What is a Water Dikkop?

The Water Dikkop, or also known as the Water Thick-Knee and Burhinus vermiculatus, is a species of bird that is categorized in the think-knee or stone-curlews family Burhindae. This family of bird species consists of medium to large birds, usually with bulging yellow eyes and yellow or black bills that give off a reptilian appearance. The bird species under the Burhindae family are present all over the world and are mainly nocturnal.

Its binomial name Burhinus vermiculatus came from the Greek word “Burhinus,” meaning a massive nose and Latin word “vermiculatus,” which means “decorated with worm-like markings and tracings.”

The Water Dikkop is endemic to sub-Saharan Africa, and they usually take refuge near water sources. Since there are no present threats that may jeopardize the Water Dikkop’s population in the African continent, the International Union for Conservation of Nature (ICN) Red List categorized this species as “Least Concern.” This categorization is given to certain species that are nowhere near extinction.

The behavior of a Water Dikkop

A Water Dikkop is a terrestrial feeder that hunts for food at night. It mainly feeds on insects, mollusks, termites, small fish, frogs, tadpoles, and crustaceans. This bird is highly nocturnal, but it can be very vocal during the daytime. Its cry sounds like “ti-ti-ti.”

Water Dikkops are excellent flyers. However, when faced with a threat, it prefers to use its long, strong legs to run than use its wide black wings to fly.

The Water Dikkops breed during the dry season and pre-rainy season. They are highly monogamous and solitary nesters. They create nests using a simple scrape on the muddy ground, which is outlined with dry mud, stone chips, and fallen leaves. Their nests are situated by the edge of a water source or near animal dung.

A female Water Dikkop lays 1-3 eggs during August-January. Both male and female Water Dikkops incubate these eggs for 22-25 days. Their eggs are off white in color with brown streaks.

Fascinating facts about Water Dikkops

Despite their small figures, did you know that the Water Dikkops is deemed to be the bravest birds in the world because it likes living with one of the world’s greatest predators, the Nile Crocodiles?
