1318 looking up at the top of the fence, crouching as if to spring up to it, abandoning the effort, looking up hill along the fence toward the hole, walking part way toward it, coming back and pre- paring to jump up, and so forth. Either route enables him to at- tain his objective, and he may take either, but there is an increas ing tendency to come over the fence. If that is his decision, he leaps up to the top, using his wings and sits there for as much as a minute sometimes, before dropping down on my side. If he selects the hole, he comes trotting down through the sage promptly. During all this approach from C he may or may not raise and lower his crest and show his colored skin-patch, and he may rattle-boo, though usually not. Now that he is inside with me he is very calm and deliberate unless extremely hungry, when he rather rushes things. Typically he places himself in front of me about six feet away and seems to listen respectfully while I talk to him and display my wares. He glances sidewise at them, then often up at my face. (I am crouch- ing with the food in hand). It may be a mouse, a lizard or ground- up meat (Hamburger) pressed into a roll about 3" long and 3/4 to 1" in diameter. Any one of them alone, or sometimes a mouse and meat simultaneously in hand. (The mice are usually tame enough to wait in the hand until Rhody is ready to eat them.) Rhody's reactions differ for each of the three offerings. (I am omitting here an extremely interesting reaction to mice based on their size and his appetite at the time, because the observations pertinent thereto were not made during the period under consider- ation, and would moreover, complicate the present discussion). (3) How does Rhody react to each of the three offerings: meat, live mouse and lizard? I.e. typically, not necessarily always. Meat. He approaches quietly, without nervous display, may "cry" or say "ook, ook, ...", takes the meat and if not too large, gobbles it at once, where he stands without retreating, then moves off a couple of feet and "rests" indefinitely after vig- orously wiping his bill. This bill-wiping may be renewed every few seconds, at longer and longer intervals for several minutes. Between times he suns, and/or preens, and/or stretches and/or/or strolls about near at hand "looking at things". (All this is radically changed in mating time). Live mouse. He now seems more like a wild creature, as if the sight of living prey aroused predatory instincts. His approach is more cautious and furt- ive, he appears to sneak up, ooks more, snatches and falls short frequently, he may flirt his wings, raise and lower crest and display colors, finally he snatches it and retreats farther and faster: from 3 feet to 30. If very hungry he gobbles it without slapping it on the ground, otherwise (also if it is a big one) he slaps it. He then swallows it, stands very erect and still for a minute or so, then further behavior as above. Lizard (live). Similar to mouse, but a new element in- troduced which resembles cat-and-mouse behavior. He does not kill it at once, but liberates it, waits for it to run, walking about it "pretending"
