Many of you will wonder what is a Potoo bird? The Potoo bird or Great Potoo also called Common Potoo is not confined to a single species but is any of seven species of birds in the family Nyctibiidae genus Nyctibius. They are also called "Poor-me-ones" because of their wailing haunting calls. They are part of the local folklore. There is a tale that the sound is that of a lost child calling for the mother. There are many superstitions like disaster happening to those who hear it attached to the call by humans. The call of the Potoo bird resembles the sound of wails, moans, and groans among humans. The call of the Potoo bird gives creepiness in the stillness of night emitting through the dark forest. They are heard rather than seen. These birds are related to frogmouths and nightjars.
The birds exist in tropical Central and South America. These birds are spotted in Mexico, Guatemala, and further south as Brazil. The habitat is dense lowland forest, woodlands, and meadows. There is geographical variation in size and plumage.
The seven species of Potoo birds have similar general features as well as behaviors but differ in inconspicuous and conspicuous ways. The appearance is not the feature that makes the species stand apart from each other. The color variation is maybe a shade lighter with white and grey feathers dominating above darker ones. This is not applicable to Common Potoos birds. The breeds are:
- Great Potoo, the biggest breed among the species.
- Rufous Potoo, a tiny, brown-coloured bird.
- White-winged Potoo, a Potoo acknowledged for its white wings.
- Long-tailed Potoo has extra-long tail feathers.
- Common Potoo, the most assorted and well-populated Potoo, it has two sub-species.
- Andean Potoo, a strange bird that resides in the mountains.
- Northern Potoo, a distinctive variety of Potoo that lives further north than others. It has two sub-species and several subspecies under it. In totality, it is five species.
Great Potoo among all the species is the largest and palest in color and has whitish plumage.

This is the main reason why ornithologists find it difficult to collect data on these birds. The different Potoo species look alike, hunt in a similar way, and habitat is the same. It is impossible to demarcate them and bring out the difference.
Potoo bird is 8-20 inches in length. The head is large and rounded. Bill is broad and a little hooked at the end. Potoo bird has the bug—yellow eyes along with jutting out pupils and broad mouth. The wings and tail are long. The feather of the Potoo bird is complicated styled grey, black, and brown merging with the tree bark. The upper eyelids of the Potoo bird have many tiny folds which create slits. They can see with their eyes closed.

Potoo birds perch vertically on dead branches as they sleep, and it is where they roost. They remain completely still for long periods. It is mostly 10 to 12 m above the ground. Dusk is their waking time. At this time, it lowers itself to a height of 1.5 to 2 m above the ground. They can spot their prey in the dark. The prey is caught by fast short and silent flights. After capturing the prey, it returns to the same branch. In the eventuality of danger, the bird freezes and it becomes even more difficult to notice it.
The nest-making habit is restrained. Potoo bird is very sedentary in the habit and they are seen trying to stowaway on ships. The flight is done through deep wing beats. Long wings and tails permit them high maneuverability when in flight.

They reproduce once a year. It is difficult to differentiate males from females as they look similar. A branch or stub is selected which has enough depression or crevice to lay a single egg. The color of the egg is chalky white conspicuous with grey and white color. Both parents incubate the egg for 30-35 days. The baby bird is tiny and covered in fuzz.
