Nombre en español: Ermitaño Piquigrande

Nombre en inglés: Great-billed Hermit

Nombre científico: Phaethornis malaris

Familia: Trochilidae

El ermitaño piquigrande o ermitaño picogrande​ (Phaethornis malaris)​ es una especie de ave apodiforme de la familia Trochilidae que se vive en América del Sur. Se encuentra en Bolivia, Venezuela, Colombia, Ecuador, Perú, Guayanas y el norte y oeste de Brasil.

Hábitat

Vive en los sotobosque y los bordes del bosque húmedo tropical, preferentemente en tierra firme, hasta los 1000 m de altitud.​

Descripción

Mide en promedio 16,5 cm de longitud.​ Cabeza y dorso verde grisáceo metálico, pardo y con pintas negruzcas hacia la grupa; superciliar y bigteras blancas a amarillentas, con banda apizarrada o negruzca en torno a los ojos; pecho y vientre color ante; cola negra con puntas blancas. Pico arqueado de 42 mm de largo.​

Taxonomía

Resulta polémica la clasificación de las subespecies insolitus, moorei, ochraceiventris, bolivianus y margarettae, en primer lugar, hay discusión si se asignan a esta especie o al colibrí colilargo (Phaethornis superciliosus). Además algunos autores consideran al ermitaño de Margarita una especie separada como Phaethornis margarettae.

​Great-billed hermit

The great-billed hermit (Phaethornis malaris) is a species of hummingbird in the family Trochilidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Peru, Suriname, and Venezuela.

Taxonomy and systematics

The great-billed hermit’s taxonomy is confusing. What are now the long-billed hermit (P. longirostris) and long-tailed hermit (P. superciliosus) were considered conspecific and included many subspecies that are now assigned to the great-billed hermit. A satisfactory taxonomic treatment of the entire P. longirostris/P. superciliosus/P. malaris group is still lacking according to some Neotropical ornithologists.

These six subspecies of great-billed hermit are generally recognized:

• P. m. malaris Nordmann (1835)
• P. m. insolitus Zimmer (1950)
• P. m. moorei Lawrence (1858)
• P. m. ochraceiventris Hellmayr (1907)
• P. m. bolivianus Gould (1861)
• P. m. margarettae Ruschi (1972)

The subspecies P. m. margarettae is sometimes treated as a separate species, «Margaretta’s hermit» (P. margarettae), and P. m. ochraceiventris has also been considered for species rank. At least two other populations within the existing subspecies have been suggested as additional subspecies.

Description

The great-billed hermit is 13 to 17.5 cm (5.1 to 6.9 in) long. Males weigh 4.5 to 10 g (0.16 to 0.35 oz) and females 4 to 8 g (0.14 to 0.28 oz). The nominate subspecies is the largest. It has greenish-brown upperparts and brownish to grayish underparts. Its uppertail coverts have dark and light ochre bands and the central tail feathers are long with long white tips. It has a long decurved bill, with the female’s being shorter but more curved than the male’s. P. m. insolitus is smaller than the nominate but otherwise similar. P. m. moorei has paler, grayer, underparts than the nominate. P. m. bolivianus and P. m. margarettae are the smallest subspecies. The former has a dark brown throat and breast and an orange-ochre belly; P. m. margarettae is very similar to bolivianus but has paler underparts. P. m. ochraceiventris has a bright orange breast and belly.

Distribution and habitat

The subspecies of great-billed hermit are found thus:

• P. m. malaris, Suriname, French Guiana, and north central Brazil’s Amapá state
• P. m. insolitus, eastern Colombia, southern Venezuela, and the northwestern part of Brazil’s Amazonas state
• P. m. moorei, eastern and southern Colombia through eastern Ecuador into northeastern Peru as far as the Marañón River
• P. m. ochraceiventris, northeastern Peru south of the Marañón River east into western Brazil south of the Amazon River as far as the Madeira River
• P. m. bolivianus, southeastern Peru to central Bolivia and into western Brazil between the Madeira and Tapajós rivers
• P. m. margarettae, coastal eastern Brazil from Pernambuco south to Espírito Santo

The subspecies inhabit the understory of a variety of rainforest landscapes including terra firme, foothill, and higher elevation tropical forest; transitional forest; secondary forest; and bamboo thickets. P. m. ochraceiventris in addition is found in igapó forest. In most areas it is found below 600 m (2,000 ft) of elevation but occurs as high as 1,500 m (4,900 ft) in Colombia and 2,400 m (7,900 ft) in Bolivia.

Behavior

Feeding

The great-billed hermit is a «trap-line» feeder like other hermit hummingbirds, visiting a circuit of a variety of flowering plants for nectar. Examples include Heliconia and Pitcairnia. It also consumes small arthropods.

Breeding

The great-billed hermit’s breeding seasons vary across its range, for instance at least August to December in French Guiana, June to September in Bolivia, and June to November in Peru. Like most hermits, it builds a cone-shaped nest of plant fibers and spider silk suspended from the underside of a drooping leaf. The clutch size is two eggs.

Vocalization

The great-billed hermit’s song is generally «a continuous series of single, bisyllablic rising, falling ‘slee-up’ notes» that differs somewhat among the subspecies. It also makes «a sharp ‘skweep!'» call, usually in flight.

Status

The IUCN has assessed the great-billed hermit as being of Least Concern, though its population size is not known and is believed to be decreasing. However, «[subspecies] margarettae, limited to forest remnants in [eastern] Brazil, could be threatened by further habitat destruction.»
