Categorías: Hipotéticas

El trepatroncos del Inambari​ (Lepidocolaptes fatimalimae), es una especie de ave paseriforme de la familia Furnariidae, subfamilia Dendrocolaptinae, perteneciente al numeroso género Lepidocolaptes. Es nativa de la Amazonia occidental en América del Sur.

Distribución y hábitat

Se distribuye en las selvas húmedas de la Amazonia occidental, en Brasil al sur del río Amazonas, y al oeste del río Madeira (Acre, sur de Amazonas) al oeste hacia la base de los Andes en el norte y centro de Bolivia (al este hasta Santa Cruz), este de Perú (San Martín y Loreto al sur hasta Cuzco y Madre de Dios).​

Sistemática

Descripción original

La nueva especie L. fatimalimae fue descubierta y descrita por los ornitólogos Elinete Batista Rodrigues, Alexandre Aleixo, Andrew Whittacker y Luciano Nicolas Naka en 2013, su localidad tipo es: «municipalidad de Guajará, 07°23’30.0” S, 72°45’32.53” W, Amazonas, Brasil». El holotipo se encuentra depositado en el Museu Paraense Emílio Goeldi sobre el número MPEG 74451.​

Etimología

El nombre genérico masculino «Lepidocolaptes» se compone de las palabras del griego «λεπις lepis, λεπιδος lepidos»: escama, floco, y «κολαπτης kolaptēs»: picador; significando «picador con escamas»;⁶​ y el nombre de la especie «fatimalimae», conmemora a la zoóloga y conservacionista brasileña Maria de Fátima C. Lima.​

Taxonomía

Es monotípica. De acuerdo a estudios de filogenia molecular con base en datos de ADN mitocondrial se demostró la existencia de cinco grupos recíprocamente monofiléticos en el complejo L. albolineatus, cada uno correspondiendo a taxones ya nombrados, excepto uno incluyendo aves al sur de los ríos Amazonas/Solimões y oeste del Madeira a quien se describió como la nueva especie Lepidocolaptes fatimalimae (Rodrigues et al. 2013). La distancia genética incorrecta, par a par, entre estos clados variaba desde 3.4% (entre duidae, fatimalimae, fuscicapillus, y layardi) a 5.8% (entre layardi y albolineatus). Vocalmente, estos cinco clados/taxones moleculares también probaron ser muy distintos, reforzando el argumento a su tratamiento como especies independientes (Rodrigues et al 2013).²​ La Propuesta N° 620 al Comité de Clasificación de Sudamérica (SACC) aprobada en diciembre de 2013, reconoció la nueva especie L. fatimalimae y elevó al rango de especies plenas a las anteriormente subespecies de albolineatus Lepidocolaptes duidae, Lepidocolaptes fuscicapillus y L. layardi (este último posteriormente considerado una subespecie de L. fuscicapillus). La nueva especie ya ha sido listada por el Congreso Ornitológico Internacional (IOC),​ por Clements Checklist, por el Comité Brasileño de Registros Ornitológicos (CBRO) y por el propio SACC.

​Inambari woodcreeper

The Inambari woodcreeper (Lepidocolaptes fatimalimae) is a species of bird in the subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, and Peru.

Taxonomy and systematics

The Inambari woodcreeper was described in 2013 as part of the reevaluation of Lepidocolaptes albolineatus, which was then called the lineated woodcreeper. Starting in the early 2010s, all but the lineated’s nominate subspecies were split from it, eventually resulting in recognition of the Inambari woodcreeper (which had not been known as a subspecies), the Duida woodcreeper (L. duidae), the dusky-capped woodcreeper (L. fuscicapillus), and a monotypic L. albolineatus which was renamed the Guianan woodcreeper. The Inambari woodcreeper’s specific epithet honors Fátima Lima, manager of bird collections at the Museu Paraense Emílio Goeldi. The Inambari woodcreeper is monotypic.

Description

The Inambari woodcreeper is 17 to 19 cm (6.7 to 7.5 in) long and weighs about 31 to 35 g (1.1 to 1.2 oz). It is a smallish, slim, woodcreeper with a slim decurved bill. The sexes have the same plumage. Adults’ face, crown, and nape are dark russet-brown with few or no spots on the crown. Their back and wing coverts are dark russet-brown, and their rump, wings, and tail rufous-chestnut with dusky tips on the primaries. Their throat is plain buffy. Their breast and belly are grayish brown to olive-brown with bold, brownish-edged, buff to creamy white streaks. Juveniles have darker upperparts than adults, a grayer crown with some spots, and whiter, somewhat reduced, streaks on the underparts.

Distribution and habitat

The Inambari woodcreeper is found in western Amazon Basin of eastern Peru, northern and central Bolivia, and western Brazil south of the Amazon River as far east as the Madeira River. It mostly inhabits terra firme and floodplain forest. It occurs less often in swamp forest and flooded várzea forest, and in shade coffee plantations in Peru. It favors the interior and edges of tall primary forest and mature secondary forest and is found only rarely in younger secondary forest. It elevation it seldom exceeds 1,000 m (3,300 ft) though it has reached 2,225 m (7,300 ft) in the Peruvian Andes.

Behavior

Movement

The Inambari woodcreeper is believed to be a year-round resident throughout its range.

Feeding

The Inambari woodcreeper’s diet is primarily arthropods. It usually forages singly or in pairs, and often joins mixed-species feeding flocks. It hitches along branches, often on their underside, mostly in the forest’s sub-canopy and canopy, occasionally in the middle levels, and rarely if ever in the understory. It takes most of its prey from bark, by picking, probing, and prying off flakes. It also sometimes probes vegetation like epiphytes but only infrequently sallies after airborne prey.

Breeding

Little is known about the Inambari woodcreeper’s breeding biology. Its breeding season seems to include late July to early August. It nests in cavities in trees. One nest contained two eggs.

Vocalization

The Inambari woodcreeper’s song differs from those of its former conspecifics; their songs were among the strongest evidence for their separation. Its song is «a soft trill comprising 16–37 notes (typically 26–33), like that of a becard (Pachyramphus) that trails off at end».

Status

The IUCN has assessed the Inambari woodcreeper as being of Least Concern. It has a large range, and though its population size is not known it is believed to be stable. No immediate threats have been identified. Because it is primarily a canopy specialist it is not well known; it is thought to be uncommon to fairly common throughout its range. It is «[b]elieved to be dependent on forest, thus likely to be highly sensitive to habitat modification».
