Rare
Under 5% of wildlife watchers report a Moustached Hawk-Cuckoo sighting in Kaeng Krachan National Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 292nd most-seen of the 360 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 Moustached Hawk-Cuckoo in Kaeng Krachan National 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.
4th of 5
Of the 5 parks where we can rate Moustached Hawk-Cuckoo sightings, Kaeng Krachan National Park ranks 4th 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%).
GBIF citizen-science records
It is estimated from how often the Moustached Hawk-Cuckoo is recorded against all the birds logged in Kaeng Krachan National Park (26 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.
