Crested Kingfisher

Megaceryle lugubris

Large thickset kingfisher of fast-flowing streams in forested inland regions. Dense, fine barring gives it a silvery appearance at a distance; this finer patterning, along with its large, shaggy crest, distinguishes it from the similarly black-and-white Pied Kingfisher. Often uses exposed perches, such as telephone lines and tall snags, from which it often gives its loud rattling call.

识别特征

The crested kingfisher is a very large 41–43 cm (16–17 in) black and white kingfisher with a shaggy crest. It has evenly barred wings and tail. It lacks a supercilium and has a spotted breast, which is sometimes mixed with rufous.

分类信息

The first formal description of the crested kingfisher was by the Dutch zoologist Coenraad Jacob Temminck in 1834 under the binomial name Alcedo lugubris. The current genus Megaceryle was erected by the German naturalist Johann Jakob Kaup in 1848. Megaceryle is from the Ancient Greek megas, "great", and the existing genus Ceryle. The specific name lugubris is the Latin word for "mournful".<p>There are four subspecies:

迁徙
Vertical migration

行为

The nest is a burrow excavated into a vertical bank in a forest. It can be by a stream or a ravine or can be up to 1.5 km (0.93 mi) away from water. The burrow is dug by both sexes using their feet and bills. It is 10–15 cm (3.9–5.9 in) wide and 2–3 m (6 ft 7 in – 9 ft 10 in) in length. The clutch of 4-7 eggs is incubated only by the female. The nestlings are fed by both parents for around 40 days before they fledge.
