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 Kenai Fjords National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 99 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
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.
10th of 13
Of the 13 parks where we can rate Pacific Wren sightings, Kenai Fjords National Park ranks 10th at under 5%. The best odds are in Pacific Rim National Park Reserve (Canada, about 60%), Redwood National Park (United States, about 60%) and Olympic National Park (United States, about 40%). All parks ranked.
Same order: Passeriformes
The closest relatives of the Pacific Wren that you can see in Kenai Fjords National Park (order Passeriformes, Perching Birds) are Hermit Thrush (about 40%), Orange-crowned Warbler (about 30%) and Wilson's Warbler (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pacific Wren is recorded against all the birds logged in Kenai Fjords National Park (27 verified sightings from 2019 to 2026), 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.
