With luck
About 10% of wildlife watchers report a Hutton's Vireo sighting in San Francisco on a given day, based on 5,114 verified sightings from GBIF citizen-science data. It is the 123rd 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 30%, if each day is a fresh chance.
April–June and August–October
In those months about 10% of wildlife watchers report a Hutton's Vireo in San Francisco on a given day, against under 5% in July and November–March, the lowest months. Those are among San Francisco's driest months, with about 15 mm of rain a month against 110 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Hutton's Vireo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 16 cities where we can rate Hutton's Vireo sightings, San Francisco ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Toluca (México, about 10%) and Los Angeles (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Hutton's Vireo is recorded against all the birds logged in San Francisco (5,114 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.
