Taxonomy

The Swallow-tailed Hummingbird belongs to the suborder Trochili and is classified under the species Eupetomena macroura. The type specimen, Trochilus macrourus, was first described by Gmelin in 1788. Initially, Jamaica was designated as the type locality; however, it was later corrected to Cayenne by Hellmayr. The subspecies macroura is the most recognized and widely studied.

Physical Characteristics

Eupetomena macroura is known for its striking appearance. The male typically exhibits iridescent green feathers on its back, with a distinctive long, forked tail that can reach impressive lengths. The tail feathers are often a mix of blue and green, creating a beautiful contrast. Females are generally less vibrant, featuring more subdued colors, but they still possess a certain charm with their elegant form.

Habitat

The Swallow-tailed Hummingbird thrives in a variety of habitats, primarily found in the Guianas and Brazil, extending south to the Amazon and its islands. This species prefers open areas, such as gardens, savannas, and forest edges, where it can easily access flowering plants. Its range also includes the interior of Brazil, reaching as far south as São Paulo and Mato Grosso, and into Paraguay.

Diet

Eupetomena macroura primarily feeds on nectar from a variety of flowering plants. Its long, specialized bill allows it to reach deep into flowers, making it an efficient pollinator. In addition to nectar, this hummingbird also consumes small insects and spiders, which provide essential proteins for its diet. The bird's foraging behavior is crucial for the ecosystem, as it aids in the pollination of many plant species.

Behavior

Eupetomena macroura is known for its acrobatic flight and territorial behavior. Males are particularly aggressive during the breeding season, often engaging in aerial displays to attract females and defend their feeding territories. Their flight patterns include rapid wing beats and sharp turns, showcasing their agility. These birds are also known to be highly vocal, producing a variety of chirps and whistles.

Reproduction

The breeding season for Eupetomena macroura typically occurs during the warmer months when flowers are abundant. Males perform elaborate courtship displays to attract females, which may include aerial dives and vocalizations. After mating, the female builds a small cup-shaped nest, usually located in a sheltered area, where she lays two eggs. The incubation period lasts about two weeks, and the female is solely responsible for caring for the young.

Conservation Status

Currently, Eupetomena macroura is not considered endangered, and its population is stable. However, habitat loss due to deforestation and agricultural expansion poses a potential threat to its future. Conservation efforts focused on preserving natural habitats and promoting sustainable land use practices are essential to ensure the continued survival of this beautiful species.

In summary, the Swallow-tailed Hummingbird, Eupetomena macroura, is a remarkable bird that plays a vital role in its ecosystem.
