Common Potoo (<i><a href="//commons.wikimedia.org/wiki/Nyctibius_griseus" title="Nyctibius griseus">Nyctibius griseus</a></i>). We saw this nocturnal bird in Caroni Swamp, Trinidad.  It hunts at night but during the day it perches upright on a tree stump, and is very hard to see as it looks like part of the stump because it stays so completely still as it perches.
