Burhinus is a genus of birds commonly known as thick-knees. They are characterized by their long legs, large eyes, and distinctive thickened knees, which give them their name. These birds are typically found in open habitats such as grasslands, savannas, and shorelines, where they hunt for insects and small invertebrates. Thick-knees are mostly nocturnal, meaning they are active at night. They have a unique way of blending into their surroundings, using their cryptic plumage to avoid predators. There are several species within the Burhinus genus, each adapted to different environments across the world.
