What You'll Learn
Water thick-knees lay 1-3 eggs at a time
Water thick-knees, also known as water dikkops, are a species of bird in the thick-knee family Burhinidae. They are found across sub-Saharan Africa, inhabiting riverbanks, lake shores, estuaries, swamps, mangroves, and occasionally beaches. They prefer to nest on sandbars in low-flowing rivers or on the shores of other water bodies.
During the breeding season, water thick-knees lay 1-3 eggs at a time. Both parents take turns incubating the eggs for just over three weeks, and the chicks fledge at about two months old. The eggs are sandy-yellow in colour and are well-camouflaged in their environment.
The water thick-knee is unique among birds in that it frequently nests adjacent to or directly on top of Nile crocodile nests. This symbiotic relationship benefits both species, as the vocal and energetic thick-knees act as sentries for the nests, while the powerful crocodiles provide protection.
In addition to their distinctive nesting behaviour, water thick-knees are also known for their nocturnal habits and their preference for hunting at night. They have a varied diet, including invertebrates such as insects, crustaceans, molluscs, tadpoles, and frogs, as well as seeds.
Overall, the water thick-knee is an interesting bird species with unique characteristics and behaviours that contribute to its successful reproduction and survival in its natural habitat.

Both male and female water thick-knees incubate the eggs
The water thick-knee, or water dikkop, is a nocturnal bird species found in sub-Saharan Africa, inhabiting riverbanks, lake shores, swamps, estuaries, and occasionally beaches. The species generally breeds during the dry season or early rainy season, and both male and female water thick-knees play a role in incubating the eggs and guarding the nest.
Water thick-knees are monogamous breeders, with both parents involved in the nesting and brooding process. The nest is typically a simple scrape in sandy or stony ground, usually located close to water. The clutch size is two sandy-yellow eggs, which are well-camouflaged in their environment.
Both male and female water thick-knees share the responsibility of incubating the eggs for 22 to 25 days. During this period, the parents take turns sitting on the eggs to keep them warm and protected. After the incubation period, the chicks hatch and remain in the nest for about two months before fledging.
The male and female water thick-knees also collaborate in feeding their young. This teamwork in both incubating the eggs and caring for the chicks ensures the survival and well-being of the offspring. The breeding season for water thick-knees usually coincides with the end of the dry season, when they prefer to nest on sandbars in low-flowing rivers or on the shores of other water bodies.
The water thick-knee is a unique bird species, and its breeding behaviour showcases the dedication of both parents to the care and protection of their young. By sharing the responsibilities, the male and female water thick-knees maximise the chances of their chicks' survival in their natural habitat.

Water thick-knees have a unique symbiotic relationship with crocodiles
The water thick-knee, or water dikkop, is a nocturnal bird species found in sub-Saharan Africa, usually close to water. They inhabit riverbanks, lake shores, estuaries, swamps, and occasionally beaches with sufficient shrub and bush cover. They are known for their unique nesting behaviour, wherein they lay their eggs adjacent to or directly on top of Nile crocodile nests. This nesting behaviour gives rise to a symbiotic mutualistic relationship between the two species.
Water thick-knees have a mutually beneficial relationship with crocodiles, particularly the Nile crocodile. This relationship is a form of symbiotic mutualism, where both species benefit from their proximity and interactions. The water thick-knee, being more energetic and vocal, acts as a sentry for its nest and the neighbouring crocodile nest. Its loud, distinctive calls serve as an early warning system, alerting the crocodile of potential threats. The crocodile, in turn, provides protection for the nests with its powerful presence and defensive capabilities.
The water thick-knee's role as a vigilant guardian is crucial in this symbiotic partnership. When a nest raider approaches, the thick-knee pair actively defends the nests by spreading their wings in a threatening display, harassing, and pecking at the intruder to drive it away. Their vocalisations not only warn the crocodile but also help to protect their own chicks from potential harm. This protective behaviour is especially important during the breeding season, which typically coincides with the end of the dry season.
The water thick-knee's nesting behaviour of laying their eggs near or directly on crocodile nests provides several advantages. Firstly, it ensures maximum protection for their own chicks, as the crocodiles deter potential predators or raiders. Secondly, the proximity to water allows the water thick-knees easy access to their aquatic diet, which includes invertebrates, insects, crustaceans, molluscs, tadpoles, frogs, and seeds. This symbiotic relationship showcases the unique ways in which different species can cooperate and benefit from each other's strengths.
Overall, the water thick-knee and crocodile's symbiotic relationship is a fascinating example of nature's unexpected partnerships. By working together, these two seemingly unlikely allies maximise their chances of survival and successfully protect their young. This relationship highlights the intricate and dynamic interactions that can arise between different species in the natural world.

Water thick-knees guard their chicks
Water thick-knees are monogamous breeders, with both parents guarding the nest and brooding the eggs. The nest is usually a simple scrape in the ground, adjacent to a rock or piece of driftwood, and the eggs and chicks are well-camouflaged. The female and male thick-knees take turns incubating the eggs, which range from one to three in number.
Water thick-knees are protective parents. They have a unique nesting behaviour, often choosing to lay their eggs adjacent to or directly on top of Nile crocodile nests. This symbiotic mutualism provides benefits for both species. The more energetic and vocal thick-knees act as sentries for the nests, while the crocodiles offer protection. In the event of a nest raider, the thick-knee pair will attempt to drive off the intruder by spreading their wings in a threat display and harassing and pecking at them.
The Cape thick-knee, a member of the Burhinidae family, is also protective of its chicks. If their eggs or chicks are threatened, the male and female will distract the predator by flopping on the ground.
Water thick-knees are found across sub-Saharan Africa, typically near water, in countries such as Angola, Botswana, and South Africa. They are nocturnal birds, hunting at night and hiding during the day in deep shade near water.

Water thick-knees nest in sand bars in rivers or shores of water bodies
The water thick-knee, or water dikkop, is a nocturnal bird species that inhabits riverbanks, lake shores, swamps, estuaries, and occasionally beaches with sufficient cover in the form of shrubs and bushes. They are found in sub-Saharan Africa, usually close to water, and have a wide, albeit patchy, distribution. They weigh about 300 grams, with a wingspan of about 75 centimetres. Their diet includes invertebrates like insects, crustaceans, molluscs, tadpoles, frogs, and seeds.
Outside of the breeding season, the water dikkop congregates in groups of up to 30 birds. The breeding season usually coincides with the end of the dry season, and they prefer to nest on sandbars in low-flowing rivers or on the shores of other water bodies. The nest is just a simple scrape in the sandy or stony ground, usually close to water, and the eggs and chicks are superbly camouflaged.
Typically, 1-3 eggs are incubated by both parents for just over three weeks, with the chicks fledging at about two months old. The water thick-knee is a monogamous breeder, with both parents guarding the nest and brooding the eggs. Interestingly, thick-knee pairs frequently nest adjacent to, and sometimes directly on top of, Nile crocodile nests. This unique relationship between the two species is symbiotic, with the more energetic and vocal thick-knees functioning as loud sentries for the nests, while the powerful crocodiles provide protection.
The water thick-knee is a terrestrial feeder that forages at night, typically associated with water, but it can be found foraging up to 1 kilometre away from it. It feeds on insects, crustaceans, molluscs, and other small creatures.
