The dark-sided flycatcher (Muscicapa sibirica) is a small passerine bird belonging to the genus Muscicapa in the Old World flycatcher family Muscicapidae. It has a wide breeding distribution in the East Palearctic with northern birds migrating south for the winter. It is also known as the Siberian flycatcher or sooty flycatcher, the latter name is also used for the sooty flycatcher (Artomyias infuscata) of Africa.
The dark-sided flycatcher was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the flycatchers in the genus Muscicapa and coined the binomial name Muscicapa sibirica. Gmelin based his account on the "Dunn flycatcher" that had been described in 1783 by the English ornithologist John Latham in his multi-volume work A General Synopsis of Birds. Latham reported that the bird was found around Lake Baikal in southern Siberia.

Rare
Under 5% of wildlife watchers report a Dark-sided Flycatcher sighting in San Francisco on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 150th most-seen of the 375 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.
September
In that month about 10% of wildlife watchers report a Dark-sided Flycatcher in San Francisco on a given day, against under 5% in October to August, the lowest months. That is one of San Francisco's driest months, with almost no rain against 110 mm in December.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Dark-sided Flycatcher sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
7th of 23
Of the 23 cities where we can rate Dark-sided Flycatcher sightings, San Francisco ranks 7th at under 5%. The best odds are in Qingdao (China, about 10%), Hanoi (Vietnam, about 10%) and Wuhan (China, about 10%).
Same order: Passeriformes
The closest relatives of the Dark-sided Flycatcher that you can see in San Francisco (order Passeriformes, Perching Birds) are American Crow (about 80%), House Finch (about 70%) and Black Phoebe (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dark-sided Flycatcher is recorded against all the birds logged in San Francisco (39 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.
