NOTES OF DIET IN HIGHLAND SNAKES Rhadinaea calligaster AND Rhadinella godmani (SQUAMATA: DIPSADIDAE) FROM COSTA RICA.

Resumen

I report observations in diet of two species of graceful snakes: Rhadinaea calligaster was observed preying on a salamander of the genus Bolitoglossa; observations are also reported on foraging and feeding behavior of Rhadinella godmani, which was observed feeding on frogs of the genus Craugastor and Isthmohyla. Those food items may be an important resource in the diet of these little-known snakes due to the decrease in amphibian species in Costa Rican highlands.


Keywords.— Graceful snakes, behavior, feeding, predation.
