a wall. A clear outlook from the sleeping place seems to be more important than physical comfort. This is illustrated in many ways. For example: Rhody sleeping night after night in the pouring rain where the outlook was good in all directions from which an enemy might reasonably be expected to approach, but with a house "behind" him; and in the cage, well backed up, but with head sticking out from behind a wall so that he could command the widest view possible. In the case of Terry before he felt reasonably certain that he ran no risk of being ejected from more ideal locations by Archie, most uncomfortable places would be tried provided they afforded wide outlook and good tail support, such as places fully exposed, against the wire of the cage where there would be only a perch and no chance to lie down. The most ridiculous choice of all--and this made many times during the same weeks of uncertainty--was the upper southeast corner of cage C where there was nothing but empty space! From a perch nearer the ground in that corner he would look longingly up into the corner which is surrounded on three sides by wire only and then fly up into it and attempt to cling there. That he wanted to sleep there was made perfectly clear whenever I would hold my hand like a shelf in the corner. He would immediately fly up to it, fluff out his feathers, get his tail properly adjusted against the wire mesh and settle his warm belly upon my hand prepared to spend the night, right there. (For many reasons unnecessary to give here, I did not care to do the obvious thing and build him a proper resting place at that point). September 10th. Early morning song from Brownie followed by sub-song for a large part of the forenoon. 12:20 P.M. About noon I could not see or hear B, so looked him up. As I approached the dormitory tree he could be heard singing.
