Spotted Thick-knee
Burhinus capensis
The spotted thick-knee, which can reach up to 45.5 cm (17.9 in) in height, has long legs and brown-and-white speckled plumage which provides camouflage, making it difficult to spot the bird in the grasslands and savannas where it roams. Its head is large and round with a prominent yellow eye and a short, stout beak. When in flight or standing in a characteristic position with its wings raised, it shows a striking contrasting pattern. Its legs are long and yellow and the tibiotarsal joint is expanded, giving it the name "thick-knee".

The wings are broad and blunt and the tail is short. Its legs are pale greenish yellow, and the iris colour greenish yellow with black tracing.
