Breeds on dry steppes of Kazakhstan and southern Russia; migrates to winter in sub-Saharan Africa. NT. Aerial insectivore. Declining due to steppe cultivation. Long-distance migrant.

Double-banded Courser

Double-banded Courser: 20–22 cm, pale sandy-brown courser with two black breast-bands and a white supercilium. Resident in arid stony plains and dry open savanna of eastern and southern Africa. Nocturnal and crepuscular insectivore, resting in shade during hot midday. Cryptic plumage provides camouflage on stony ground. Sedentary.
