Larks (Alaudidae)
Barlow's Lark (Calendulauda barlowi)
French: Alouette de Barlow German: Barlowlerche Spanish: Alondra de Barlow
Taxonomy:
Pseudammomanes barlowi Roberts, 1937, 8 miles [c. 13 km] west of Aus, Namibia.
Forms a superspecies with C. burra, C. albescens and C. erythrochlamys; sister-species to last of those, with no known range overlap between the two. Recently split from C. albescens on grounds of genetic, morphological and vocal evidence; hybridizes with it in S of range (narrow zone between R Orange and Port Nolloth). Geographical variation linked to soil type (pale sands on coast, redder inland); differentiation marked in SW of range, with coastal patae replaced by inland cavei over distance of just a few kilometres and intermediates scarce; nomina..

Forms a superspecies with C. burra, C. albescens and C. erythrochlamys; sister-species to last of those, with no known range overlap between the two. Recently split from C. albescens on grounds of genetic, morphological and vocal evidence; hybridizes with it in S of range (narrow zone between R Orange and Port Nolloth). Geographical variation linked to soil type (pale sands on coast, redder inland); differentiation marked in SW of range, with coastal patae replaced by inland cavei over distance of just a few kilometres and intermediates scarce; nominate intergrades with latter race. Three subspecies recognized.
Subspecies and Distribution:
- barlowi (Roberts, 1937) - SW Namibia from S of R Koichab (inland of Lüderitz) E to Aus.
- patae (Macdonald, 1953) - coastal sands from SW Namibia (Lüderitz) to extreme NW South Africa (Port Nolloth).
- cavei (Macdonald, 1953) - inland part of coastal plain from extreme SW Namibia (S from Aus) to NW South Africa (R Holgat).
