Rare
Under 5% of wildlife watchers report a Hainan Blue-Flycatcher sighting in Guangzhou on a given day, based on 115 verified sightings from GBIF citizen-science data. It is the 96th most-seen of the 266 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April–June and August–September
In those months about 10% of wildlife watchers report a Hainan Blue-Flycatcher in Guangzhou on a given day, against under 5% in July and October–March, the lowest months. Those are among Guangzhou's wettest months, with about 230 mm of rain a month against 30 mm in December.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Hainan Blue-Flycatcher sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 5 cities where we can rate Hainan Blue-Flycatcher sightings, Guangzhou has the highest daily chance: under 5%. Next come Hanoi (Vietnam, under 5%) and Hong Kong (China, under 5%).
Same family: Muscicapidae
The closest relatives of the Hainan Blue-Flycatcher that you can see in Guangzhou (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Oriental Magpie-Robin (about 80%), Daurian Redstart (about 10%) and Amur Stonechat (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hainan Blue-Flycatcher is recorded against all the birds logged in Guangzhou (115 verified sightings), 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.
