Fleere, H. 1984 15 June (continued) on his right hand. at 1020h, ≈ CC 1375m, we found a fairly fresh large cat scat that had been scraped over a 6" limb that had fallen across the trail. Took photos. A few meters further towards the station there was a tremendous uproar in the canopy overhead, as we were harangued and bombarded by ≥5 Atles. Orlando returned at lunch w/ 4 bags of cat scats. Soon after lunch ≈1300-1400h, George Schatz (Botany, U. Wisconsin) saw a Spilotes pullatus attacking a juvenile, ambulatory rat near the little bridge on the 50C (≈700 m?). The adult rat was more brown than gray and from the size must have been Proechimys; George assured me it was not an opossum. He first saw the adult rat and at least two young going across the trail, while a third young went to the opposite side, seeming very nervous. As George walked past the rat and a large tree root, the ≈1.5m Spilotes dashed out and grabbed a fourth rat. It chomped the juvenile rat briefly then held it in a body coil, released the mouth and faced George in what he felt was an aggressive stance. He returned to the station for Manuel and Dare, but they couldn't find the snake or the rats. at ≈1900h in show vegetation beside
