The scaly-sided merganser or Chinese merganser (Mergus squamatus) is an endangered typical merganser (genus Mergus). It lives in Manchuria and extreme Southeast Siberia, breeding in the north and wintering in the south. This striking sea duck has a thin red bill and a scaled dark pattern on the flanks and rump. Both sexes have a crest of wispy elongated feathers, reaching almost to the shoulders in adult males and being fairly short in females and immatures. The adult male has a black head and neck, white breast and underparts, and blackish mantle and wings, except for the white innerwings. The scaling is also black, while the tail is medium grey. The female has a buffish head and otherwise replaces the male's black with grey colour. The legs are orange-red and the irides dark brown in both sexes.
Their breeding habitat is rivers in primary forest in the southeastern Russian Far East, perhaps in North Korea, and in two locations Changbai Mountains and small isolated location in Lesser Xingan Mtns. in northeastern China. The bulk of the species' population breed in Russian Far East (85%) and Changbaishan both in China and DPRK M. squamatus are migratory... Wikipedia →

Rare
Under 5% of wildlife watchers report a Scaly-sided Merganser sighting in Beijing on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 318th most-seen of the 324 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Scaly-sided Merganser in Beijing on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Scaly-sided Merganser sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Beijing, in our data
Beijing is the only city on Wallace's Line with enough records to rate Scaly-sided Merganser sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Scaly-sided Merganser is recorded against all the birds logged in Beijing (5 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.
