Kleptoparasitic behavior was observed by the authors in P. tiliguerta and P. filfolensis. That this behavior has been observed in two mediterranean species of Podarcis, independently parasitizing on species of Camponotus ant, suggests there is benefit to kleptoparasitism on Camponotus spp. in Mediterranean ecosystems.
The Annulated Treeboa (Corallus annulatus) is one of nine currently recognized species in the boid genus Corallus. Its disjunct range extends from eastern Guatemala into northern Honduras, southeastern Nicaragua, northeastern Costa Rica, and southwestern Panama to northern Colombia west of the Andes. It is the only species of Corallus found on the Caribbean versant of Costa Rica, where it occurs at elevations to at least 650m and perhaps as high as 1,000m. Corallus annulatus occurs mostly in primary and secondary lowland tropical wet and moist rainforest and it appears to be genuinely rare. Besides C. cropanii and C. blombergi (the latter closely related to C. annulatus), it is the rarest member of the genus. Aside from information on habitat and activity, little is known regarding its natural history.
We document opportunistic foraging behavior by Caiman crocodilus in a post-inundation forest at Estacíon Biologíca Caño Palma, Costa Rica.
