interested (he had just eaten a piece of meat at 1:15) came running up, crouched low to the ground, prodded underneath the rock until he got the mouse, ran off with it and proceeded to "kill it again". This was a process requiring about 5 minutes, (although he could have swallowed it instantly) as he lost interest two or three times and stared off over the surroundings. But he did eat it. When the other mouse was put under the rock, Archie repeated Terry's performance even to the point selected at which to "kill" it. There, however, he diverged and struck the mouse only once or twice on the ground before gulping it down. The unusual feature here is really their indifference to food, especially live mice, for so long a period of time, especially as they had had almost no food prior to the observation period, and their prompt acceptance of it when it was presented in a special way. Normally, under similar conditions, the live mice would not have been refused, particularly after they had actually been seized and killed, and some of the meat would have been eaten--certainly some of that offered by hand. The simplest explanation is that they were not hungry enough. On the other hand, both of these birds and big Rhody as well, have often eaten meat that they have seen lying before them for hours and not touched, when I have simply picked it up and offered it to them. Rhody has even eaten meat that he has perhaps stepped on 20 times in 5 or 6 hours when I have merely di- rected his attention to it. Their immediate interest in the dead mice when I pushed them under the rock fits in with previous experience with these birds; yet I was unaware that the act would make a dead mouse more attract- ive than a live one offered in hand. Any object: a stick or stone, a hand, meat, leaf, anything, moved about in a relatively inaccessible position or in partial concealment or as if trying to escape to some refuge, usually arouses their interest at once and they will try
