1091 Humming-bird in his roost. Although it is threatening rain, the hummer is back on his roost again. Perhaps he knows best, and it will not rain. tonight He evidently has another roost someplace for inclement weather and I thought he would occupy it tonight. (Calm). November 13th. Hummer was right. Well, the humming-bird did know best, after all, for it cleared up early in the night and the day dawned bright and fair, remaining so. Archie changes the color of the skin on his bald patch. When Archie lost his crown feathers I noticed particularly that the skin was as white as that of a Caucasian of the fair type. I was rather surprised at the time because I had expected to find it dark. Today, however, the very same skin is of the same color as that above his eyes, viz.; an opaque looking purplish slate. There can be no doubt whatever of the accuracy of these two observations. There is no vestige of white surrounding the new pin-feathers. As some of these feathers will become purplish black crest feathers, one wonders whether the feather color is due to pigment and if the change in skin color is due to a "rush" of pigment to this area. It should be noted, perhaps, that the sheathes of the pin' feathers are slaty colored at their lower ends and white at the top. A reverts to hanging nest, out and let Terry take it. Hummer on job. The hummer was on his roost at sunset. A and T eat the mice, The mice that A and T killed yesterday but did not eat, were eaten today by A and, or T. R remembers old roost? Mrs. Scamell says that Rhody occasionally stands on her lawn and contemplates the tree in which he formerly roosted at night as if considering going back to it. November 14th. When I went to the cage in the morning Archie and Terry sat side by side amicably on the perch fastened to the inside of the en- trance door as if waiting for me. It was apparent from a con- siderable distance that there had been some sort of a disturbance previously, as both had feathers awry in their crests and Archie had again lost some of his. Examination of the cage showed no feathers sticking to the wires, but numerous fresh head, neck and soft body feathers strewn about. I found a place on A's neck from which a tuft of feathers had evidently been plucked and Terry's forehead had again been caused to bleed, but the blood had dried and blackened. There were also several of the feathers from the "false wings" scattered about. Altogether it looked like internal dissension instead of a fright from an outside prowler. The tuft pulled from Archie's neck made it look as if he had endeavored to dispossess T at the hanging nest and T had retaliated and from that further strife had arisen, especially bearing in mind that Archie had, at bed-time, last night resumed his interest in the hanging nest and been disposed by me. Still there was no evident bad feeling between them now and, as I approached their roost, both jumped to my shoulders and sat there contentedly while I stroked their plumage, one on each shoulder.
