P. DeBeneeld 1964 Feb 14 Punta Suarez, Espanola (Wood) Island, Galapagos. object against a rock on the ground. It took about a minute and a lady to produce an edible luat. A mole conirostris I watched easily kicked up a 20.5 gm. rock. Many small rocks it picked up with the bill and threw aside (one such rock weighed 13 1/2 gms). The habit of picking up rocks may perhaps be something of the origin of tool using. It had dug a hole 1" deep, 2" in diameter when it tries at this spot. I saw one juliginosa allways trying to feed in this manner but it was not too successful and gave up after about 30 seconds. Took a poor picture of a "4" conirostris in the act. Also I saw a mocker with the tail end of a Tropidurus hanging out of its mouth. I ran over to get the lizard but the mocker had already swallowed it. I would guess the lizard was about 5" long. A 8" ? on a rock near where a mocker was feeding kept an eye on the mocker, but ??? not bothered and did not move because of the mocker, which eventuall moved away. Before dinner Ortiz and I dis- mantled the net, which had taken nothing else. I thought the mockers knew what was going on for they ran under it as soon as I got it off the ground. There were 2 other pairs in the area of the net in addition to the birds I took. One birds I was watching, flew, stopped, called a soft "tir-ruck-tiruck" several times raising its tail and tail
