Taxonomy

The first

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

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.

The call is a loud wak wak wak.

Behaviour

Breeding

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

This large species feeds on crabs, fish, and frogs, caught by diving from a perch.
