Wales plus 1974 Journal 15- Gardner Bay, Isla Espanola Galapagos, Ecuador 26-27th in the Cryptocerus & scrub we started seej singles. In the early morning hundreds came out to feed along the beach. We caught at least 50. Geospiza conirostris, G. fuliginosa & Certhidea olivacea, are the most common. G. fortis is present but rare; we caught only also lizards & flycatchers & warblers, call in light #1's. Could it be that the absence of rats correlates with the high # of birds? Found that clearing large thick brush worked well. The Tropeken here are very large adults, ~8". They are sweeter than the ones larger on San Cristobal (~5"). Abundant & easy to catch. We made 2 per 15 in less than 30 minutes. They were present everywhere we went, in trees & on the ground. We did not go far inland, however. Tegestids are also abundant. We were setting hard in the early eve to catch 15, in leaf litter, among rocks. When we arrived back at camp Wright showed us literally dozens, far from rocks, in the vegetation along the edge of the sandy beach. After that there were many too small beetles in the sand (similar to those on Santa Barrington but less dense); perhaps this co-occurs itself. Few variegated iguanas, lots of sea lions. Perhaps 30-40 adults.
