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 tree kingfishers is resident over much of its range, but northern populations are migratory, wintering south of their range in Sri Lanka, Thailand, Borneo and Java. It is distinctive in having a black cap that contrasts with the whitish throat, purple-blue wings and the coral red bill. The species is mainly found in coastal and mangrove habitats but can sometimes be found far inland.
The black-capped kingfisher was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1780. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle, which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name, but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Alcedo pileata in his catalogue of the Planches Enluminées.

Rare
Under 5% of wildlife watchers report a Black-capped Kingfisher sighting in Thiruvananthapuram on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 139th most-seen of the 174 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-capped Kingfisher in Thiruvananthapuram on a given day, so our monthly data shows no clear season.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Black-capped Kingfisher sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
6th of 13
Of the 13 cities where we can rate Black-capped Kingfisher sightings, Thiruvananthapuram ranks 6th at under 5%. The best odds are in Bangkok (Thailand, about 10%), Yangon (Myanmar, under 5%) and Kozhikode (India, under 5%).
GBIF citizen-science records
It is estimated from how often the Black-capped Kingfisher is recorded against all the birds logged in Thiruvananthapuram (14 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
