The fork-tailed sunbird (Aethopyga christinae) is a bird in the family Nectariniidae. The species was first described by Robert Swinhoe in 1869. It is found in China, Hong Kong, Laos, and Vietnam. Its natural habitat is subtropical or tropical moist lowland forests. These small birds, with decurved bill, call a soft and frequent "zwink-zwink" and a metallic trill. The bird appears in the most commonly used postal stamp of Hong Kong. Wikipedia →

Possible
About 30% of wildlife watchers report a Fork-tailed Sunbird sighting in Hong Kong on a given day, based on 853 verified sightings from GBIF citizen-science data. It is the 18th most-seen of the 204 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
December
In that month about 60% of wildlife watchers report a Fork-tailed Sunbird in Hong Kong on a given day, against about 10% in June to October, the lowest months. That is one of Hong Kong's driest months, with about 25 mm of rain against 280 mm in June.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Fork-tailed Sunbird 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.
2nd of 13
Of the 13 cities where we can rate Fork-tailed Sunbird sightings, Hong Kong ranks 2nd at about 30%. The best odds are in Fuzhou (China, about 40%).
GBIF citizen-science records
It is estimated from how often the Fork-tailed Sunbird is recorded against all the birds logged in Hong Kong (853 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.
