Thewhite-throated kingfisher (Halcyon smyrnensis) also known as thewhite-breasted kingfisher is atree kingfisher, widely distributed inAsia from theSinai east through theIndian subcontinent toChina andIndonesia. Thiskingfisher 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 smallreptiles,amphibians,crabs, smallrodents and evenbirds. During the breeding season they call loudly in the mornings from prominent perches including the tops of buildings in urban areas or on wires.
The white-throated kingfisher is one of the many birds that were firstformally described by the Swedish naturalistCarl Linnaeus in 1758 in thetenth edition of hisSystema Naturae. He coined thebinomial nameAlcedo smyrnensis.[2][3] Linnaeus citedEleazar Albin'sNatural History of Birds published in 1738 that included a description and a plate of the "Smirna Kingfisher".[4] Albin's specimen was preserved in alcohol and had been collected by the botanistWilliam Sherard who served as the British Consul atSmyrna between 1703 and 1716.[4][5] The present genusHalcyon was introduced by the English naturalist and artistWilliam Swainson in 1821.[6]Halcyon is a name for a bird in Greek mythology generally associated with thekingfisher. The specific epithetsmyrnensis is an adjective for the city ofSmyrna (nowİzmir in Turkey).[7]
H. s. fokiensis Laubmann & Götz, 1926 – south and east China, Taiwan andHainan
Thebrown-breasted kingfisher (H. gularis) of thePhilippines is usually now considered as a separate species.[9][10] Support for this treatment was provided by a molecular study published in 2017 that found thatH. s. gularis was more closely related to theJavan kingfisher (H. cyanoventris) than it was to the white-throated kingfisher.[11] They were split as distinct species by theIUCN Red List andBirdLife International in 2014, and theInternational Ornithological Congress followed suit in 2022.[12] The racesH. s. perpulchra andH. s. fokiensis are sometimes included inH. s. fusca.[13]
Local names include Baluchistan:aspi chidok; Sindhi:dalel; Hindi:kilkila,kourilla; Himachal Pradesh:neela machhrala; Punjabi:wadda machhera; Bengali:sandabuk machhranga; Assamese:māsorokā, মাছৰোকা; Cachar:dao natu gophu; Gujarati:kalkaliyo,safedchati kalkaliyo; Marathi:khundya; Tamil:vichuli; Telugu:lakmuka,buchegadu; Malayalam:ponman; Kannada: Minchulli(ಮಿಂಚುಳ್ಳಿ),rajamatsi; Sinhalese:pilihuduwa.[14]
This is a large kingfisher, 27–28 cm (10.6–11.0 in) 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.[15]
This species forms a superspecies withHalcyon cyanoventris and most major works recognize four geographic races. They vary clinally in size, the shades of blue on the mantle which is more greenish insmyrnensis andfusca and more blue or purplish insaturatior.H. s. gularis of the Philippines has only the neck and throat white. It is sometimes treated as a distinct species,H. gularis. Racefusca is found in Peninsular India and Sri Lanka and is slightly smaller, bluer and with a darker brown underside than the nominate race found in northwestern India. Racesaturatior is found in theAndaman Islands and is larger with darker brown underparts. Raceperpulchra (not always recognized) is found in northeastern India and is smaller thanfusca with paler underparts.[16] Albinism has been noted on occasion.[17]
The white-throated kingfisher is a common species in a variety of habitats, mostly open country in the plains (but has been seen at 7500 ft in the Himalayas[18]) 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 theSundarbans mangroves.[19]
The white-throated kingfisher begins breeding at the onset of theMonsoons. Males perch on prominent high posts in their territory and call in the early morning. The tail may be flicked now and in its courtship display the wings are stiffly flicked open for a second or two exposing the white wing mirrors. They also raise their bill high and display the white throat and front. The female in invitation makes a rapid and prolongedkit-kit-kit... call. The nest is a tunnel (50 cm long, but a nest with a 3-foot tunnel has been noted[20]) in an earth bank. The nest building begins with both birds flying into a suitable mud wall until an indentation is made where they can find a perch hold. They subsequently perch and continue digging the nest with their bills. Nest tunnels in a haystack have also been recorded.[21] A single clutch of 4–7 round whiteeggs is typical. The eggs take 20–22 days to hatch while the chicks fledge in 19 days.[22][23][24]
It perches conspicuously on wires or other exposed perches within its territory, and is a frequent sight in south Asia. This species mainly hunts large crustaceans,[25] insects, earthworms,[26] rodents, lizards,[27][28][29] snakes, fish and frogs.[30][31] Predation of small birds such as theIndian white-eye, chick of ared-wattled lapwing, sparrows and munias have been reported.[22][32][33] The young are fed mostly on invertebrates.[34] In captivity, it has been noted that it rarely drinks water although bathing regularly.[35]
With a powerful bill and rapid flight, these kingfishers have few predators when healthy and rare cases of predation by ablack kite[36] and ajungle crow may be of sick or injured birds.[37] An individual found dead with its beak embedded into the wood of a tree has been suggested as an accident during rapid pursuit of prey, possibly anIndian white-eye.[33] A few parasites have been noted.[38]
In the 1800s these birds were hunted for their bright feathers that were used to adorn hats.[39]
