Sandgrouse: Pterocliformes

Sandgrouse vary in size from 9.8 to 19 inches (25 to 48 centimeters) in length and 4.6 to 19.4 ounces (130 to 550 grams) in weight. Sandgrouse are generally colored to blend into their environments. Females and males have different coloration in most species, with females being colored more similarly to their environments. Sandgrouse are also characterized by extremely dense down that is well suited to their sometimes cold habitats. Some sandgrouse have partially feathered legs, while other species have feathers covering all of their legs and toes. Sandgrouse have short legs and long, pointed wings. They are good runners and extremely good fliers.
