Leptocoma aspasia
The Black Sunbird, *Leptocoma aspasia*, is a small, vibrant passerine known for its striking plumage and acrobatic flight, often compared to hummingbirds due to convergent evolution. Males typically measure around 11-12 cm in length and weigh 6-9 grams, showcasing a brilliant metallic purplish-black body, often with iridescent green or blue flashes on the crown and throat, particularly under specific lighting. A distinctive red pectoral tuft, usually hidden, can be flared during displays. Fem...
This species thrives in a variety of tropical and subtropical lowland habitats, including evergreen forests, forest edges, secondary growth, plantations, gardens, and coastal mangroves, typically found from sea level up to moderate elevations of around 1,000 meters.
Primarily nectarivorous, the Black Sunbird feeds extensively on nectar from a wide array of flowering plants, often hovering or perching to probe blossoms with its long, curved bill. It supplements its diet with small insects and spiders, which are crucial for protein, especially during breeding,...
Black Sunbirds are highly active and diurnal, spending their days foraging energetically and often roosting communally in dense foliage at night. They are fiercely territorial, especially around prime flowering plants, and males will engage in aggressive aerial chases to defend their feeding patc...
The Black Sunbird is widely distributed across the Indo-Malayan and Wallacean bioregions of Southeast Asia and Melanesia, primarily as a non-migratory resident. Its extensive breeding range covers numerous islands, including much of the Philippines archipelago, Borneo, Sulawesi, the Moluccas (inc...
Least Concern
- The Black Sunbird's dazzling iridescent plumage is structural, meaning the colors are produced by the microscopic structure of the feathers, not pigments, causing them to shift with light angles. - Despite their resemblance and ecological niche, sunbirds are not related to New World hummingbird...
