Greene, H. 1983 19 June (continued) firica just S. of la Selva. Went by way of Near Loop, Southwest Loop, and West Boundary trails. Saw guans or curassows. at 0925h found a large & Pseustes poeciloptus lying still in the sun across a cow path on the firica (trees all around on firica, and forest edge <50m away. Met Manuel Santana at ~1030, had snack and coffee, then walked ~20 minutes S. into forest to see where he has a 3m long Boa constrictor, telemetered. Got chased by a bull twice, coming do and from the forest through the firica - it stopped each time when we climbed up on highsteps. Left at 1345h and walked back alone by way of Sendow Jaguar and the steps on the new property, stopping for a swim in the Rio Sarapiguí. On a rock beside the rio found scattered crustacean parts, including two apparent hands ~1cm in diameter full of nothing but such parts - I presume these to be of Lutra longicaudis. Returned to station ~1530h, where D. Leaver (U. Wisconsin) told me he and Rafael Campos found an adult Phleiscerus eating a frog [Eleutherodactylus minius] at 0945h, lead first. Frog was alive when regurgitated and at noon but dead at 15#0h and quite smelly
