About the Black Inca
The Black Inca, scientifically named Coeligena prunellei, is a captivating hummingbird that belongs to the Trochilidae family, residing primarily in the cloud forests of Colombia. This striking bird is renowned for its glossy black feathers and the iridescent blue-green patch on its throat, which shimmers in sunlight. Despite its beauty, the Black Inca faces significant conservation challenges due to habitat loss and fragmentation. Its natural habitat, the subtropical and tropical moist montane forests, is often threatened by agricultural expansion and deforestation. The Black Inca plays a crucial ecological role as a pollinator, particularly in its native Andean regions. By feeding on nectar, it facilitates the pollination of various flowering plants, contributing to the health and diversity of these ecosystems. Its presence is an indicator of biodiversity and forest health, as it thrives in undisturbed habitats. During the breeding season, which aligns with the rainy months in the Andes, the Black Inca becomes particularly active, engaging in elaborate courtship displays. Outside of the breeding season, it displays more solitary behavior, focusing on foraging and maintaining territory. The bird’s ecological significance extends beyond its immediate habitat, as it supports the broader network of species dependent on the cloud forest ecosystem. Given its restricted range and specialized habitat requirements, the Black Inca is considered a vital species for conservation efforts in Colombia.
The Black Inca belongs to the family Trochilidae, within the order Apodiformes. These birds typically live average 4-6 years, with a max recorded of 8 years..
How to Identify a Black Inca
The Black Inca is a medium-sized hummingbird, measuring approximately 10-12 cm in length. Its most distinguishing feature is the velvety black plumage that covers most of its body, contrasting sharply with the vibrant, iridescent blue-green throat patch visible when reflecting light. This feature is particularly prominent in males, who display it during courtship rituals. Females, while similar in size and shape to males, typically have a slightly duller throat patch. Juveniles resemble females but often exhibit a more subdued coloration overall, including less vibrant throat patches. In flight, the Black Inca showcases a silhouette characterized by rapid wing beats and a straight, slightly downward curved bill adapted for nectar feeding. While perched, it maintains an upright posture, often seen gripping branches with its strong feet. The Black Inca can be confused with other species of Coeligena hummingbirds, but its unique combination of black plumage and blue throat patch sets it apart. Observing these features closely, especially in good lighting, helps accurately identify the species.

Black Inca Habitat and Range
Preferred Habitat
The Black Inca primarily inhabits the subtropical and tropical moist montane forests of Colombia, specifically within the Andean cloud forests. These environments provide the dense canopy cover and abundant flowering plants necessary for its survival. Elevation plays a crucial role in its habitat preference, with the bird typically found at altitudes ranging from 1,200 to 3,000 meters. These high-altitude forests offer a humid climate and a rich diversity of flora, crucial for the Black Inca’s nectar-based diet. Although primarily a forest dweller, the Black Inca occasionally ventures into forest edges and clearings, especially when searching for food. Seasonal shifts in habitat are generally minor, as the bird remains within its montane forest range throughout the year. In terms of urban presence, the Black Inca is seldom seen, as its dependence on specific forest types makes it less adaptable to urban environments compared to more generalist species.
Geographic Range
The Black Inca is an endemic species, found exclusively in Colombia. Its range is confined to the western and central Andes, where it occupies a relatively narrow band of suitable cloud forest habitat. Within this range, population density hotspots occur in areas with well-preserved forest cover, such as the Serranía de Yariguíes and the Cordillera Occidental. The Black Inca does not undertake long-distance migrations, remaining within its core range year-round. However, it may exhibit altitudinal movements in response to seasonal changes in flower availability, moving to slightly lower elevations during periods of scarce resources. This restricted range and specific habitat preference contribute to its vulnerability, as habitat loss in these regions directly impacts its population. Conservation areas and protected reserves play a crucial role in maintaining the natural habitats needed for the Black Inca’s survival.

What Does the Black Inca Eat?
The diet of the Black Inca primarily consists of nectar from a variety of flowering plants, which it accesses using its specialized bill. It favors flowers with tubular shapes, which complement its long bill and tongue, allowing efficient extraction of nectar. In addition to nectar, the Black Inca supplements its diet with small insects and arthropods, providing essential proteins and nutrients. This opportunistic insectivory is particularly important during the breeding season when energy demands increase. The bird employs a hover-feeding technique, meticulously maneuvering in front of flowers to access nectar. Seasonal diet variations occur as the availability of flowering plants changes, prompting the Black Inca to seek out different nectar sources throughout the year. Feeding activity peaks during early morning and late afternoon when flowers are most abundant with nectar.

Black Inca Behavior and Social Structure
The Black Inca exhibits a range of intriguing behaviors, influenced by its role as a territorial and solitary hummingbird. Males are particularly defensive of their feeding territories, often engaging in aggressive displays to ward off intruders. These displays include chasing, vocalizing, and showing off their iridescent throat patch. During the breeding season, males perform elaborate courtship displays to attract females, which involve aerial acrobatics and vocalizations. Despite their territorial nature, Black Incas may occasionally form loose associations around abundant food sources, where multiple individuals can feed without direct competition. Their daily activity patterns involve periods of intense feeding interspersed with rest, often taking shelter in the dense foliage of their forest home. In response to predators, the Black Inca relies on its agility and speed, often outmaneuvering threats with rapid flight. While generally solitary, these birds are keenly aware of their surroundings, constantly monitoring for both threats and feeding opportunities.
Black Inca Nesting and Reproduction
The nesting habits of the Black Inca reflect the meticulous nature of hummingbird breeding. Females take the primary role in nest construction, selecting sites in dense foliage or on horizontal branches, often near a reliable food source. The nest is cup-shaped, constructed using plant fibers, spider silk, and other natural materials, providing a secure and camouflaged environment for eggs. Typically, the clutch size consists of two white eggs, with the female responsible for incubating them over a period of approximately 15 to 17 days. After hatching, the altricial young are cared for solely by the female, who feeds them regurgitated food. The fledging period lasts about 20 to 25 days, during which the young develop the necessary strength and skills for independent flight. The Black Inca usually raises one brood per year, although favorable conditions may occasionally allow for a second.
Black Inca Sounds and Vocalizations
The Black Inca's vocalizations are characterized by a series of sharp, high-pitched calls. These calls, often described as 'tseet' or 'tsip', serve both as contact calls between mates and as territorial signals to ward off rivals. During courtship displays, males produce a more complex song, consisting of rapid trills and whistles that vary in pitch and intensity. This song, though not as melodious as that of some other birds, plays a crucial role in attracting females. Alarm calls are more abrupt and are used to alert other birds to the presence of predators. While not known for a dawn chorus, the Black Inca's vocal activity peaks during early morning, coinciding with periods of heightened feeding activity.
