Distribution of Loddigesia mirabilis in Peru

The marvelous spatuletail (Loddigesia mirabilis) is an

endemic to northern Peru.[3][4][1]

Taxonomy and systematics

The marvelous spatuletail is currently (early 2022) treated by worldwide taxonomic systems as the only member of its genus.

specific epithet because the spatuletail's mirabilis has priority.[7]

Description

Illustration of three males by John Gould

The male marvelous spatuletail is 15 to 17 cm (5.9 to 6.7 in) long including its 11 to 13 cm (4.3 to 5.1 in) tail. Females are 9 to 10 cm (3.5 to 3.9 in) long with a 5 to 7 cm (2.0 to 2.8 in) tail. The male's signature feature is its two outer tail feathers with bare shafts that cross each other and end in large purplish black racquets or "spatules". The remaining tail feathers are very short and are supported by two long undertail coverts. The female's outer tail feathers are also long, but shorter than the male's, and do not have the racquets.[8]

Both sexes have a slightly decurved black bill and a white spot behind the eye. Males have mostly green upperparts with a blue crest and a brownish hindneck. Their gorget is glossy blue-green and the rest of the underparts are white with a black line down the center. Females are also green above but do not have a crest or gorget. Their underparts are white without the male's black central line.[8]

Distribution and habitat

The marvelous spatuletail is found only in a small area in the

Alnus). In elevation it ranges between 2,100 and 2,900 m (6,900 and 9,500 ft) though there are unconfirmed reports both higher and lower.[1][8]

Behavior

Movement

The marvelous spatuletail is a year-round resident of its range.[8]

Feeding

The marvelous spatuletail forages by trap-lining, visiting a circuit of flowering plants where it perches to feed. It is most often seen feeding at a red-flowered lily (Bomarea formosissima) but has been observed feeding in at least five other species of flowering plants. It is dominated by other hummingbird species that share its range.[8]

Breeding

Little is known about the marvelous spatuletail's breeding phenology. Its breeding season appears to be between December and February but may extend from October to May. Males gather at leks and perform an aerial display.[1][8][9]

Vocalization

The male marvelous spatuletail gives "a repeated high-pitched buzzy metallic note...'tzzz...tzzz...'" during its aerial display. Its calls include "an upslurred high-pitched sweet note 'tswee'" and "a more strident 'tsik'".[8]

Status

The

IUCN originally assessed the marvelous spatuletail as Threatened, then in 1994 rated it as Vulnerable and since 2000 as Endangered. It is known from only two general areas and its population is thought to be smaller than 1000 mature individuals. Deforestation is rampant in its range though the species' preference for edge and scrubby habitats may somewhat ameliorate its effects. Males are hunted for traditional medicine, as their hearts are believed to be an aphrodisiac.[1]

In 2005, American Bird Conservancy provided Peruvian conservation partner ECOAN with support to sign a conservation easement with the Pomacochas Community to protect and manage about 100 acres (0.40 km2) of significant habitat for the marvelous spatuletail. Over 30,000 saplings of native trees and bushes have been planted there. This conservation easement is the first of its kind in Peru.[10][11]

In popular media

The marvelous spatuletail has been featured on the PBS TV series

Nature and two BBC TV series, Natural World and Life.[12][13]
