Abstract

Corallus annulatus (Northern Annulated Tree-boa) is a little-studied tropical Boid occurring disjunctively throughout Central America and tropical South America in mostly lowland tropical moist and wet forests (Holdridge, 1967; Stafford & Henderson, 1996; Smith & Acevedo, 1997; Henderson et al., 2001). Prior to this report and to the best of our knowledge, small rodents were the only documented prey for wild specimens of C. annulatus (Henderson et al., 1995). Caño Palma Biological Station is situated on the northeast coast of Costa Rica approximately 8 km north of Tortuguero. C. annulatus has previously been recorded from Manicaria forest at Caño Palma (Myers, 1990; Burger, 2001). On 12th January 2002 and 15th July 2003 we found two separate C. annulatus specimens with Rhynchonycteris naso (Proboscis bat) in their stomachs.

Key words:
