The grey-headed canary-flycatcher (Culicicapa ceylonensis), sometimes known as the grey-headed flycatcher, is a species of small flycatcher-like bird found in tropical Asia. It has a square crest, a grey hood and yellow underparts. They are found mainly in forested habitats where they often join other birds in mixed-species foraging flocks. Pairs are often seen as they forage for insects by making flycatcher-like sallies and calling aloud. Several subspecies are recognized within their wide distribution range. In the past the genus Culicicapa was considered to be an Old World flycatcher but studies have found them to belong to a new family designated as the Stenostiridae or fairy flycatchers that include the African genera Stenostira and Elminia.
The grey-headed canary-flycatcher is about 12–13 cm (4.7–5.1 in) long with a squarish grey head, a canary yellow belly and yellowish-green upperparts. They forage actively like flycatchers and perches in a very upright posture. The sexes are indistinguishable in plumage. They have a very flat bill (which gave it the earlier genus name of Platyrhynchus) which when seen from above look like an equilateral triangle and is fringed... Wikipedia →
Rare
Under 5% of wildlife watchers report a Grey-headed Canary-Flycatcher sighting in Beijing on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 119th most-seen of the 324 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.
September
In that month about 10% of wildlife watchers report a Grey-headed Canary-Flycatcher in Beijing on a given day, against under 5% in October to August, the lowest months. That is one of Beijing's wettest months, with about 65 mm of rain against almost none in January.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Grey-headed Canary-Flycatcher sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
22nd of 35
Of the 35 cities where we can rate Grey-headed Canary-Flycatcher sightings, Beijing ranks 22nd at under 5%. The best odds are in Kathmandu (Nepal, about 20%), Dehradun (India, about 20%) and Jabalpur (India, about 20%).
Same order: Passeriformes
The closest relatives of the Grey-headed Canary-Flycatcher that you can see in Beijing (order Passeriformes, Perching Birds) are Oriental Magpie (about 90%), Azure-winged Magpie (about 90%) and Eurasian Tree Sparrow (about 90%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Grey-headed Canary-Flycatcher is recorded against all the birds logged in Beijing (5 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.
