The red-throated thrush (Turdus ruficollis) is a passerine bird in the thrush family. It is sometimes regarded as one subspecies of a polytypic species, "dark-throated thrush", black-throated thrush then being the other subspecies. More recent treatments regard the two as separate species. The scientific name comes from Latin. Turdus is "thrush" and the specific ruficollis is derived from rufus, "red", and collum, "neck".
The red-throated thrush is a migratory Palearctic species. It breeds in East Siberia to North Manchuria wintering to West China, Myanmar, and Northeast India. Its range overlaps with the more westerly-breeding black-throated thrush. It is a large thrush with a plain grey back and reddish underwings. The adult male has a red throat. Females and young birds lack the bib, but have black-streaked underparts. This bird species is a very rare vagrant to western Europe.

Rare
Under 5% of wildlife watchers report a Red-throated Thrush sighting in Hong Kong on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 70th most-seen of the 204 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.
November and December
In those months about 10% of wildlife watchers report a Red-throated Thrush in Hong Kong on a given day, against under 5% in January to October, the lowest months. Those are among Hong Kong's driest months, with about 30 mm of rain a month against 280 mm in June.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Red-throated Thrush sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 8
Of the 8 cities where we can rate Red-throated Thrush sightings, Hong Kong ranks 6th at under 5%. The best odds are in Xining (China, about 10%), Lanzhou (China, about 10%) and Beijing (China, about 10%).
Same genus: Turdus
The closest relatives of the Red-throated Thrush that you can see in Hong Kong (genus Turdus, Typical Thrushes) are Grey-backed Thrush (about 10%), Japanese Thrush (about 10%) and Chinese Blackbird (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-throated Thrush is recorded against all the birds logged in Hong Kong (8 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.
