The dune lark is the only avian creature that has evolved the ability to survive in the Namib Desert, which is one of the driest regions in the world.
Taxonomy
The dune lark was formally described in 1853 by the English naturalist Hugh Strickland based on specimens collected in Damaraland, a coastal belt near Walvis Bay in Namibia. He coined the binomial name Alauda erythrochlamys.[2][3] The dune lark is now one of eight larks placed in the genus Calendulauda that was introduced by the English zoologist Edward Blyth in 1855.[4] The name Calendulauda combines the names of two other lark genera: Calendula and Alauda.[5] The specific epithet erythrochlamys combines Ancient Greek ερυθρος/eruthros meaning "red" with χλαμυς/khlamus, χλαμυδος/khlamudos meaning "cloak".[6]
Four subspecies are recognised:[4]
- C. e. erythrochlamys (Strickland, 1853) – Kuiseb River (Walvis Bay) to Koichab River (central west Namibia)
- C. e. barlowi (Roberts, 1937) – Koichab River to Aus (southwest Namibia)
- C. e. patae (Macdonald, 1953) – coastal southwest Namibia to northwest South Africa
- C. e. cavei (Macdonald, 1953) – inland southwest Namibia to northwest South Africa
Barlow's lark (Calendulauda barlowi) (including patae and cavei) was formerly considered to be a separate species. It is now lumped with the dune lark based on the very shallow genetic divergence and the essentially identical size and vocalizations.[4][7][8]
