Its natural habitat is evergreen and secondary forests. Threatened by habitat loss, it has been assessed as a near-threatened species.
Salomon Müller described the species in 1845, as Cuculus vagans. The species is monotypic. The moustached hawk-cuckoo is found in southern Myanmar, Thailand, southern Laos, Malaysia, Singapore, Brunei, and Kalimantan, Sumatra and Java of Indonesia. Its habitat is evergreen and secondary forests and forest edges, especially on hills and in alluvial and bamboo forests. It occurs at elevations up to 915 m (3,002 ft).
The moustached hawk-cuckoo is 25–30 cm (9.8–11.8 in) long, and it weighs about 58–63 g (2.0–2.2 oz). The crown and nape are grey. The ear coverts are white, and there is a blackish moustache.

Rare
Under 5% of wildlife watchers report a Moustached Hawk-Cuckoo sighting in Kinabalu Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 202nd most-seen of the 247 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Moustached Hawk-Cuckoo in Kinabalu Park on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Moustached Hawk-Cuckoo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 parks where we can rate Moustached Hawk-Cuckoo sightings, Kinabalu Park ranks 5th at under 5%. The best odds are in Danum Valley Conservation Area (Malaysia, about 10%), Taman Negara National Park (Malaysia, under 5%) and Kinabatangan Wildlife Sanctuary (Malaysia, under 5%).
Same genus: Cuculus
The closest relatives of the Moustached Hawk-Cuckoo that you can see in Kinabalu Park (genus Cuculus, Typical Old World Cuckoos) are Sunda Cuckoo (about 20%) and Large Hawk Cuckoo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Moustached Hawk-Cuckoo is recorded against all the birds logged in Kinabalu Park (12 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.
