The Urutau bird, also known as the Potoo bird, stands out as one of the most exceptional and fascinating creatures on the planet.
Discover the intriguing characteristics of the Urutau bird, its distinct physical features, and the enigmatic aura it carries.
The Urutau bird, scientifically named Nyctibius grandis, is the sole member of the Nyctibius genus, and it inhabits the regions of Central and South America.
This bird possesses a remarkable connection to other avian species that share similar behaviors, such as nightjars and frogmouths. It belongs to the ancient lineage of owlet-nightjars, a group that emerged around 30 million years ago. Continue Reading to find more about this fascinating bird.
Physical Traits of the Urutau Bird
The Urutau showcases a solid black body, complemented by a lengthy tail and sturdy legs, seemingly designed for agile movement through treetops and branches. Its eyes, in contrast, are small and bead-like, optimized not for keen sight but for capturing even the faintest sources of light.
Visual Abilities of the Urutau Bird
Despite its seemingly limited sight, the Urutau bird’s eyes are effective even in low-light conditions. Given its nocturnal nature, this feature provides a distinct advantage for nocturnal hunting. Its unique tubular-shaped mouth aids in consuming a diverse array of insects, sustaining it throughout the night.
Habitat and Behavior of the Urutau Bird
The Urutau bird thrives in forested areas adjacent to water bodies, where it primarily feeds on smaller insects like moths, beetles, and flies. Additionally, its diet includes spiders, snails, and frogs. In urban settings, these birds often nest on man-made structures during the breeding season. On occasion, they might also seek shelter within tree hollows or rock crevices.
The Latin name of this remarkable creature, Nyctibius grandis Urutau, translates to “large Urutau nightjar,” underscoring its connection to the nightjar family.
Urutau Bird Behavior and Ecology
Urutau birds are diurnal creatures, meaning they are most active during the daytime. Throughout the night, they engage in flights between trees to search for food in the absence of light. When they detect a source of light, they descend slowly to the ground or onto branches, patiently waiting for prey like insects and worms moving on the surface.
Despite the presence of predators such as owls, eagles, and small mammals, Urutau birds breed consistently throughout the year. Their internal fertilization leads to the birth of live young, contributing to the success of the Urutau species. Nest construction involves utilizing sticks, twigs, vines, and leaves, with nests perched on branches.
Geographical Distribution and Dietary Habits
Urutau birds are distributed across South America and parts of Central America. Their presence can also be observed along the coasts of Argentina’s Atlantic Forest, where they nest on willow trees by rivers and wooded lakesides. They tend to favor habitats near water sources for hydration purposes.
In terms of diet, Urutau birds primarily consume insects like larvae, snails, spiders, and small frogs or mice found on the ground. In urban areas, they extend their diet to include small insects and occasionally lizards when available. Remarkably, Urutau birds can even fly above water surfaces to spot prey, relying on light reflections for detection.
Potoo Behavior and Ecology
Potoos are nocturnal avian inhabitants of Central and South America, recognized for their distinctive and cryptic behavior and ecological role. Key aspects of their behavior and ecology include:
Potoos are active during the night, using branches or perches as resting spots during the day. Their cryptic plumage aids in blending into the environment.
Potoos possess exceptional camouflage skills, allowing them to evade predators and perplex researchers. Their unique posture, with an upward-pointing beak and extended neck, mimics a broken branch or tree stump.
Potoos primarily feed on insects captured mid-flight. Their wide beak enables them to catch larger prey like moths and beetles.
Territorial Nature: These birds are generally solitary, defending their territories from other potoos. They communicate through vocalizations, often heard during nighttime in the forest.
Potoos lay eggs directly on bare branches or logs, forgoing traditional nest construction. The camouflaged eggs blend seamlessly with their surroundings. Both parents partake in incubation and caring for the young.
Threats and Conservation:
Habitat loss due to deforestation and logging, coupled with hunting for meat and feathers, poses threats to potoos. Conservation efforts aim to safeguard their habitats and mitigate hunting and poaching.

Survival and Reproduction
Urutau birds have limited predators, including owls, hawks, and snakes, with nocturnal hunting by these predators being the most common. Their primary threat, however, is humans seeking to collect eggs or capture them as pets, taking advantage of their nocturnal habits.
Elevated flights above lakes and ponds during the night expose Urutau birds to predation by eagles and large birds of prey. Parental care involves sitting on their young until they outgrow the nest, after which the parents venture out to establish territories within the forest.
Urutau birds do not construct traditional nests. Instead, they lay solitary eggs, with both parents contributing to incubation through body heat, much like penguins. Generally, only one egg is laid by the female Urutau.
Urusta: The Offspring of the Urutau Bird
Urusta, the young of the Urutau bird, comes into the world with closed eyes and a covering of light grey downy feathers across its body. As the young ones gradually open their eyes, they begin to develop adult feathers, transitioning into shades of brown and dark black-grey, signifying their maturity. During the breeding season, the male employs a simple call composed of two or three deep-toned notes to attract the female’s attention.
Other Fascinating Facts about the Urutau Bird
Numerous intriguing facets define this enigmatic bird, some of which border on the realm of the mythical. Here are a few highlights:
- Master of Camouflage This bird excels in camouflage, allowing it to blend seamlessly with its habitat’s trees. Its disruptive coloration helps it conceal from predators. When this strategy falters, the bird resorts to startling predators by opening its eyes and mouth before taking flight.
- Declining Population While Urutau birds are widespread, their population is decreasing due to habitat loss and deforestation. Despite being classified as “Least Concern” on the IUCN Red List, conservation efforts are necessary to preserve their habitats.
- Shy and Solitary Urutau birds are generally solitary and timid, often concealed in tall tree branches and avoiding communal living.
- Gender Ambiguity Distinguishing between male and female Urutau birds is a challenge for ornithologists due to their lack of visual distinctions, complicating behavioral observations.
- Eerie Vocalization The Urutau bird earns the moniker “ghost bird” due to its eerie, mournful, and spectral call. Some associate its call with death and misfortune, but this is rooted in superstition. Often referred to as the “poor-me-one,” its mournful whistle descends as “poor, me, all, alone.”
- Uncertain Lifespan The exact lifespan of the Urutau bird remains uncertain, but estimates place it at around 12 to 14 years, akin to related bird species.
- Predators and Prey Despite their unique appearance, Urutau birds face threats from predators such as owls, snakes, weasels, and various mammals. Eggs can also fall victim to theft.
- Harmless to Humans Despite evoking fear due to their appearance and calls, Urutau birds are harmless to creatures they do not perceive as prey, including humans.
- Nests and Nesting Urutau birds forgo nest construction, laying their eggs in suitable tree crevices. Incubation relies on body heat, reminiscent of penguins.
- Diverse Diet Contrary to superstition, Urutau birds do not consume spirits of the deceased. They primarily feed on insects, including moths, beetles, crickets, grasshoppers, and occasionally small birds or bats.
- Family Variety The Nyctibius genus comprises seven species, including Nyctibius bracteatus, Nyctibius grandis, Nyctibius aethereus, Nyctibius leucopterus, Nyctibius maculosus, Nyctibius griseus, and Nyctibius jamaicensis.
- Strangely Attractive Despite their enigmatic nature, Urutau birds contribute to the allure of the South American ecosystem.
- Eyes with a Twist Urutau birds can observe their surroundings even with closed upper eyelids, thanks to tiny folds forming slits, allowing them to remain vigilant while camouflaged.
- Monogamous Mates Urutau birds pair with one mate and breed during the rainy season in their habitat.
- Agile Flyers Though specific speeds are unknown, Urutau birds are recognized for their relatively swift flight.
