Kingfishers are
a group of small to medium sized brightly colored birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species found outside of the Americas. The
group is treated either as a single family, Alcedinidae, or as a suborder Alcedines containing
three families, Alcedinidae (river kingfishers), Halcyonidae (tree kingfishers), and Cerylidae (water kingfishers). There are roughly 90 species of kingfisher. All have
large heads, long, sharp, pointed bills, short legs, and stubby tails. Most
species have bright plumage with little differences between the sexes. Most species
are tropical in distribution, and slight majorities are found only in forests.
They consume a wide range of prey as well as fish, usually caught by swooping
down from a perch. While kingfishers are usually thought to live near rivers
and eat fish, most of the kingfisher species in the world live away from water
and eat small invertebrates. Like other members of their order they nest in
cavities, usually tunnels dug into the natural or artificial banks in the
ground. A quarter of all kingfishers nest in disused termite nests. A few
species, principally insular forms, are threatened with extinction. In Britain, the word 'kingfisher' normally
refers to the common
kingfisher.
In Sri Lanka we have seven species of
kingfishers. They are the Pied Kingfisher (Ceryle rudis), the Common Kingfisher
(Alcedo atthis), the Blue-eared Kingfisher (Alcedo meninting), the Oriental dwarf Kingfisher (Ceyx erithacus), the Stork-billed
Kingfisher (Pelargopis capensis), the White-breasted Kingfisher (Halcyon smyrnensis)
and the Black-capped Kingfisher (Halcyon pileata)
Pied Kingfisher
The pied
kingfisher (Ceryle rudis) is a water kingfisher and is
found widely distributed across Africa and Asia. Its black and white plumage,
crest and the habit of hovering over clear lakes and rivers before diving for
fish makes it distinctive. Males have a double band across the breast while
females have a single gorget that is often broken in the middle. They are
usually found in pairs or small family parties. When perched, they often bob
their head and flick up their tail. This kingfisher is about 17 cm
long and is white with a black mask, a white supercilium and black breast
bands. The crest is neat and the upperparts are barred in black. Several
subspecies are recognized within the broad distribution. The nominate race is
found in sub-Saharan Africa, extending into West Asia. A former subspecies syriaca is
considered as merely a larger northern bird of the nominate species. Subspecies leucomelanura is
found from Afghanistan east into India, Sri Lanka, Thailand and Laos. The
subspecies travancoreensis of the Western Ghats is darker with
the white reduced. Subspecies C. r. insignis is found in Hainan and southeastern
China and has a much larger bill. Males have a narrow second breast-band while
females have a single broken breast band.
Common Kingfisher
The common kingfisher (Alcedo atthis) also known as
Eurasian kingfisher, or river kingfisher, is a small kingfisher with seven subspecies recognized
within its wide distribution across Eurasia and North
Africa. It is resident in much of its range, but migrates from areas where rivers
freeze in winter.
This sparrow-sized bird has the typical short-tailed,
large-headed kingfisher profile; it has blue upperparts, orange underparts and
a long bill. It feeds mainly on fish, caught by diving, and has special visual
adaptions to enable it to see prey under water. The glossy white eggs are laid
in a nest at the end of a burrow in a riverbank.
This species has the typical short-tailed, dumpy-bodied
large-headed and long-billed kingfisher shape. The adult male of the western
European subspecies, A.
a. ispida has green-blue upperparts with pale azure-blue
back and rump, a rufous patch by the bill base, and a rufous ear-patch. It has
a green-blue neck stripe, white neck blaze and throat, rufous underparts, and a
black bill with some red at the base. The legs and feet are bright red. It is about 16 centimeters
(6.3 in) long with a wingspan of 25 cm (9.8 in), and
weighs 34–46 grams (1.2–1.6 oz.)
Blue
Eared Kingfisher
The blue-eared kingfisher (Alcedo
meninting) is found in Asia, ranging across the Indian
subcontinent and Southeast
Asia. It is found mainly in dense shaded forests
where it hunts in small streams. It is darker crowned, with darker rufous
underparts and lacking the rufous ear stripe of the common kingfisher (Alcedo atthis) which is found in more open habitats. A number
of subspecies have been described that differ in measurement and colour shade.
Adult males have an all dark bill while females have a reddish lower mandible.
This
16 centimeters (6.3 in) long kingfisher is almost identical to the common
kingfisher (Alcedo atthis) but is distinguished by the blue ear coverts,
darker and more intense cobalt-blue upperparts with richer rufous under parts.
The juvenile blue-eared kingfisher has rufous ear-coverts as in the common
kingfisher but it usually shows some mottling on the throat and upper breast
which disappears when the bird reaches adulthood. Young birds have a reddish
bill with whitish tips.
