Taxonomy:
Order Coraciiformes
Family Alcedinidae

Range:
These birds are found throughout most of sub-Saharan Africa, with the exception of the arid areas of Namibia, Botswana and north-western South Africa, and northern Kenya, eastern Ethiopia and Somalia.

Size:
The giant kingfisher is 42-48 cm long and 255-425 g.

Habitat:
The giant kingfisher is found in large perennial rivers, and in lakes and dams with plenty of marginal woody growth, also using moist tropical forests, swamp forests, mangroves, and estuaries and other intertidal habitats.

Diet:
They mainly hunt fishes, particularly cichlids and groupers, but also take river crabs, frogs, toads and, occasionally, small reptiles and insects. 

Breeding:
Giant kingfishers breed in August-March, varying among different parts of their range. They nest in solitary pairs, with both sexes helping excavate the nest tunnel in a river bank, cliff or sand quarry. The tunnel can be up to 1,8 m long and has an unlined nest chamber at the end. There the female lays 3-5 white eggs which are incubated by both parents for 25-27 days. The chicks fledge about 37 days after hatching, but only become fully independent 3 weeks later.

Conservation:
IUCN status - LC (Least Concern)
This species has an extremely large breeding range and is reported to be widespread and common in some areas. The population is suspected to be in decline, possibly owing to loss of nesting sites and the effects of pesticide run-off from adjacent farmland. It is also shot as a pest at some trout hatcheries.

Common name:
rufous-collared kingfisher (en); guarda-rios-de-coleira-ruiva (pt); martin-chasseur trapu (fr); alción malayo (es); Malaienliest (de)

Taxonomy:
Order Coraciiformes
Family Alcedinidae

Range:
This species is found from extreme southern Myanmar and Thailand, across the Malay Peninsula, and into Borneo, Sumatra and adjacent islands in Indonesia.

Size:
These birds are 23-24 cm long and weigh 60-90 g.

Habitat:
The rufous-collared kingfisher is mainly found in the understorey and mid-storey of tropical rainforests, also using tall, regenerating logged forests. They are present from sea level up to an altitude of 1.700 m.

Diet:
They feed mainly on large arthropods, including isopods, cicadas, beetles, mantids, spiders and scorpions, but also take fish, snails, small snakes and lizards.

Breeding:
Rufous-collared kingfishers breed in December-June. They are monogamous and both sexes participate in burrow excavating the nest burrow, located on a low bank or man-made ditch, usually near a stream. The female lays 2 eggs which are incubated for about 22 days. There is no available information on the fledgling period.

Conservation:
IUCN status - NT (Near-Threatened)
This species has a very large breeding range, but is suspected to be declining at a moderate rate as a result of deforestation. Rates of forest loss in the Sundaic lowlands have been extremely rapid, owing partly to the escalation of illegal logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas. Forest fires have also had a damaging effect. The magnitude of these threats may be allayed by this species tolerance of hill forests, which are under less pressure from logging and agricultural conversion.
