Have fun learning about a new endemic bird every day. We have colouring pages, puzzles, activities, and more. Download for free and enjoy learning about and celebrating nature!
Endemic Bird of the Day: Black-billed Streamertail
The Streamertail is a symbol of Jamaica’s national pride and our rich biodiversity. While the average Jamaican may not be able to easily differentiate the Black-billed Streamertail from its more widespread compatriot, the Red-billed Streamertail, this striking bird still captures the eyes and hearts of Jamaicans and visitors alike.
It is primarily found in eastern Jamaica, particularly in the parishes of Portland, St. Thomas, and parts of St. Mary. It is closely related to the Red-billed Streamertail known locally as “Doctor Bird”, but the two are distinct species, separated by both geography and subtle differences in appearance and behavior.
Measuring about 22-24 cm in body length including their tail streamers—long, prominent trailing tail feathers for which the male Black-billed Streamertail is most famous for! These tail streamers, which curve and flutter behind it as it flies, produce a distinctive humming sound. Males are an iridescent emerald green with a black bill, while females lack the extravagant tail and have a duller greenish-brown appearance with a white belly. The females of both species are very similar and not always distinguishable in the field. Identity is usually assumed based on location.
Black-billed Streamertails are nectarivores (primarily feed on nectar). They feed on the flowers of native plants like heliconias, wild bananas, and mistletoe; in doing so, they play a critical role in pollination, transferring pollen from flower to flower. They also snack on small insects and spiders to get the protein they need to stay strong. These agile birds are fiercely territorial, often defending feeding sites from rivals and other nectar-feeding species.
During breeding season, females build tiny cup-shaped nests out of plant fibers, moss, and cobwebs, usually attaching them to tree branches or vines. They lay one or two tiny eggs, which they incubate alone, while males focus on displaying and defending their territories.
Although currently classified as “Least Concern” by the IUCN, the Black-billed Streamertail faces threats from habitat loss due to deforestation, agricultural expansion, and infrastructure development. Conservation efforts, including habitat protection and responsible land management, are crucial to ensuring the survival of this extraordinary hummingbird.
A true gem of Jamaica’s forests, the Black-billed Streamertail is always a treat for nature lovers with its dazzling plumage and acrobatic flight, serving as a reminder of the island’s unique and fragile ecosystems. Learn more about this species, including its range, photos, and calls here. Great news!
