen to drop down from the branches of an oak about 20 yards to the S.E., hover a moment above a clump of bushes and then disappear amongst the trees. Rhody, who had been getting meat outside the cage, had just retired into this same clump, was presumably still there, and the object of the hawk's interest. Since the hawk (either a Cooper or a Sharp-shin) had left I knew Rhody was safe for the time being, so turned my attention to Archie, who had frozen instantly and without pre- liminaries, although he could have seen the hawk for not more than 3 or 4 seconds. Archie was as stiff as a poker and could not even straighten out his toes when I picked him up and put him on a shelf. Unclasped his fists one toe at a time and set him on his feet. His head, which had been turned toward the hawk, was now in nearly the opposite direction, but still making the same angle with his body. That is: He had not moved it at all while in my
