1983 5 February (continued) Caught a gravid Natrix capsitis on one of the logs, took photos of her. No new Felis once tracks on the Swamps Trail. Went out to ~1000m on Holdridge Trail, then back to station just before noon. Bird group here saw no snakes today either. at 2140h a bird watcher came and told me he watched a black and orange "coral snake" cross the sidewalk, supposedly w/a fairly blunt tail like Micrurus spartitus. 6 February Saw Rob Colwell off. Left by myself ~0900 for the Lachesis sight by way of the Camino Circular lejano. No snake, no Felis once track in Swamps [NB: the old tracks were going east on trail]. Took a short cut between the Successional Plot to the Sabalo Esquina Trail, then out to 2000m. Check the Bothrops stump - nothing. Saw two large Rhinoclemmys resting on a large log in sun over the creek. Too way for pictures. Returned to station ~1115h. One of the birders had seen a little Leptophis, "large green head w/tan body; one a black snake ~0.5m long w/ longitudinal yellow stripes". At lunch Fernando told me of finding several scats on a trail just inside the new property, so from 1300-1430 we walked out the Camino Experimental across the bridge at LOC 50 and ~200-300m down the trail onto the Vargas tract.
