1225 llth., and was not seen at all on the 12th.; not even at any of his three known posting places as late as 7:35 P.M. Brownie, on the other hand, is staying at home more and sing- ing oftener. He has long periods of soft quarter-song and has resurrected his xylophone attachment with its clear, glassy tinkle. His full-song is still not at its best, being rather staccato and, at times, inclining towards stridency with jay-like calls imperative in effect. It contains unfamiliar phrases, one of which can be approximated roughly by: Picky-yuri, or Pickyuni, or Picky-oi-ri. July 13th. 2:10 P.M. Rhody made his reappearance at 10:45, announcing his coming by a soft woo somewhere behind my back where I could not see him. However, in a few moments, he was seen entering the cage for a piece of meat. When this was disposed of, I invited him to take a young rat, which was gobbled without ceremony. After this it was necessary to spread-eagle in the sun, since it was too warm for the open-bowl type of sunning. This was followed by resort to the shade to neutralize the effect of the insolation. When he finished panting there, more sunning followed and so forth, then preening and general loafing. At 2 P.M. he was preening in the shade about 75 yards from the shop, but, on invitation, followed me closely into the shop, where I offered him a young rat. He merely looked at it and from it to me, as if to say that that was not what he wanted. He then went out into the shop-yard where the mice are kept in a large can on top of a stand about 3 feet high. Although he can not see what is in the can, he has been accustomed to see me open the lid and fish out a victim for him, standing quietly looking up at the operation. He now went there and stood patiently looking up at it. I took this to mean that he wanted a mouse instead of a rat, but, as a test, I took the young rat that he had just refused, and pretended to take it out of the can, laying it at his feet. He again refused it, hrooed softly and continued to wait patiently for something or other. He watched me remove the cover of the can (a long job, as it was stuck and required hammering) without moving from his place. I took out a mouse that was slightly larg- er than the young rat and placed it beside the latter. Rhody came forward almost at once and took the mouse, squeezed it and swallow- ed it while it was still alive, as evidenced by the fluttering of the feathers on the bird's throat. Rhody now prepared to take it easy, but, catching sight of the chipmunk, chased it under the regular pile of boards from which it escaped while R's back was turned. R next caught sight of a humming-bird feeding on gladiolus flowers about 10 feet away and proceeded to stalk it, belly to ground, but making no final rush to catch it. His next move was to get a drink. I left to make this note. All of the foregoing action within a period of 10 minutes. The episode with the rat and the mouse bears more than a mere superficial resemblance to an act of intelligence in which the bird managed to convey to me its undoubted preference for
