Boas, Mussaranas and Red-Eye Tree Frogs

Night tours at El Remanso are lead by naturalist guide Rinaldo. The tour starts usually at 5.30, once the sun sets over the Pacific Ocean down here in the Osa Peninsula. Commonly seen wildlife during this tour includes spiders, frogs, toats, snakes, opposums and sometimes even sleeping mammals. The tour usually starts with some time next to the El Remanso pool or our new "frog pond" where different types of frogs and toats can be found. The most looked for is certainly the red-eye tree frog (Agalychnis callidryas), the most "photogenic of the frogs in the pond"! At the beginning of yesterday's nighthike, Rinaldo spotted a young mussarana snake. Unlike the adult snake, which is all black, the young mussarana has a beautiful red color. Mussaranas (Clelia clelia) are known to be a natural predator of the poisonous Fer-de-lance snake. It can be up to six feet in length. It actually hunts an assortment of snakes, many of them venomous. It seems to be immune to the toxins and is thus an important means of controlling viper populations. On the return from the creek, another surprise for our guests, a boa (Boa constrictor) curled around a a heliconia leaf next to the lobby, waiting for some prey to come nearby! So, come and join us in a discovery of the rainforest at night at the El Remanso Lodge!
