The giant kingfisher (Megaceryle maxima) is the largest kingfisher in Africa, where it is a resident breeding bird over most of the continent south of the Sahara Desert, other than the arid southwest.
Taxonomy
[edit]The first formal description of the giant kingfisher was by the German naturalist Peter Simon Pallas in 1769 under the binomial name Alcedo maxima.[2] The current genus Megaceryle was erected by the German naturalist Johann Jakob Kaup in 1848.[3]
There are two subspecies:[4]
- M. m. maxima (Pallas, 1769) – Senegal and Gambia to Ethiopia and south to South Africa
- M. m. gigantea (Swainson, 1837) – Liberia to northern Angola and western Tanzania, island of Bioko
The nominate subspecies M. m. maxima occurs in wooded savanna while M. m. gigantea prefers tropical rainforest.[5]
Description
[edit]The giant kingfisher is 42–46 cm (16.5–18 in) long, with a large shaggy crest, a large black bill and fine white spots on black upperparts. The male has a chestnut breast band and otherwise white underparts with dark flank barring. The female has a white-spotted black breast band and a chestnut belly.[5] The forest race M. m. gigantea is darker, less spotted above, and more barred below than the nominate race, but the two forms intergrade along the forest edge zone.[5]
The call is a loud wak wak wak.
Behaviour
[edit]Breeding
[edit]In South Africa breeding takes place between September and January, in Zimbabwe from August to March, in Zambia March to April and in Liberia December to January.[5]
The giant kingfisher is monogamous and a solitary breeder. The nest is a long horizontal tunnel that is excavated into a river bank by both sexes using their feet and bills. The entrance hole is 11 cm (4.3 in) high and 15 cm (5.9 in) wide. The tunnel is typically 2 m (6 ft 7 in) in length but a tunnel of 8.5 m (28 ft) has been recorded. A clutch of around three eggs is laid in a chamber at the end of the tunnel.[5]
Feeding
[edit]This large species feeds on crabs, fish, and frogs, caught by diving from a perch.
