What does a long-billed starthroat sound like?
The Long-billed Starthroat makes various short, high-pitched calls, including sharp "tseet" and "tsip" sounds. Its song is a weak, warbling trill, often mixed with sweet whistles. It also incorporates mimicry of other bird species in its vocal repertoire. Its key vocalization periods align with dawn and dusk, and it uses song flights at times, delivering its notes from mid-air.
Description
Long-billed starthroats are striking and mysterious birds. Despite their showy and extravagant plumage, they don't like to call attention to themselves in other respects. They predominantly stick to the woodland edge where they prefer to forage by themselves, and are not too vocal, either.
The long-billed starthroat can weigh between 5.5to7.1grams and be from11to12centimeters tall.
The long-billed starthroat typically lives for around seven years. This is comparable to its closest relatives within the hummingbird family. Like many hummingbirds, the survival rate is the lowest in the first year of life, but if they survive this critical period, they can live a relatively long life for a bird of their size.

How to recognise a long-billed starthroat?
General appearance
The long-billed starthroat is a medium-sized hummingbird with a length of 10-11 cm. It flaunts a primarily green body, with green-bronze upperparts and glittering green underparts. The bird sports a distinguishable white spot behind the eye and its bill is straight, lengthy and reddish-black.
Male vs female
Male long-billed starthroats can be identified by the distinctive pink or purple streak that extends down their throats, which isn't present in females. The male also possesses a deeply forked, black tail. Females, on the other hand, showcase a rounded tail with white tips on the outer feathers.
Juvenile
Similar to the female, the juvenile long-billed starthroat lacks the adult male’s brilliant throat streak. Juveniles also have buffy fringes to the feathers on the upperparts. As they age, the buffy tips wear off resulting in a greener appearance.
Breeding and nesting habits of the long-billed starthroat
Mating behaviors
Long-billed starthroats engage in aerial displays where males showcase their flying prowess to attract females. These displays involve rapid and agile movements with vocalizations that signal fitness and readiness to mate.
Nesting details
Nests are usually constructed in low shrubs or branches, hidden among foliage. The nests are small, cup-shaped structures made from grass, lichen, spider silk, and plant fibers, providing concealment and security in dense vegetation, including garden environments.
Eggs and chick-rearing
Females lay two white eggs, incubating them for about 16 days. After hatching, the chicks are cared for by the female alone, who feeds them a diet of nectar and insects. Chicks fledge approximately 20 days post-hatch, with continuous feeding by the mother until they are independent.
What does a long-billed starthroat like to eat?
Insects
Nectar
Spiders
Natural diet
The long-billed starthroat primarily feeds on nectar, which it extracts from a variety of flowering plants using its long bill and specialized tongue. It often visits flowers from plant families such as Rubiaceae, Fabaceae, and Malvaceae. The bird also consumes small insects and spiders, which provide essential proteins. These are typically caught in-flight or gleaned from foliage and flowers.
Bird feeders
At bird feeders, the long-billed starthroat is attracted to sugar-water solutions, similar to those offered to hummingbirds. It prefers feeders with large perches and multiple ports, allowing it to feed comfortably. Adding fruits like bananas or oranges to the feeding station can also attract these birds, as they occasionally supplement their diet with fruits.

Where can you find long-billed starthroats?
Primary habitat
The long-billed starthroat typically resides in tropical and subtropical woodlands, shrublands, and humid lowland forests.
Additional range
This hummingbird's range extends from Southern Mexico to Panama, but it can occasionally be found as far north as Texas and Arizona during migration.
Do they migrate?
The long-billed starthroat is a species of hummingbird found primarily in Central and South America. Unlike some hummingbird species that undertake long migrations, the long-billed starthroat is generally considered non-migratory. It is predominantly resident throughout its range, which extends from southern Mexico through Central America to northern and central South America, including countries like Colombia, Venezuela, and Brazil. However, some populations may exhibit local movements in response to changes in food availability or environmental conditions. These movements are typically altitudinal rather than long-distance migrations. The bird inhabits a variety of habitats, including tropical lowland forests, gardens, and secondary growth areas, which provide a consistent food supply throughout the year. During periods of scarcity or breeding, some starthroats might move to adjacent areas where nectar-producing flowers are more abundant. Despite these local shifts, there are no well-documented, large-scale migratory patterns for this species. Instead, they adapt to seasonal changes within their established range, taking advantage of the diverse ecosystems available throughout their geographic distribution.
What is the role of long-billed starthroats in nature and how to protect them?
Conservation status
The long-billed starthroat is currently listed as Least Concern, indicating it is relatively common and not at immediate risk of extinction. This hummingbird species faces localized threats mainly from habitat loss due to deforestation and land conversion for agriculture. Conservation efforts focus on preserving natural habitats and promoting sustainable land use. While not currently vulnerable or endangered, monitoring of population trends and habitat conditions is essential to ensure long-term stability. Key threats include habitat fragmentation and climate change, which could alter the environments this species depends on for feeding and breeding.
Ecological role of long-billed starthroats
Its role in the ecosystem
The Long-billed Starthroat (Heliomaster longirostris) is a hummingbird species found in Central and South American ecosystems. Ecologically, it plays a crucial role in pollination due to its feeding behavior. It sips nectar using its long bill and, through this process, pollen can get stuck on its bill and feathers, which is then transported to other flowers aiding in their pollination. This particularly helps in maintaining the biodiversity of the forests where they inhabit. Additionally, the Long-billed Starthroat, like other hummingbirds, is also known to feed on insects. This predatory behavior provides ecosystem-level benefits by controlling the population of certain pests, thereby helping stabilize the ecosystem. The excretory products of hummingbirds also contribute to soil nutrient cycling, which indirectly promotes plant growth. Overall, the Long-billed Starthroat contributes substantially to its ecosystem through pollination, pest control, and nutrient cycling.
