The taiga bean goose (Anser fabalis) is a species of goose that breeds in northern Europe and Asia. It is migratory and winters further south in Europe and Asia. This and the tundra bean goose were recognised as separate species by the International Ornithologists' Union and the American Ornithological Society from 2007, but are still considered a single species by some other authorities (collectively called bean goose), notably BirdLife International and the IUCN. The taiga and tundra bean goose diverged about 2.5 million years ago and established secondary contact c. 60,000 years ago, resulting in extensive gene flow.
The length ranges from 68 to 90 cm (27–35 in), wingspan from 140 to 174 cm (55–69 in) and weight from 1.7–4 kg (3.7–8.8 lb). In the nominate subspecies, males average 3.2 kg (7.1 lb) and females average 2.84 kg (6.3 lb). The bill is black at the base and tip, with an orange band across the middle; the legs and feet are also bright orange.
The upper wing-coverts are dark brown, as in the white-fronted goose (Anser albifrons) and the lesser white-fronted goose (A. erythropus), but differing from these in having narrow white fringes to the feathers. The... Wikipedia →

Rare
Under 5% of wildlife watchers report a Taiga Bean Goose sighting in Moscow on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 148th most-seen of the 171 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 Taiga Bean Goose in Moscow on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Taiga Bean Goose sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 9
Of the 9 cities where we can rate Taiga Bean Goose sightings, Moscow ranks 8th at under 5%. The best odds are in Novosibirsk (Russia, about 10%), Seoul (South Korea, under 5%) and Helsinki (Finland, under 5%).
GBIF citizen-science records
It is estimated from how often the Taiga Bean Goose is recorded against all the birds logged in Moscow (13 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.
