Rare
Under 5% of wildlife watchers report a Rufous-bellied Swallow sighting in Taman Negara National Park on a given day, based on 51 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 175th most-seen of the 293 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and August
In those months about 10% of wildlife watchers report a Rufous-bellied Swallow in Taman Negara National Park on a given day, against under 5% in May–July and September–March, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Rufous-bellied Swallow sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Rufous-bellied Swallow sightings, Taman Negara National Park ranks 3rd at under 5%. The best odds are in Khao Sok National Park (Thailand, about 10%) and Khao Luang National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Rufous-bellied Swallow is recorded against all the birds logged in Taman Negara National Park (51 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.
