Agapornis nigrigenis
Species Authority: The species authority, or the name(s) of scientist(s) or person(s) who first described Agapornis nigrigenis is Sclater, 1906 (IUCN Red List). Country Distribution: Agapornis nigrigenis is found in the following countries:
Biome(s)/Ecosystem(s): IUCN lists the following as biomes for Agapornis nigrigenis: Terrestrial (IUCN Red List). Major Habitat(s): 1.5 Forest - Subtropical/Tropical Dry 11.1 Artificial/Terrestrial - Arable Land (IUCN Red List). Range: Agapornis nigrigenis occurs patchily in south-west Zambia between the Kafue river to the north and the Zambezi river to the south8, with an Extent of Occurrence of c.14,400 km, within which the core breeding areas cover c.2,500 km 2,4. It used to occur more widely2,4, although some isolated historical records may reflect feral populations4, as may unconfirmed records from the eastern Caprivi region of Namibia2,4. It has also been recorded from Botswana, and as possibly breeding in Zimbabwe. In 1994, the overall population density in presumed breeding habitat was c.2.2 birds/km (this does not reflect their clumped distribution10) and the total population was estimated to be 10,000 individuals4. Evidence from farmers and bird-trappers suggests that this is a considerably lower total than in the early 20th century4,7. (IUCN Red List). CONSERVATION STATUS Red List Category & Criteria: Agapornis nigrigenis is listed as VU C2a(ii) ver 3.1 (2001) (IUCN Red List). Year Assessed: Agapornis nigrigenis's status was assessed in 2006 (IUCN Red List). Assessor: Agapornis nigrigenis's Red List status was evaluated by BirdLife International (IUCN Red List). Red List Evaluator: The Red List Evaluator for Agapornis nigrigenis is listed by IUCN as Butchart, S. & Pilgrim, J. (BirdLife International Red List Authority) (IUCN Red List). Red List Rational / Justification : Agapornis nigrigenis is listed by IUCN for the following: This species is listed as Vulnerable since it has a small population which is undergoing a continuing decline owing to habitat loss and degradation, particularly gradual dessication of water bodies. (IUCN Red List). Red List History: Agapornis nigrigenis was listed on the IUCN Red List of Threatened Species in 1988 (IUCN Red List).
