The Asian stubtail (Urosphena squameiceps) is a bird in the family Cettiidae. The species was first described by Robert Swinhoe in 1863. It breeds in Northeast Asia and Japan. Its natural habitat is temperate forest. It is a small bird with a short tail. Males and females are similar in color, as well as juveniles after fledging; they are brown all over with a paler underpart and a darker brown crest and eyeline.
Breeding Asian stubtails reside in portions of northeastern Asia; non-breeding areas include Hainan Taiwan, southeastern China and Indochina, preferring a habitat of undergrowth in evergreen broadleaf or lowland coniferous forest.
Breeding males produce a high-pitched shee-shee-shee-shee or cee-cee-cee, while both males and females make a call similar to chott-chott-chott. Wikipedia →

Rare
Under 5% of wildlife watchers report an Asian Stubtail sighting in Seoul on a given day, based on 61 verified sightings from GBIF citizen-science data. It is the 151st most-seen of the 231 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Asian Stubtail in Seoul on a given day, so our monthly data shows no clear season.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most Asian Stubtail sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
9th of 12
Of the 12 cities where we can rate Asian Stubtail sightings, Seoul ranks 9th at under 5%. The best odds are in Sendai (Japan, about 10%), Sapporo (Japan, about 10%) and Busan (South Korea, about 10%).
GBIF citizen-science records
It is estimated from how often the Asian Stubtail is recorded against all the birds logged in Seoul (61 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.
