Birds
Sandgrouse
Pterocles spp. · also called sandgrouses
At a desert waterhole at first light, a male sandgrouse wades in and soaks his belly feathers thoroughly, then lifts off on a long flight home, carrying the only water his chicks will get all day.
Overview
Sandgrouse, genus Pterocles, are ground-dwelling birds of desert and semi-arid habitat across Africa, the Middle East, and Asia. Their uniquely water-absorbing belly feathers, used to carry drinking water back to chicks too young to travel, make them one of the more remarkable parental adaptations found in any desert bird.
A built-in canteen for the next generation
Where most desert birds simply endure long dry stretches, the sandgrouse solves the problem for its offspring directly, turning its own feathers into a portable water source that no other bird family relies on in quite the same way.
Status
Least Concern — widespread and common across suitable arid habitat throughout Africa, the Middle East, and Asia.
Sandgrouse: common questions
How does a male sandgrouse carry water to his chicks?
A male sandgrouse has uniquely structured belly feathers capable of absorbing and holding a substantial amount of water, which he soaks at a waterhole, sometimes tens of kilometres from the nest, before flying home so his chicks can drink directly from the water held in his feathers.
Can sandgrouse chicks travel to water themselves?
No, although sandgrouse chicks can walk and begin feeding themselves shortly after hatching, they cannot yet travel the often considerable distance to a reliable waterhole, which is why they remain dependent on water carried back to them in a parent's specialised belly feathers.
Why do sandgrouse gather at waterholes in such large numbers?
Sandgrouse frequently arrive at a dependable waterhole in large, tightly synchronised flocks at predictable times of day, usually early morning, a pattern that likely helps dilute individual risk from predators waiting near the exposed, open water's edge.
Where do sandgrouse live?
Sandgrouse species are found across desert and semi-arid habitat throughout Africa, the Middle East, and parts of Asia, generally in open, sparsely vegetated terrain where cryptic, sandy-toned plumage provides effective camouflage.
