Le mangemort à gorge noire est une espèce de colibri coloré que l'on trouve dans les forêts de Colombie. Il a une gorge noire, un corps vert et un long bec recourbé. Il plane près des fleurs et se nourrit de nectar à l'aide de sa longue langue. Il est connu pour son vol énergique et son comportement territorial. Largement répandu mais peu commun, c'est un colibri assez grand et sombre avec un bec légèrement courbé. Le mâle est principalement vert avec du noir s'étendant jusqu'à la gorge et au ventre. La femelle a les parties inférieures blanches avec une ligne sombre au centre. Chez les deux sexes, la queue est violacée. Extrêmement similaire à la mangouste à poitrine verte, mais les aires de répartition se chevauchent très peu. On le trouve dans des habitats ouverts, notamment en lisière de forêt, dans les bois ouverts et dans les forêts arbustives de seconde zone.
Habitats et répartition
The Black-throated Mango inhabits a variety of environments including forest edges, open woodlands, gardens, and plantations. It is often found near flowering plants and can adapt to both lowland and montane regions up to 1,500 meters above sea level. This hummingbird prefers areas with abundant nectar sources, which provide necessary energy for its active lifestyle. Geographically, the Black-throated Mango is distributed across a wide range in tropical and subtropical regions of Central and South America, including countries like Panama, Colombia, Venezuela, and Ecuador. Its range extends as far south as northern Argentina and Brazil, and it is also present on some Caribbean islands. This broad distribution indicates its adaptability to different climates and habitats within the neotropical zone.
Comportements et reproduction
The Black-throated Mango exhibits intriguing social and reproductive behaviors that emphasize territoriality and solitary nest-building by females. Males are known to establish and vigorously defend their territories, often engaging in aggressive aerial displays to ward off rivals and attract females. Unlike many hummingbirds that display polygyny, Black-throated Mango males do not form lasting pair bonds with females and primarily focus on mating opportunities within their territory. Females undertake the responsibility of nest construction and rearing the young alone. They typically build their nests on tree branches, using plant fibers and spider silk to create a small cup-like structure. After a brief courtship and mating period, the female lays two tiny eggs, which she incubates for about 15-18 days. Upon hatching, the chicks remain in the nest for several weeks, during which the mother tirelessly feeds them with regurgitated nectar and insects until they are ready to fledge and become independent.

Statut de conservation et efforts
The conservation status of the Black-throated Mango (Anthracothorax nigricollis) is currently listed as Least Concern by the IUCN. Population trends are considered stable, with this hummingbird species widely distributed across northern and central South America through to southern Central America. Primary threats include habitat loss due to deforestation and land-use changes, although the species demonstrates resilience by adapting to secondary forests and human-modified landscapes. Conservation efforts for the Black-throated Mango focus on habitat protection and maintaining the ecological integrity of regions where it commonly resides. Environmental organizations work towards preserving large tracts of tropical and subtropical forests, and some regions implement reforestation projects to restore degraded areas. Public education and community engagement initiatives are also pivotal, striving to promote co-existence with hummingbird species and discouraging practices that lead to habitat destruction.
