The great potoo or grand potoo is the largest potoo species and is widely distributed in Central and South America.Much like owls, this species is nocturnal. It preys on large insects and small vertebrates, which it captures in sallies from high perches.
📌 Taxonomy
The great potoo was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Lineus's Systema Naturae. He placed it with all the nightjar like species in the genus Caprimulgus and coined the binomial name Caprimulgus grandis. The great potoo is now one of the seven potoos placed in the genus Nyctibius that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot. The genus name is from Ancient Greek nuktibios meaning "night-living", from "night" and "life". The species is monotypic: no subspecies are recognised.
📌 Distribution and habitat
They range from southern Mexico through northeastern Guatemala and through most of Central America down through South America as far as southeastern Brazil and Bolivia.
In general, the great potoo are distributed from humid to semi-humid forested habitats. While this species is widely spread out geographically, there is little to no variation in their appearance, such as size or plumage.
📌 Behavior
This nocturnal predator is usually seen perched high above the ground while foraging, hawking when prey is spotted. After the pounce, the potoo almost always returns to its previous perch. Normally, during the day, it perches upright on a tree stump and is overlooked because it resembles part of the stump; this is a camouflage, not just by coloration, but a camouflage by the setting. The Great Potoo can be located at night by the reflection of light from its eyes as it sits vertically on a post, roost, or angled tree trunk. Great potoos are shy and solitary creatures. However, they have begun to perch on man-made things such as plastic bottles. This proves how people continue to affect wildlife and natural habitats in the present day.
📌 Breeding
Breeding has been recorded as typically February to August, but depending on the portion of this bird's range breeding birds can be met with almost year-round. The nest is a slight depression on a thick tree branch, at least above ground, with a single white (slightly spotted) egg measuring about . Few details are known of the brooding behavior, but about a month elapses before the offspring is seen alone at the nest. A chick of a few days old weighed .
📌 Feeding
Their prey consists mostly of large flying insects, especially large beetles, katydids and Orthoptera (including crickets and grasshoppers). Bats and birds are taken occasionally as well. The great potoo takes advantage of the night and its natural camouflage by sitting on an exposed perch to wait until some prey flies by, at which point it darts out towards the prey and returns to the branch with it. Very often birds of this species will use the same hunting perch nightly.
📌 Conservation status
According to the International Union for Conservation of Nature (IUCN), due to its large range, the great potoo is seen as a species of least concern. Although it is normally described as "uncommon", it occurs frequently in areas of less disturbed forests and is often found to be rare along the edges of its range. Forest clearing is the only conservation threat known to this bird.
📌 Effects of humans
The local people in the rural area of Brazil sometimes use potoo as a minor food source, as they do not offer much meat and are hard to locate. In these areas, their feathers are believed to have powers to provide chastity, so they are hunted down for their body parts, which are used to perform ceremonies. It is also believed that parts of their body ward off seduction. Potoos fear most locals due to being hunted.
