The common potoo (Nyctibius griseus) can be found throughout Trinidad and Tobago in forested areas, including mangrove swamps like this one in the Rousillac Swamp. Cryptic plumage allows the bird to remain well camouflaged as it sleeps during the day on its favourite branch (you can see that the bird in the photo is actually watching as its eyes are not completely shut). As darkness falls, it becomes active, keeping watch for flying insects. Their call is a very haunting and mournful series which used to be wrongly attributed to the silky anteater!
