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 →
With luck
About 10% of wildlife watchers report a Grey-headed Canary-Flycatcher sighting in Hanoi on a given day, based on 35 verified sightings from GBIF citizen-science data. It is the 41st most-seen of the 97 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January
In that month about 30% of wildlife watchers report a Grey-headed Canary-Flycatcher in Hanoi on a given day, against under 5% in May and September, the lowest months. That is one of Hanoi's driest months, with about 30 mm of rain against 320 mm in August.
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.
5th of 35
Of the 35 cities where we can rate Grey-headed Canary-Flycatcher sightings, Hanoi ranks 5th at about 10%. 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 Hanoi (order Passeriformes, Perching Birds) are Swinhoe’s White-eye (about 90%), Eurasian Tree Sparrow (about 80%) and Common Tailorbird (about 80%), 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 Hanoi (35 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.
