Burhinidae is a family of birds commonly known as thick-knees. They are characterized by their long legs, large eyes, and a distinctive, thickened knee joint. 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, using their excellent night vision to forage for food. They are known for their unique calls, which can sound like a human's laughter. There are several species within the Burhinidae family, and they are distributed across various regions, including Africa, Asia, and Australia.
