1270 the street headed for his roost, but, on reaching the west lot, came back out of the bushes again to stand facing me. (The answer to this was worms. At 4:53, moving 2 or 3 feet at a time and listening intently, he entered the thicker brush near the ladder tree. At 4:55 he jumped up into it and remained motionless for 2 minutes. Altogether it took exactly 13 minutes to enter his roost in 7 moves, the last rest being 4 minutes and the one before 5. During the resting periods he appears to be almost frozen with neck stretched out to its fullest extent in the direction of his roost. The distance covered in 13 minutes was about 25 feet. In roost at 5:08. (Temp. 77, Sunset 5:43). It is probable that his roosting time was delayed 20 minutes or more beyond what it would have been had it not been for the automobiles and my offering of worms. October 9th. Rhody again chose the west lot for his morning loafing period. With considerable coaxing he consented to come down to the street, follow me to the entrance (with one slight detour to peek in at the dog with dramatic poses which left the dog unmoved) and up the driveway, edging by the postman's car, to the shop-yard for a mouse. The last part of his journey of 200 yards or more was made without coaxing when he realized its import. (About 10:30 A.M.) After the mouse he retired to the shade 15 feet from me to rest I sat down to await results. In about 10 minutes he heard a distant sound, somewhat like a cooing (source unknown). He flew at once to the top of a 6 foot step-ladder 7 feet from me and rattle-booed sonorously five or six times much excited. I got the impression that he thought the sound was made by a road-runner, though I did not think so. He sat on the ladder for about ten minutes, nervous and excited, listening and looking in all directions. A hawk (Sharpshin?) flew overhead about 50 feet up. Rhody immediately flew 15 feet to the tool-house parapet, rising 6 feet, as if to observe the hawk better. (Instead of retreating). This was followed by another upward flight inclined at 45 deg. to the pergola supporting the rails on which the observ- atory roof rolls. Thence upward another 6 feet to the roof. (Note the upward flights of which the road-runner is "incapable"). This is the first time for many weeks that Rhody has been seen on top of the roof of a house. Here he remained for 17 minutes surveying all points of the compass. Incidentally puffing all of this time with open bill. The hawk again sailed overhead, but he did not react to it, perhaps not seeing it. (Shade temp. 77). He now sailed down 70 yards to the street 52 feet lower, passing over the tops of the trees. When I reached him he was sitting quietly on the curb, in the shade, with spread wings cool- ing off, with no signs of nervousness and no apparent objective in view. In a few minutes he illustrated one of his very hen-like characteristics. An approaching automobile frightened him, so instead of slipping off into the bushes behind him, nothing would do but that he should dart across the street directly in front of it in order to reach this place. It is interesting to watch the reactions of drivers under these conditions. Most of them have probably never seen a road- runner at such close range, or perhaps ever. They all register surprise and interest; some apply the brakes: some stop and ask
