I went over there and tried to get him to come down. It was found that his interest was held by another thrasher also singing loudly to the east, about 100 yards away, in Reynolds territory. I went over there and the two birds sang more or less alternately for some time. Then the songs ceased and there was scrapping about midway between the two points amongst the bushes. The two Reynolds thrashers continue to return to the aviary for food (and refuge?). B was soon back again at this place, singing loudly from point to point. Bb getting tamer. Bb, whom I have neglected for the last day or two, came to take worms from my hand almost like a veteran. He appears to be in incipient moult.?? Underestimate B's distance. 10:30 A.M. B is still singing full song here. (An error--he is really 250 yards away--and windows are closed.) A thrasher has now been hanging about the Sampsons' for a week or so. The neighborhood is getting attractive to them. Pat attacks snake. About 12:30 Dr. Reynolds brought over a live gopher snake that Pat, true to thrasher form, had discovered at his place and was pecking and dancing about. We put the snake in with the road-runner and the magpies to observe results. The snake was one of the most vicious ones that I have seen, striking fiercely and swelling its head out into a sharp corner triangle, hissing fiercely whenever it struck. The reactions of the birds toward the snake were almost precisely nil, although it must be admitted that they were somewhat disturbed by the presence of so many people present. After they were allowed to calm down by our leaving them unobserved for a time, they behaved no differently.. Still later everything was as peaceful as ever. The magpies showed a little curiosity about the now motionless reptile and one of them approached it calmly to within about 18 inches, whereupon the snake struck, but the bird dodged and took no further interest as long as I was there. The road-runner, reputed slayer of rattlesnakes,
