A more stringent application of the assessment criteria of the formal Bird List of Namibia suggests that these 11 species are better conserved in category D until unequivocal evidence of their occurrence in Namibia is obtained. About 24% of Namibia's avifauna comprises widespread cosmopolitan species from two or more biogeographical regions of the world. Most of the Namibian and South African endemic and near-endemic birds on the Namibia Bird List were described from specimens originally collected in South Africa (70%), followed by Namibia (23%), Angola (6%) and Botswana (1%).

A brief bibliography of the most prolific authors on the bird species and subspecies of Namibia is given in Table 10. At the time of his death he was one of the most acclaimed scientists in Europe. The names of the type specimens of species and subspecies collected in Namibia often describe a characteristic of the bird, e.g.

Many of the type species and subspecies collected in Namibia are named after people and places. Various taxonomic notes on African birds LXV: On the so-called Mountain Pipit of the Afrotropics.

Category C - species introduced, human-assisted transportees or escapees from captivity and whose breeding populations (if any) are thought not to be self sustaining

Category C - Introduced species, transported by humans or escapees from captivity and whose breeding populations (if any) are not expected to be self-sustaining. The common myna in southern Africa usually spread by slowly expanding its range, from farm to farm, town and village to the next town or village without jumping more than 1000 km. So if they were present in south-west Namibia, it is likely that they were brought in and escaped or were released.

The house crow and common myna are potentially highly invasive and any specimens found in Namibia should be aggressively pursued and destroyed. Despite our opposition to caging birds, these species are unlikely to establish self-sustaining wild populations.

Category D - species reported to occur in Namibia but for which there is as yet no unequivocal evidence

Western Crested Heron Egretta gularis One record - Zambezi River, Zambezi East Region near Kalizo lodge June 2006 - unsubstantiated. ACCIPITRIFORMES: Accipitridae (Kites, vultures, buzzards, old world vultures, eagles, vultures, sparrows, lynxes) Rüppell's vulture Gyps rueppelli One unconfirmed record near Otjiwarong. Little Ringed Plover Charadrius dubius One unsubstantiated record from Fischer's Pan, Namutoni, Etosha National Park, August 1974.

Spotted Redstart Tringa erythropus Two unconfirmed records: Chobe River, November 1987 and Nkasa Rupara National Park at Linyanti Swamp, August 2002. A recent assessment suggests that these are hybrid Lesser Crested Terns native to western Europe (Cabot & Nisbet 2013). A recent assessment suggests that these are hybrid elegant-sandwich terns native to western Europe (Cabot & Nisbet 2013).

White-throated Raven Corvus albicollis Rare visitor to the Orange River Valley, no confirmed records in Namibia. Karoo Lark Calendulauda albescens Recorded along the South African north-west coast to Port Nolloth on the Orange River - not yet recorded on the north side of the river in Namibia. Red-faced Crombec Sylvietta whytii Records from Shamvura, Kavango East probably attributed to Long-billed Crombec, subsp S.

Fastidious Cisticola Cisticola natalensis Recorded in Botswana and Zimbabwe immediately adjacent to the eastern Zambezi region - but no confirmed records yet in Namibia. Fiscal flycatcher Sigelus mutes old records (early 1960s) from Sandwich Harbor & Kuiseb River unconfirmed - probably erroneous. A specimen collected by Eriksson (in Vänersborg Museum, Sweden) has no locality – probably collected in Angola.

Striped-headed seedeater Crithagra gularis Said to occur in extreme northeastern Namibia, but no confirmed records. Black-eared Seedeater Crithagra mennelli Said to occur in extreme northeastern Namibia, but no confirmed records. Endemic and near-endemic birds of Namibia (highlighted) and southern Africa and approximate percentage of the global population of each species occurring in Namibia.
