These days we had an unexpected surprise. Suddenly, a Boa constrictor (Boa constrictor amarali, jibóia) fell off a tree just next to one of us. The snake was holding on a Chaco Chachalaca (Ortalis canicollisAracuã), which it had killed by constriction up in the tree. The bird was already 20 cm down the snake's throat.
The same way we heard the blunt noise of the snake hitting the ground, a fox also did and came to inspect and challenged the snake. At this point snakes are completely vulnerable because they've got their mouth full! Seeing no alternative, the snake had to regurgitate the bird and then hiss to the fox ...

The forked tongue is used to smell.

Just regurgitated the bird.

And sometimes there are snakes

During the wet and hot months of October through April, snakes are more commonly seen. One of the most fear causing animals is the tropical rattlesnake (Crotalus durissus terrificus, Cascavel). This pit viper advertises itself by a loud shaking of it´s rattle at the end of the tail (see and listen to a red rattlesnake here!).

Their diet consists of small rodents and birds. Although encounters like these are rare, one should be cautious when walking around in the wild. However, rattlesnakes rarely bite unless provoked or threatened; and if treated promptly, the bites are rarely fatal.
