Freer, H. 1990 June 18 (continued) not seen the snake. At ~1910h an Earthwatch volunteer took to the steps just on the way to the fire station from the lab clearing, where an adult Bothrops asper (~1.5m) was frozen crawling off the sidewalk. Took me several tries to get it hooked into the garbage can, but the snake's repeated response was to crawl away from me. ~2030h Dave & Billie Hardy caught an adult Micrurus nigrocinctus (F, 785+90mm, 7?g, possible eggs palped) active at trail's edge. About the same time Billie saw an ocelot, Felis pardalis, at CES 50. From ~2130-2215 the Hardys & Wendy and I walked on the inundated (~8") boardwalks in the Sendero Cantarana. Saw & heard several Hyla leguami and H. straccatta, a Synbranchus (coming out from under water log), and an adult Leptodeira septentrionalis. The snake was crawling slowly, tongue flicking, w/ its head on the slender branches ~2.5m above the water surface. Tail was not used prehensilely. June 19 Billie Hardy told me there was a brief shower ~0100h, but today was generally sunny. Dave, Wendy, & I walked out SOR, Holridge, Sendero Suampos and the CCL between ~0800-1000hs. We found fresh Panthera onca tracks traveling west for ~50-75m on the SUA ending at ~SUA600 - a stretch that parallels the stream. On a good clear set of tracks I measured the pool as 83mm and
