The Middle American Rattlesnake is a large, venomous snake. It has a drab color pattern, consisting of dark diamond-shaped blotches on a light brown base coloration. The key differentiator with all other venomous species in Costa Rica is the rattle, which produces a loud, menacing sound when it is vibrated rapidly. Indeed this sound causes fear in most people, as it is associated with the killer nature of these animals. Rattlesnakes however use this sound more as a defensive strategy, trying to scare off potential predators. As long as one is careful not to approach this snake more than it allows, it should be safe to watch them on their habitat.
Another of the Motmot species, this one is pretty similar to the Lesson´s Motmot, but has rufous on the back and a great portion of the tail is bare shft, while other Motmot species have a tail that is bare only in the tip; its song is quite different as well. This is the National Bird of El Salvador and Nicaragua. In Costa Rica, it can be found in Guanacaste and the Central Pacific, and ocassionally in the western central valley. Like most other Motmots, they construct their nests as cavities in mud walls, hence their local name in El Salvador: “Barranquero”. A trio of these birds perched very close to the road towards Barra Honda National Park, Guanacaste.
