West Lot getting too public. About noon a young man was seen lying on his back in the thicket near tree 9. Rhody had disappeared. I went over the fence, entered the thicket and sized up this young fellow, engaging him in conversation a minute or two. He seemed of the "collegiate" type, was courteous and clean. (Later I found he had used papers from a note book bearing upon what was evidently a "business" course. As I talked to him Brownie joined us and came to me for worms. A little later, Mike, the tract gardener, told me he had seen "about 2 hours ago" a boy about 14 climbing Rhody's night-roosting tree. The boy jumped down and made of when he saw Mike. The new road-runner. At 12:20 the new road-runner was in the outer cage. He ran around, on seeing me, trying to find an outlet, and "rattle- boosed", finally taking refuge in the upper story out of sight. No food eaten. At 1:40 R came from his post for food. He had both meat and mouse, returning to his post. (Temp. 63 in clearing). It was not until 3:34 that he arrived at position 1 in the ladder tree. Apparently it was too comfortable at or near his post in the meantime. This suggests that, at this season, one of the elements bearing upon his going to roost and getting up--as to time-of day--is not weather at the time in an absolute sense, but the comparative conditions of comfort which weather conditions at the time offer in two selected locations. That is: assuming his hunger to be satisfied, the time at which he seeks his roost on any particular day, depends upon whether the roost is more comfort- able than the vicinity of his post. This is borne out to a certain extent by his behavior after 1:40 today. Thus he dusted right after eating and started toward the roost, but changed course and went to his post. Twice later he was seen to leave his post, dust, as if going to roost, move toward the roost, then return to his post. He finally landed on his roost at 3:40 P.M. The above theory seems to fit in with those observations where he was seen to leave position 1 and return to the ground to sun himself some more. December 18th. The new RR was not seen to eat during yesterday. He will permit one to enter the cage and stand under him without flying into a panic, but is more or less frozen. At 10 A.M. Rhody was again already at his post. He had a mouse at the fence while a visitor stood about 30 feet away watch- ing. (Brownie took worms from this visitor's hand--Mr. Frost). Rhody's roosting time was not observed, but he was seen to be in his roost at 3:40 as I passed by. This bird was not actually seen eating during the day. The mouse left for him was not touched, but the meal-worms were ap- parently eaten by him. He will be, for the time being at least, designated as R5, that is the fifth road-runner under observation at this place, the others being: Rhody, Circe, Archie and Terry. New Road-runner. R5.
