Thick-Knees: Burhinidae

Physical Characteristics

Thick-knees vary in size from 12.5 to 23 inches (32 to 59 centimeters) in length and 0.7 to 2.4 pounds (0.3 to 1.1 kilograms) in weight. Their heads are round, their necks are slender, and their bodies are large. Thick-knees have long legs, long tails, and a pointed bill. All thick-knees have large yellow or amber colored eyes and stripes either above the eyes, through the eyes, or below the eyes. Most species are a light sandy brown on top and pale on the belly. The wings are either solid-colored, striped, or spotted while folded. When thick-knees are flying, however, striking black and white patterns on the wings and tail are revealed. Males and females tend to be similar in both size and color. Young thick-knees are colored to blend into their stony or sandy habitats.
