was no remnant of fear). Julio heard a cat yowling around the premises at a time estimated at 5 A.M. No cat tracks could be found in the soft, damp earth about the cage or on the canvas covers on the roof. (I had already looked for them before learning of the cat). A and T were no more wary of each other than normal. (There is usually a slight tendency for each to avoid too close approach of the other, though at times this precaution is waived). Last night Terry had been reluctant to go to his regular sleeping place, persisting in an attempt to spend the night on my shoulder when I entered the cage on finding that he would not go to bed properly. (We compromised by my taking him bodily and putting him to bed). Speculation leads nowhere definitely. It suggests that there was perhaps a quarrel, also: That A and T are of opposite sex and that their instinct are being aroused. That they are of the same sex and are asserting their claims to dominance. That road-runners are solitary in their habits (Except in the breeding season) and can not get along together when confined in the same cage. That Terry covets the hanging nest as a couch. (He will look at it but not go into it. There was a dispute over it some months ago; first one bird and then the other having possession). No serious quarrel has ever been witnessed between these birds, i.e.: One in which there has been an interchange of blows. On the rare occasions when one loses patience with the other there is one blow and the recipient retreats at once and stays away. In most cases, though not in all, the strategy consists in the attacker seizing the other suddenly by the base of the bill (the tender place). The attacked squawks and flees, and that is the end of it. 7:30 P.M. At bed-time neither bird would go to his regular sleeping place, but wandered about trying one place after another, rejecting them all, except that Terry seemed willing to sleep on my shoulder as usual. Archie would go and sit on one of the principal supports of the hanging nest, but would no enter it. (It should be recorded here that I had shifted this nest during the day time about 18 inches horizontally; without, as I thought, making any conspicuous alteration of its relation to surrounding objects). A few minutes ago I found A sitting on the same support and T on a low shelf. I put A in his nest and T in a new one like it. Neither bird would stay in but would remain perched on the edge. (This new nest was located similarly to the hanging nest, and was decided upon on the assumption that the present disturbance resulted from Terry's attempt to recapture the hanging nest from Archie--a pure guess--and that if T were provided with one like it this source of friction might be removed). Terry's "regular" shelf in the annex was raised about 4 inches to give him an outlook to the west; lack of this outlook heretofore has been the only drawback I could see to that particular location. However, Terry would not even approach it voluntarily
