The spotted thick-knee (Burhinus capensis), also known as the spotted dikkop or Cape thick-knee, is a wader in the family Burhinidae. It is native to tropical regions of central and southern Africa.
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". [2] [3]
The spotted thick-knee is nocturnal and squats on the ground during the daytime, making it difficult to spot. It hunts exclusively on the ground, feeding on insects, small mammals and lizards.
It nests on the ground, lining a scrape with grasses, feathers, pebbles and twigs. The female typically lays two eggs, and males and females rear the offspring together, with both bringing food back to the nest. The birds will defend the nest and adopt a defensive pose with wings spread and tail cocked and will even peck an intruder. Sometimes they will fake injuries to lead predators away from the nest. [2] [3]
The spotted thick-knee is native to the grasslands and savannas of sub-Saharan Africa. Its range extends from Senegal, Mali and Mauritania in the west to Ethiopia, Kenya, Tanzania and South Africa in the east and south, and south Yemen. [1]
The spotted thick-knee has a very extensive range, and its population is believed to be stable. For these reasons, the IUCN has rated it as being of "Least Concern". [1]
The stone-curlews, also known as dikkops or thick-knees, consist of 10 species within the family Burhinidae, and are found throughout the tropical and temperate parts of the world, with two or more species occurring in some areas of Africa, Asia, and Australia. Despite the group being classified as waders, most species have a preference for arid or semiarid habitats.
The bush stone-curlew or bush thick-knee, also known as the Iben bird is a large, ground-dwelling bird endemic to Australia. Its favoured habitat is open plains and woodlands, where it stalks slowly at night in search of invertebrates such as insects. Its grey-brown coloration is distinguished by dark streaks, its eyes are large and legs are long. It is capable of flight, but relies on the camouflage of its plumage to evade detection during the day; the bush curlew adopts a rigid posture when it becomes aware of an observer. Both sexes care for two eggs laid on the bare ground, usually sited near bush in a shaded position or next to a fallen branch.
The Eurasian stone-curlew, Eurasian thick-knee, or simply stone-curlew is a northern species of the Burhinidae (stone-curlew) bird family.
The Senegal thick-knee is a stone-curlew, a group of waders in the family Burhinidae. Their vernacular scientific name refers to the prominent joints in the long yellow or greenish legs.
The pearl-spotted owlet is a small bird of prey found in sub-Saharan Africa. They belong to the Strigidae family, otherwise known as the typical owls or the true owls, which contains most species of owl. As part of the genus Glaucidium, or pygmy owls, they are commonly referred to as 'owlets' due to their diminutive size. Pearl-spotted owlets are brownish and heavily spotted white, with two distinct black false 'eyes' at the back of their head. They are often confused with an African barred owlet.
The double-striped thick-knee is a stone-curlew, a group of waders in the family Burhinidae. The vernacular name refers to the prominent joints in the long greenish-grey legs, and bistriatus to the two stripes of the head pattern.
The spotted harrier also known as the smoke hawk, is a large Australasian bird of prey belonging to the family Accipitridae.
The African grass owl is a species of owl in the barn owl family, Tytonidae.
The blue korhaan or blue bustard is a species of bird in the family Otididae which is native to South Africa. Its call is a series of frog-like croaks, usually uttered in flight. Its natural habitat is plateau grassland, dry shrubland, arable land and pastureland. Its preferred habitat is one with short grassland and flat topography.
The Peruvian thick-knee is a species of bird in the family Burhinidae. It is found in Chile, Ecuador, and Peru. Its natural habitats are subtropical or tropical dry shrubland, subtropical or tropical seasonally wet or flooded lowland grassland, and pastureland. It is a ground-dwelling bird and feeds on insects and small animals.
Burhinus is a genus of birds in the family Burhinidae. This family also contains the genus Esacus. The genus name Burhinus comes from the Greek bous, ox, and rhis, nose.
The water thick-knee or water dikkop is a species of bird in the thick-knee family Burhinidae. The species is found across sub-Saharan Africa, usually close to water.
The Milnerton Racecourse Nature Reserve is a lowland conservation area located in the City of Cape Town, South Africa.
