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 →

Likely
About 40% of wildlife watchers report a Rufous-tailed Robin sighting in Cuc Phuong National Park on a given day, based on 127 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 159 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
February
In that month about 60% of wildlife watchers report a Rufous-tailed Robin in Cuc Phuong National Park on a given day, against about 10% in April and October, the lowest months. That is one of Cuc Phuong National Park's driest months, with about 50 mm of rain against 390 mm in August. July has too few records to rate.
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.
Only Cuc Phuong National Park, in our data
Cuc Phuong National Park is the only park on Wallace's Line with enough records to rate Rufous-tailed Robin sightings: about 40% of wildlife watchers there report one on a given day.
Same family: Muscicapidae
The closest relatives of the Rufous-tailed Robin that you can see in Cuc Phuong National Park (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are White-rumped Shama (about 40%), Fujian Niltava (about 30%) and White-tailed Robin (about 20%), 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 Cuc Phuong National Park (127 verified sightings from 2019 to 2026), 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.
