The rufous-tailed robin (Larvivora sibilans) is a small passerine bird. Its breeding range extends from southern Siberia and the Sea of Okhotsk to southern China and southeastern Asia. It has a number of alternative English names: pseudorobin, red-tailed robin, Swinhoe's red-tailed robin, Swinhoe's robin, Swinhoe's pseudorobin, Swinhoe's nightingale or whistling nightingale.
The rufous-tailed robin was previously placed in the genus Luscinia. A large molecular phylogenetic study published in 2010 found that Luscinia was not monophyletic. The genus was therefore split and several species including rufous-tailed robin were moved to the reinstated genus Larvivora. The rufous-tailed robin is genetically most closely related to the rufous-headed robin (Larvivora ruficeps). These two species form a sister group to a clade containing the Japanese robin (Larvivora akahige) and the Ryukyu robin (Larvivora komadori).
The genus name Larvivora comes from the Neo-Latin larva meaning caterpillar and -vorus meaning eating (vorace to devour), and sibilans is Latin for "whistling". The rufous-tailed robin is much the same size as the European robin at 14 cm (5.5 in... Wikipedia →

Rare
Under 5% of wildlife watchers report a Rufous-tailed Robin sighting in Guangzhou on a given day, based on 103 verified sightings from GBIF citizen-science data. It is the 101st 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.
December to March
In those months about 10% of wildlife watchers report a Rufous-tailed Robin in Guangzhou on a given day, against under 5% in April to November, the lowest months. Those are among Guangzhou's driest months, with about 50 mm of rain a month against 330 mm in June.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Rufous-tailed Robin 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.
5th of 13
Of the 13 cities where we can rate Rufous-tailed Robin sightings, Guangzhou ranks 5th at under 5%. The best odds are in Jinhua (China, about 20%), Zhuhai [Macau] (China, about 10%) and Hong Kong (China, about 10%).
Same family: Muscicapidae
The closest relatives of the Rufous-tailed Robin 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 Rufous-tailed Robin is recorded against all the birds logged in Guangzhou (103 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.
