Rare
Under 5% of wildlife watchers report a Chinese Blue Flycatcher sighting in Cuc Phuong National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 150th most-seen of the 159 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
March
In that month about 10% of wildlife watchers report a Chinese Blue Flycatcher in Cuc Phuong National Park on a given day, against under 5% in April–June and August–February, the lowest months. That is one of Cuc Phuong National Park's driest months, with about 80 mm of rain against 390 mm in August. July has too few records to rate.
5th of 6
Of the 6 parks where we can rate Chinese Blue Flycatcher sightings, Cuc Phuong National Park ranks 5th at under 5%. The best odds are in Kaeng Krachan National Park (Thailand, about 10%), Khao Luang National Park (Thailand, about 10%) and Khao Sok National Park (Thailand, about 10%).
Same genus: Cyornis
The closest relatives of the Chinese Blue Flycatcher that you can see in Cuc Phuong National Park (genus Cyornis, Blue Flycatchers and Jungle Flycatchers) are White-Tailed Blue-Flycatcher (about 10%) and Hainan Blue-Flycatcher (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chinese Blue Flycatcher is recorded against all the birds logged in Cuc Phuong National Park (5 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.
