Common name:
short-clawed lark (en); cotovia-d'unhas-curtas (pt); alouette à ongles courts (fr); alondra chuana (es); akazien-langschnabellerche (de)
Taxonomy:
Order Passeriformes
Family Alaudidae
Range:
This African species is only found in south-eastern Botswana and north-eastern South Africa.
Size:
These birds are 14-17 cm long and weigh 44 g.
Habitat:
Short-clawed larks are found in dry savannas, preferring semi-arid Acacia savanna with scattered grass clumps and bushes, and large patches of bare ground.
Diet:
They are strictly insectivorous, taking grasshoppers, weevils, Anoplolepis ants, Hodotermes and Macrotermes termites, and caterpillars.
Breeding:
Short-clawed larks breed in September-March. The nest is built solely by the female, consisting of an open cup built of grass and lined with finer plant material. It is typically placed in a scrape in the ground beneath a grass tuft or small shrub. The female lays 2-3 eggs, which she incubates alone for 14-16 days. The chicks are fed by both parents and fledge 11-12 days after hatching, but remain with their parents for another 4 weeks.
Conservation:
IUCN status - LC (Least Concern)
This species has a restricted breeding range and a global population estimated at 50.000-100.000 individuals. The population seems to be stable in its core breeding areas, in Botswana, but some declines have been reported in South Africa.
