The Pacific wren (Troglodytes pacificus) is a very small North American bird and a member of the mainly New World wren family Troglodytidae. The species was formerly lumped together with either the winter wren (Troglodytes hiemalis) of eastern North America alone, or also with the Eurasian wren (Troglodytes troglodytes) of Eurasia, then under the merged name of northern wren with the scientific name T. troglodytes having priority.
It breeds along the Pacific coast from Alaska to California and inland as far as Wyoming and the Black Hills of South Dakota. It migrates through and winters across the western half of the United States and Canada. The scientific name is taken from the Greek word troglodytes (from trogle a hole, and dyein to creep), meaning 'cave-dweller', and refers to its habit of disappearing into cavities or crevices whilst hunting arthropods or to roost.
Rufous brown above, richly colored below, barred with darker brown and dusky, even on wings and tail. The bill is dark brown, the legs pale brown. Young birds are less distinctly barred.

Rare
Under 5% of wildlife watchers report a Pacific Wren sighting in Los Angeles on a given day, based on 76 verified sightings from GBIF citizen-science data. It is the 348th most-seen of the 426 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 Pacific Wren in Los Angeles on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Pacific Wren sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 7
Of the 7 cities where we can rate Pacific Wren sightings, Los Angeles ranks 7th at under 5%. The best odds are in Vancouver (Canada, about 20%), Seattle (United States, about 20%) and Portland (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Pacific Wren is recorded against all the birds logged in Los Angeles (76 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.
