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...

With luck
About 10% of wildlife watchers report a Black-naped Monarch sighting in Jim Corbett National Park on a given day, based on 169 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 183rd most-seen of the 368 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Black-naped Monarch in Jim Corbett National Park on a given day, against under 5% in August and November–April, the lowest months. That is one of Jim Corbett National Park's wettest months, with about 160 mm of rain against almost none in November.
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.
29th of 41
Of the 41 parks where we can rate Black-naped Monarch sightings, Jim Corbett National Park ranks 29th at about 10%. 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 Jim Corbett National Park (169 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.
