The black-naped monarch (Hypothymis azurea) is a passerine bird belonging to the family of monarch flycatchers found in southern and south-eastern Asia. They are sexually dimorphic, with the male having a distinctive black patch on the back of the head and a narrow black half collar ("necklace"), while the female is duller with olive brown wings and lacking the black markings on the head. They have a call that is similar to that of the Asian paradise flycatcher, and in tropical forest habitats, pairs may join mixed-species foraging flocks. Populations differ slightly in plumage colour and sizes.
The black-naped monarch was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1779 in his Histoire Naturelle des Oiseaux. 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 Muscicapa azurea in his catalogue of the Planches...

Possible
About 30% of wildlife watchers report a Black-naped Monarch sighting in Danum Valley Conservation Area on a given day, based on 414 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 258 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
September
In that month about 50% of wildlife watchers report a Black-naped Monarch in Danum Valley Conservation Area on a given day, against about 10% in February and November, the lowest months.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Black-naped Monarch sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
12th of 41
Of the 41 parks where we can rate Black-naped Monarch sightings, Danum Valley Conservation Area ranks 12th at about 30%. The best odds are in Kaeng Krachan National Park (Thailand, about 60%), Khao Luang National Park (Thailand, about 50%) and Kanha National Park (India, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Black-naped Monarch is recorded against all the birds logged in Danum Valley Conservation Area (414 verified sightings from 2019 to 2026), 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.
