Adaptations for desert life

Burchell's sandgrouse is limited by water availability, like many of the other species residing in arid desert environments. Adult sandgrouse increase gular fluttering and panting for evaporative cooling when approaching the upper critical limit of their thermal neutral zone around 43.8°C. Another adaptation that adult Burchell's sandgrouse have developed is the transport of water in body feathers from a water source back to the nest to water their chicks. Upon arriving at a water source, adult Burchell's sandgrouse first rub their bellies on dry ground to ruffle up their belly feathers, increasing the amount of water the feathers can hold. They then wade into the water and bob up and down on a horizontal axis to soak up the water in their belly feathers. Males have been observed to hold an average of 22 ml of water, while females can carry an average of 9 ml. Once the water is gathered, Burchell's sandgrouse fly back to the nest and allow their chicks to drink water from their belly feathers.
