DeBenedictis 1964 Feb 18 Punta Suarez, Isla Espanola (Hotel) Galapogos. did not stay at the spot where the other bird had been working. Saw one & taking the beaks of the common low plant of the Blue-ft. colony, and another cutting the green leaves of This is likely their major water source. The two fuliginosa working near here were also digging in the same manner as the conirostris, although they seemed to be less efficient and moved gravel weighing on the average not less than 10 grms. The largest stone I saw moved was lying flat at the top of the pit and was kicked aside and a little down. It weighed 8 1/2 grm. The pit dug by this bird (4 plumaged) was about 3"x2"x 3/4-1" dep. This bird dug quite constantly, while another & plumaged bird nearby preferred to probe under stones and in small pits and only sec. dig a pit of its own. Before working here scraped aside very small gravel and soil with its beak from the base of large corks. A worker here was seen throwing for some 5-10 seconds in the remain of a low wish, before it wandered off. Most of the other workers there were just curious as to what & was doing. (Last night we watched a rookie chasing moths which were flying out from the island from the N). It was rather clumsy and slow flying and did not seem to catch many of the moths, but went 20-30 ft. up into the air after them.). Thad cut the skirt to dry which attracted many flies; a & Tropiderus became much attracted to the flies. She would come out