Oriental dwarf Kingfisher
The Oriental
dwarf kingfisher (Ceyx erithaca) also known as the black-backed
kingfisher or three-toed kingfisher is a species of bird in
the Alcedinidae family. This is a small, red and yellow
kingfisher, averaging 13 cm (5.1 in) in length, yellow underparts
with glowing bluish-black upperparts. This is a widespread resident of lowland
forest, endemic across much of the Indian
subcontinent and Southeast
Asia. It is found in Bangladesh, Bhutan, Brunei, Cambodia, India, Indonesia, Laos, Malaysia, Myanmar, Singapore, Sri
Lanka and Thailand. The preferred habitat is small streams in
densely shaded forests. In the Konkan region of southwest India, it begins to breed with the
onset of the Southwest
Monsoon in June. The nest is a horizontal tunnel up to a meter in
length. The clutch of 4-5 eggs hatches in 17 days with both the male and female
incubating. The birds fledge after 20 days and a second brood may be raised if
the first fails. The young are fed with geckos, skinks, crabs, snails, frogs,
crickets and dragonflies. The rufous-backed
kingfisher is sometimes considered a subspecies.
Stork-billed
Kingfisher
The stork-billed kingfisher (Pelargopsis
capensis) (formerly Halcyon
capensis), is a tree kingfisher which is widely but sparsely distributed in the tropical Indian subcontinent and Southeast
Asia, from India to Indonesia. This kingfisher is essentially resident throughout its range. This
is a very large kingfisher, measuring 35 to 38 cm (14 to 15 in) in
length. The adult has a green back, blue wings and tail, and grey
head. Its underparts and neck are buff. The very large bill and legs are bright
red. The flight of the stork-billed kingfisher is labored and flapping, but
direct. Sexes are similar. There are 15 races, mostly differing in plumage
detail, but P. c. giganteaof
the Sulu Islands has a white head, neck and underparts. The call of this noisy
kingfisher is a low and far reaching peer-por-por repeated every 5 seconds or so as well
cackling ke-ke-ke-ke-ke-ke.
Stork-billed
kingfisher is a species of a variety of well-wooded habitats near lakes, rivers
or coasts. It perches quietly whilst seeking food, and is often inconspicuous
despite its size. It is territorial and will chase away eagles and other large predators. This
species hunts fish, frogs, crabs, rodents and young birds.
Stork-billed
kingfisher digs its nest in a river bank, decaying tree, or a tree termite
nest. A clutch of two to five round white eggs is typical.
White Breasted Kingfisher
The white-throated
kingfisher (Halcyon smyrnensis) also known as the white-breasted
kingfisher or Smyrna kingfisher,
is a tree kingfisher, widely distributed
in Eurasia from Bulgaria, Turkey, West
Asia east through the Indian
subcontinent to the Philippines. This kingfisher is a resident over much of its range, although some
populations may make short distance movements. It can often be found well away
from water where it feeds on a wide range of prey that includes small reptiles,
amphibians, crabs, small rodents and even birds. During the breeding season
they call loudly in the mornings from prominent perches including the tops of
buildings in urban areas or on wires.
This is a large kingfisher, 28 cm in
length. The adult has a bright blue back, wings and tail. Its head, shoulders,
flanks and lower belly are chestnut, and the throat and breast are white. The
large bill and legs are bright red. The flight of the white-throated kingfisher
is rapid and direct, the short rounded wings whirring. In flight, large white
patches are visible on the blue and black wings. Sexes are similar, but
juveniles are a duller version of the adult.
White-throated kingfisher is a common species of a variety
of habitats, mostly open country in the plains (but has been seen at
7500 ft in the Himalayas) with trees, wires or other perches. The range of
the species is expanding.
This
kingfisher is widespread and populations are not threatened. Average density of
4.58 individuals per km2. Has been noted in the Sundarbans mangroves.
Black Capped Kingfisher
The black-capped kingfisher (Halcyon pileata) is a tree kingfisher which is widely distributed in
tropical Asia from India east to China, Korea and Southeast Asia. This most
northerly of the Halcyonidae is resident over much of its range, but northern
populations are migratory and the
wintering range extends to Sri
Lanka, Thailand, Borneo and Java.
This
is a large kingfisher, 28 cm in length. The adult has a purple-blue back,
black head and shoulders, white neck collar and throat, and rufous underparts.
The large bill and legs are bright red. In flight, large white patches are
visible on the blue and black wings. Sexes are similar, but juveniles are a
duller version of the adult. The call of this kingfisher is a cackling ki-ki-ki-ki-ki.
This
is a common species on coastal waters especially in mangroves. Although easily
disturbed, it perches conspicuously on wires or other exposed perches. This
species mainly hunts large insects, but coastal birds will also take fish and
frogs. The flight of the black-capped kingfisher is rapid and direct, the short
rounded wings whirring.
The
nest is a tunnel in an earth bank. A single clutch of 4-5 round white eggs is
typical.
