The golden-crowned kinglet (Regulus satrapa) is a very small songbird in the family Regulidae that lives throughout much of North America. Adults are olive-gray on the upperparts with white underparts, thin bills and short tails. They have white wing bars, a black stripe through the eyes and a yellow crown surrounded by black. The adult male has an orange patch in the middle of the yellow crown. The juvenile is similar to the adult, but with a browner back and without the yellow crown. This is one of the smallest passerines in North America. Its length, at 8 to 11 cm (3.1 to 4.3 in), is probably the shortest of any American passerine. Its weight, averaging 6.1 g (0.22 oz) for females and 6.3 g (0.22 oz) for males and ranging from 4.5 to 7.8 g (0.16 to 0.28 oz), is similar to the American bushtit and black-tailed gnatcatcher. The golden-crowned kinglet has a wingspan of 5.5–7.1 in (14–18 cm).
The golden-crowned kinglet is insectivorous, foraging in trees or shrubs, where it eats insects (especially caterpillars), insect eggs and spiders. It produces a series of high-pitched calls on a single note, and tends not to fear human approach. Its nest is a well... Wikipedia →

Rare
Under 5% of wildlife watchers report a Golden-crowned Kinglet sighting in San Francisco on a given day, based on 1,655 verified sightings from GBIF citizen-science data. It is the 179th most-seen of the 375 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
November and December
In those months about 10% of wildlife watchers report a Golden-crowned Kinglet in San Francisco on a given day, against under 5% in January to October, the lowest months. Those are among San Francisco's wettest months, with about 85 mm of rain a month against almost none in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Golden-crowned Kinglet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
20th of 27
Of the 27 cities where we can rate Golden-crowned Kinglet sightings, San Francisco ranks 20th at under 5%. The best odds are in Seattle (United States, about 40%), Vancouver (Canada, about 30%) and Portland (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Golden-crowned Kinglet is recorded against all the birds logged in San Francisco (1,655 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.
