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 Hangzhou on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 155th most-seen of the 219 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.
April
In that month about 10% of wildlife watchers report an Asian Stubtail in Hangzhou on a given day, against under 5% in May to March, the lowest months.
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.
7th of 12
Of the 12 cities where we can rate Asian Stubtail sightings, Hangzhou ranks 7th at under 5%. The best odds are in Sendai (Japan, about 10%), Sapporo (Japan, about 10%) and Busan (South Korea, about 10%).
Same family: Cettiidae
The closest relatives of the Asian Stubtail that you can see in Hangzhou (family Cettiidae, Bush Warblers and Allies) are Brownish-flanked Bush-Warbler (about 40%) and Rufous-faced Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Asian Stubtail is recorded against all the birds logged in Hangzhou (21 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.
