The marbled murrelet (Brachyramphus marmoratus) is a small seabird from the North Pacific. It is a member of the family Alcidae, which includes auklets, guillemots, murres and puffins. It nests in old-growth forests or on the ground at higher latitudes where trees cannot grow. Its population has declined since humans began logging its nest trees in the latter half of the 19th century. The decline of the marbled murrelet and its association with old-growth forests—at least in the southern part of its range—have made it a flagship species in the forest protection movement.
The marbled murrelet 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 grebes and loons in the genus Colymbus and coined the binomial name Colymbus marmoratus. Gmelin based his description on the "marbled murrelet" that had been described and illustrated in 1785 by both the English ornithologist John Latham and by the Welsh naturalist Thomas Pennant. Both authors mention the two specimens in the Leverian Museum that had been collected in Prince William Sound during James Cook's third... Wikipedia →

Rare
Under 5% of wildlife watchers report a Marbled Murrelet sighting in San Francisco on a given day, based on 77 verified sightings from GBIF citizen-science data. It is the 293rd most-seen of the 375 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 Marbled Murrelet in San Francisco 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 Marbled Murrelet sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate Marbled Murrelet sightings, San Francisco ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Seattle (United States, under 5%) and Vancouver (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Marbled Murrelet is recorded against all the birds logged in San Francisco (77 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.
