Banggai crow description
This medium-sized crow is entirely black with a light iris and relatively short tail. The slender-billed crow (Corvus enca) is very similar to the Banggai crow, but can be distinguished by its larger overall size, bigger bill and proportionately longer tail (2).
- Length: 39 cm (2)
Banggai crow biology
No information exists on the social, reproductive or feeding behaviour of the Banggai crow (4).Top
Banggai crow range
Visits to the Banggai islands in 1981, 1991 and 1996 yielded no definite records of this species, but observations of black crows on Banggai Island in 1981, and a small crow seen at the western end of Peleng Island (within Banggai archipelago) in 1991 gave hope that the species still occurred (4). This hope was fulfilled when, in 2007, further surveys of Peleng Island successfully located two specimens of Banggai crow (5).Top
Banggai crow habitat
The Banggai crow occupies montane forest (5).Top
Banggai crow status
The Banggai crow is classified as Critically Endangered (CR) on the IUCN Red List (1).Top
Banggai crow threats
Based on the small number of records for this species, and the rapid rates of habitat loss within its range, the Banggai crow is likely to have only a very small population (2). Unfortunately, it remains hunted by local residents of Peleng Island (5).
In addition, extensive deforestation threatens to claim the last remaining areas of this species’ habitat (2) (3) (4). The Banggai crow may also be affected by competition with the slender-billed crow (C. enca) (3).Top
Banggai crow conservation
Following its rediscovery, conservation efforts are being undertaken to protect the Banggai crow and its forest habitat, promoting sustainable agriculture, and possibly eco-tourism, as well as educating local people about the bird’s plight (2) (5).
Along with these efforts, further surveys and the establishment of a protected area are necessary to ensure that the Banggai crow is not lost again (2).Top
