The Marvelous Spatuletail (*Loddigesia mirabilis*) is a tiny, iridescent hummingbird endemic to a small region of the Peruvian Andes, renowned for one of the most extraordinary adornments in the bird world: the male sports only four tail feathers, two of which are elongated, wire-like shafts ending in large, violet-blue, flag-like spatules that cross behind its body and can be twirled independently in dazzling courtship displays. With a shimmering emerald-green back, snow-white belly, a brilliant blue crest, and a slender, black-tipped bill, this diminutive bird—barely larger than a human thumb—performs an intricate dance in which it hovers and swings its spatules in figure-eight patterns to impress females. Despite its breathtaking beauty, the species is critically endangered, threatened by habitat loss, and remains a cherished icon of avian marvel and conservation urgency.

Faits amusants

During mating displays, the male Marvelous Spatuletail performs a mesmerizing dance, swinging his two elongated outer tail feathers—each ending in a iridescent blue, spatula-shaped disc—independently like a pair of ballet fans, sometimes even crossing them above his head. These feathers can be rotated and moved in opposite directions, a unique adaptation not seen in any other hummingbird. Females lack the striking tail ornaments and are far more drab, relying on camouflage to avoid predators while nesting. The bird’s tiny size, about 4 to 5 inches long (with the tail accounting for half that length), and its extremely limited habitat—only found in a small area of the Rio Utcubamba valley in northern Peru—make it a rare, elusive gem.

Habitats et répartition

The Marvelous Spatuletail is endemic to a very small area in northern Peru, restricted to the upper Río Utcubamba valley in the Amazonas region. Its entire geographic range spans less than a few hundred square kilometers, occurring only at elevations between approximately 2,000 and 3,000 meters. This hummingbird inhabits humid montane cloud forests, particularly along forest edges, near streams, and in areas of secondary growth and forest clearings where specific nectar-rich flowering plants are abundant. The dense understory and moss-laden branches of these environments provide essential perches for its distinctive courtship displays and foraging.

Comportements & Reproduction

The Marvelous Spatuletail hummingbird exhibits a highly specialized courtship ritual where males perform intricate aerial displays, hovering in front of females while rapidly waving their two elongated, spatula-tipped tail feathers in a figure-eight motion, creating a loud buzzing sound. Females select mates based on the quality and synchronization of this dance, which is a key determinant of reproductive success. Social structure is solitary and territorial; males aggressively defend feeding territories, while females are also solitary except when nesting. A unique reproductive strategy involves complete male absence from parental care: females alone build cup-shaped nests from plant fibers and spider webs, typically placed on branches overhanging water, and incubate two eggs for about 16 days. The species exhibits a skewed sex ratio due to high male mortality from intense competition, forcing females to be highly selective.

Alimentation

The Marvelous Spatuletail (Loddigesia mirabilis) feeds primarily on nectar from a variety of tubular flowers, especially those of the genera *Fuchsia*, *Salvia*, and *Centropogon*, which it accesses while hovering in place using its long, slender bill and rapid wing beats. Interestingly, despite its elaborate tail feathers—two long, wire-like outer feathers tipped with violet discs—these do not hinder its ability to forage; the male’s spatules are held out of the way during feeding. Like all hummingbirds, it supplements its diet with small insects and spiders, which provide essential proteins and fats, catching them in midair or gleaning them from foliage. Its specialized bill is well-adapted to the curved corollas of its preferred flowers, and it may play a role in pollinating these plants as it moves from bloom to bloom in its small, remote range in northern Peru.

Couleurs

The male Marvelous Spatuletail has a brilliant iridescent green back and crown, a vivid blue throat, a white belly, and a black line through the eye; its most distinctive feature is the pair of long, slender outer tail feathers ending in large violet-blue spatules. Females are duller, with green upperparts and whitish underparts, lacking the elongated tail. No specific camouflage adaptations occur; the male’s striking colors and unique tail ornaments are for display rather than concealment.
