With luck
About 10% of wildlife watchers report a Chinese Blue Flycatcher sighting in Khao Sok National Park on a given day, based on 54 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 111th most-seen of the 213 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

Of the 6 parks where we can rate Chinese Blue Flycatcher sightings, Khao Sok National Park ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Kaeng Krachan National Park (Thailand, about 10%) and Khao Luang National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Chinese Blue Flycatcher is recorded against all the birds logged in Khao Sok National Park (54 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.
