The Baikal teal (Sibirionetta formosa), also called the bimaculate duck or squawk duck, is a dabbling duck that breeds in eastern Russia and winters in East Asia. The first formal description of the Baikal teal was by the German naturalist Johann Gottlieb Georgi in 1775 under the binomial name Anas formosa. A molecular phylogentic study published in 2009 found that the genus Anas as then defined was non-monophyletic. Based on this analysis the genus was split into four proposed genera with the Baikal teal placed in the resurrected genus Sibirionetta that had been introduced by the German zoologist Hans von Boetticher in 1929. The name Sibirionetta is derived from the Latin sibiricus for Siberia and the Ancient Greek nētta for a duck. The specific epithet formosa is from the Latin formosus for "beautiful".
The Baikal teal has a height of 30–40 cm (11.75–15.75 in), and a weighs an average of 500 g (1 lb). At a length between 39–43 cm (15–17 in), this duck is slightly larger and longer-tailed than the common teal. The breeding male is unmistakable, with a striking green nape, yellow and black auriculars, neck, and throat. It has a dark crown, and its breast... Wikipedia →

Rare
Under 5% of wildlife watchers report a Baikal Teal sighting in Beijing on a given day, based on 226 verified sightings from GBIF citizen-science data. It is the 133rd most-seen of the 324 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January to March
In those months about 10% of wildlife watchers report a Baikal Teal in Beijing on a given day, against under 5% in April to December, the lowest months. Those are among Beijing's driest months, with about 5 mm of rain a month against 150 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Baikal Teal sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 9 cities where we can rate Baikal Teal sightings, Beijing has the highest daily chance: under 5%. Next come Fukuoka (Japan, under 5%) and Seoul (South Korea, under 5%).
Same family: Anatidae
The closest relatives of the Baikal Teal that you can see in Beijing (family Anatidae, Ducks, Geese, and Swans) are Mallard (about 70%), Mandarin Duck (about 30%) and Ruddy Shelduck (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Baikal Teal is recorded against all the birds logged in Beijing (226 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.
