Very nice, thanks for posting. I also recently returned from spending several weeks in Costa Rica. Pictured above is one of several Bothriechis schlegelii I found in Cahuita, Limon.
Further herp sightings included a young Boa constrictor imperator catching and swallowing an adult bronze-backed climbing skink (Mabuya unimarginata), numerous iguanas and other lizards. Pictured below is the Boa c. imperator swallowing the skink.
