Dormilona

Corallus ruschenbergerii is one of the largest members of the genus Corallus with adults reaching up to 2 metres (6 ft 7 in) in total length (including tail). The colors are typically shades of yellow, brown or gray, although populations on Trinidad and Tobago are often a patternless pure bronze.

Corallus ruschenbergerii is found in Lower Central America in southwestern Costa Rica (south of 10° N) and Panama, including Isla del Rey, Isla Contadora, Isla de Cébaco and Isla Suscantupu. In South America it occurs in Colombia east of the Andes, north of the Cordillera Central and north of the Cordillera Oriental, northern Venezuela north of the Cordillera de Mérida and in the drainage of the Río Orinoco, north and west of the Guiana Shield, east of the Orinoco Delta. It is also found on Isla Margarita, Trinidad and Tobago. The type locality given is "Panama".

The primary diet of C. ruschenbergerii consists of rodents (such as squirrels, mice and porcupine rats) and other small mammals (such as bats, mouse opossums and introduced Javan mongoose), as well as lizards, frogs and birds.

The specific name, ruschenbergerii, is in honor of William Ruschenberger, who was a United States Navy surgeon.
