The Long-tailed Potoo (Nyctibius aethereus) Read in Spanish

Appearance: The Long-tailed Potoo is named for its remarkably long tail, which distinguishes it from other Potoo species. It has intricately mottled plumage in shades of brown, black, and gray with streaks and patterns that aid in its camouflage. The bird's large eyes and wide mouth are adapted for its nocturnal lifestyle, allowing it to hunt insects under the cover of darkness.

Habitat: The Long-tailed Potoo inhabits tropical lowland forests, including rainforests and gallery forests. It prefers dense forest habitats with tall trees where it can roost during the day and hunt for insects at night. These birds rely on their excellent camouflage to blend in with tree bark or branches, making them challenging to spot even in their natural habitat.

Behavior: The Long-tailed Potoo is primarily nocturnal, spending the daylight hours perched motionless on branches to avoid detection. They are expert insect hunters, capturing prey on the wing using their wide mouths. These birds are known for their haunting vocalizations, including mournful wails and whistles, which play a crucial role in communication and territorial defense.

Breeding: The breeding habits of the Long-tailed Potoo involve courtship displays, vocalizations, and the selection of suitable nesting sites in tree branches or forks. Females typically lay one or two eggs in a well-camouflaged nest, where they are responsible for incubating the eggs and caring for the chicks.

Conservation Status: The Long-tailed Potoo is not considered globally threatened.

Distribution

The Long-tailed Potoo (Nyctibius aethereus)

Eastern Andes: The Long-tailed Potoo can be found in the Eastern Andes region, which extends through several departments, including Boyacá, Cundinamarca, Meta, and Tolima.
Within the Eastern Andes, the bird inhabits montane forests and cloud forests, utilizing the dense vegetation and tall trees for roosting and hunting.

Amazon Rainforest: The Long-tailed Potoo is also present in the Amazon region, particularly in the southern part of the country that borders Peru and Brazil. Within the Amazon Rainforest, the bird thrives in the lush tropical forests characterized by high biodiversity and dense canopy cover.

Orinoco River Basin: The Long-tailed Potoo's distribution extends into the Orinoco River Basin in eastern Colombia, covering areas in departments like Arauca, Casanare, and Vichada. Within this region, the bird occupies gallery forests, riverine habitats, and savannas where it can find suitable perches for camouflage and hunting.

Northern Colombia: Reports of Long-tailed Potoos have also been documented in northern Colombia, including regions near the Caribbean coast and Sierra Nevada de Santa Marta. The bird may occur in the foothills of the Sierra Nevada and adjacent lowland forests where suitable conditions for foraging and breeding are present.
