The sand grouse is a bird that lives in deserts.  They drink water in flocks of as many as 80,000 birds swallowing until full without pausing. They must have water daily and may fly for more than 121 km a day in search of water. They are strong flyers.  On the ground, the sand grouse waddle on their short, feathered legs.  They don't have a first toe, so they do not perch. They eat berries and seeds and insects.  They lay their eggs in shallow ground nests. Males have feathers of the belly that are adapted to absorbing water and retaining it, allowing them to carry water to chicks that may be many  kilometers away from watering holes.
