The wrentit (Chamaea fasciata) is a small bird that lives in chaparral, oak woodlands, and bushland on the western coast of North America, from Oregon south through California to northern Baja California. It is the only species in the genus Chamaea.
Its systematics have been the subject of much debate, the wrentit having been placed in many different families by different authors for as long as it has been known to science. Its common name reflects the uncertainty, and its external resemblance to both tits and wrens. It is not related to either, however. More recent and comprehensive phylogenetic studies support it belonging to the parrotbill family Paradoxornithidae.
The wrentit is a small, 14–16 cm (5.5–6.3 in) bird with uniform dull olive, brown, or grayish plumage. It has short wings and a long tail often held high (hence the comparison to wrens). It has a short bill and a pale iris. Given its retiring nature and loud voice, the wrentit is more likely to be detected by its call than by sight. The distinct sound that it makes is similar to the sound of a ping-pong ball falling on the table.

Rare
Under 5% of wildlife watchers report a Wrentit sighting in San Francisco on a given day, based on 1,217 verified sightings from GBIF citizen-science data. It is the 189th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Wrentit in San Francisco on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Wrentit sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 cities where we can rate Wrentit sightings, San Francisco ranks 3rd at under 5%. The best odds are in San Diego (United States, about 20%) and Los Angeles (United States, about 10%).
Same order: Passeriformes
The closest relatives of the Wrentit 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 Wrentit is recorded against all the birds logged in San Francisco (1,217 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.
