The Malachite Kingfisher (Corythornis cristatus) is a diminutive and vibrant river kingfisher, with a length of approximately 13 cm. It boasts a striking metallic blue on its upper parts and a rufous underbelly, with a distinctive black and blue crest adorning its head. The bird's bill transitions from black in its youth to a reddish-orange hue in adulthood, and it stands on bright red legs. Both sexes appear similar, though juveniles present a more subdued version of the adult's plumage.
When identifying the Malachite Kingfisher, look for its short crest and the contrast between the rufous face and underparts against the bright blue upper parts. The white throat patch and the red bill and legs are also key features. The bird's rapid, low flight over water, with wings a blur, is characteristic.
This species is commonly found amongst reeds and aquatic vegetation adjacent to slow-moving waters or ponds. It thrives in a variety of wetland habitats across Sub-Saharan Africa.
The Malachite Kingfisher is widely distributed across Sub-Saharan Africa, with its range extending from Senegal to South Africa. It is largely sedentary, with movements influenced by seasonal changes in climate.
The Malachite Kingfisher is known for its rapid flight, often skimming low over the surface of the water. It typically perches close to the water's edge, ready to dive for its prey.
The vocalizations of the Malachite Kingfisher include a variety of high-pitched, piercing calls, often heard during its undulating flight or when perched.
Nesting occurs in tunnels excavated within sandy banks, often positioned above water. Both parents partake in burrow construction, which tends to slope upward before reaching the nesting chamber. The species may lay three to six round, white eggs per clutch, with up to four clutches per breeding season. The eggs rest on a bed of fish bones and regurgitated pellets.
The Malachite Kingfisher is an adept hunter, often seen perched before plunging into the water to catch fish, aquatic insects, and crustaceans. It may beat larger prey on a branch before consumption, while smaller catches are swallowed whole.
The IUCN Red List classifies the Malachite Kingfisher as Least Concern, indicating a stable population across its extensive range.
