Field Marks and
Identifying Characteristics:
Tiny wren with very short tail, consistently held upright. Dark, ochre-brown back half (tail, wings, flanks) with lighter brown head and breast – colder tones overall. Less warm/buffy coloration than expected for Pacific Wren.

Audibles used to confirm ID. Giving song-sparrow like calls and two other call types from dense vegetation; very skulky, fast-moving, and generally staying low to the ground.
(see photos)
Song or call & method of delivery: 3 call-types heard, all of which sounded “off” for a Pacific. See Video – this call type was used most frequently and reminded me of a particular chip done by Song Sparrows. “Jeet” calls, huskier and more nasal than Pacific Wren.
Behavior: Very skulky, fast-moving, generally staying low to the ground.
Habitat: Dense foliage and brush near flowing stream.
Similar species and how
were they eliminated:
House Wren: Darker brown and less uniform in overall coloration; much shorter tailed. Distinctive audibles ruled out House Wren.

Pacific Wren: Lack of warm/buffy-brown coloration. Vocalizations were the most determining factor in ID.
Previous experience with
this & similar species:
Have encountered Winter Wren >5 times total, the most recent prior to this sighting, being in November of 2020. Much more experience with Pacific Wren across the west coast.
