Dupont's lark (Chersophilus duponti) is a species of lark in the family Alaudidae of the monotypic genus Chersophilus. It is found in northern Africa and Spain.

Taxonomy and systematics

[edit]

Dupont's lark was originally described by Louis Pierre Vieillot in 1820 and placed in the genus Alauda.[2][3] It was named for the French naturalist Léonard Puech Dupont, who had collected the species and showed it to Vieillot.[4]

Subspecies

[edit]

Two subspecies are recognized:[5]

  • North-western Dupont's lark (C. d. duponti) - (Vieillot, 1824): Found in southern Spain, northern Morocco, northern Algeria and northern Tunisia
  • South-eastern Dupont's lark (C. d. margaritae) - (Koenig, AF, 1888): Originally described as a separate species in the genus Alaemon. Found from central Algeria to western Egypt

Description

[edit]

Like most other larks, Dupont's lark is an undistinguished looking species on the ground. It is 17–18 cm long, slim, with a long neck, long legs and a fine slightly curved bill. It has a thin pale crown stripe and a dark-streaked breast. The north-western Dupont's lark of Europe and north-west Africa is mainly brown-grey above and pale below. The south-eastern Dupont's lark, which occupies most of the rest of the African range, has rufous upperparts.

Vocalisations

[edit]

Its song is a repeated thin, melancholic whistling phrase, very ventriloquial (difficult to locate) and a nasal whistle given mainly at dawn and dusk or at night.

Distribution and habitat

[edit]

It breeds across much of northern Africa, from Algeria to Egypt, and in Spain and France.[1] It is a non-migratory resident. It is a species that commonly inhabits chaparral areas.[6] However, it experiences a 3.9% annual population decrease in Spain with a 32.8% decrease from 2008 to 2018, shifting its conservation status to vulnerable on the national level and endangered in the regions of Andalusia and Castile-León.[7]

Behaviour and ecology

[edit]

This is a very shy species, which runs for cover when disturbed. It is difficult to see while running among vegetation but it sometimes sings, standing upright on the edge of a low bush.

Breeding

[edit]
Chersophilus duponti duponti

This is a bird of open sandy semi-desert or steppe with some grass. Its nest is on the ground, with three or four eggs being laid. Its food is seeds and insects.
