Biology ( 英語 )

由Arkive提供
The shy Gabela akalat is thought to feed solely on insects, gleaning them from leaves and branches in the forest undergrowth. Almost nothing is known about the breeding biology of the Gabela akalat except birds in a breeding condition have been found in September. This bird often remains motionless for long periods (2).

Conservation ( 英語 )

由Arkive提供
For the duration of the protracted civil war, very little scientific research was undertaken in Angola. Since the war was formally ended in 2002, surveys to determine the Gabela akalat's population size and distribution could now be carried out (2). Ascertaining the call of this shy bird would be extremely useful in any future surveys that are undertaken; in 2004 a group of scientists first recorded a call emanating from the location of a Gabela akalat, but more work is needed to confirm its repertoire (4). The bird conservation organisation BirdLife International also recommends that the forest at Gabela should be designated as a protected area (2).

Description ( 英語 )

由Arkive提供
Akalats are small, rather short-tailed robins (3). This akalat, named after the town near which it was discovered, has drab brown plumage, with an indistinct brown breast band, and a contrasting whitish throat and pale belly (2) (3). It has long legs, an upright stance, and a robin-like walk (3). It is thought that the Gabela akalat calls with a soft, deep and mournful 'tseeo tseeo tseeo tseeo' (4).

Habitat ( 英語 )

由Arkive提供
The Gabela akalat inhabits the dense understorey of primary and secondary forest. It has also been observed in scrub at the edges of coffee plantations, but is thought to be dependent on more intact forest (2).

Threats ( 英語 )

由Arkive提供
Prior to 1974, large areas of forest in Angola were lost to the establishment of coffee plantations, but with the start of the civil war, many of the plantations around the Gabela district were abandoned and the forest understorey recovered significantly. With the cessation of hostilities in 2002, pressure on the forest will again increase as demand for agricultural land grows (4). A growth in subsistence agriculture now poses the greatest threat to the Gabela akalat and other forest-dwelling birds of the region (2) (4). In some areas, 20 to 70 percent of canopy trees and all the undergrowth in valley bottoms are being cleared to plant bananas and sweet potatoes. In other areas, up to 95 percent of the forest canopy is being removed to plant cassava and maize (2). In addition, the re-establishment of coffee plantations would also have serious impacts on the Gabela akalat, particularly if varieties that require shade (which thrive beneath the canopy of forests) were replaced by sun-tolerant varieties (which results in the destruction of the forest canopy) (4).

Gabela-akalat ( 荷蘭、佛萊明語 )

由wikipedia NL提供

Vogels

De gabela-akelat (Sheppardia gabela) is een zangvogel uit de familie Muscicapidae (vliegenvangers). Het is een bedreigde, endemische vogelsoort in Angola.

Kenmerken

De vogel is 13 cm lang. Het is een vliegenvangerachtige vogel die lijkt op de roodborst, maar dan zonder rode borst en nogal grauw en onopvallend gekleurd. Van boven is de vogel dofbruin en van onder lichtgrijs, met een lichtbruine band over de borst en een opvallend lichte keel die contrasteert met het lichtbruin op de borst. De vogel is schuw en daarom lastig waar te nemen.[1]

Verspreiding en leefgebied

Deze soort is endemisch in Angola. Het leefgebied bestaat uit de laatste resten primair en secundair natuurlijk bos in heuvelland boven de 1100 m, waar de vogel voorkomt in de ondergroei.[1]

Status

De gabela-akelat heeft een beperkt verspreidingsgebied en daardoor is de kans op uitsterven aanwezig. De grootte van de populatie werd in 2016 door BirdLife International geschat op 15 tot 30 duizend individuen en de populatie-aantallen nemen af door habitatverlies. Het leefgebied wordt aangetast door ontbossing waarbij natuurlijk bos wordt omgezet in gebied voor zelfvoorzieningslandbouw. Om deze redenen staat deze soort als bedreigd op de Rode Lijst van de IUCN.[1]
