Field Marks and
Identifying Characteristics:
Classic stub-tailed wren: small, dark wren with very short tail cocked upward. Dark brown above with paler grayish-brown underparts, pale supercilium, and barring on flanks and tail.
 
Song or call & method of delivery:

First heard single distant "chimp" note and immediately thought WIWR but there were at least a dozen SOSP in the vicinity so I was hesitant to call it. Started pishing and the bird moved in instantly, giving distinctive doubled "chimp chimp" calls.
(audio)

Behavior: Foraging very low to the ground (never more than one or two feet off the ground) in dense tangles. Moving very frenetically, flicking wings often.
Habitat: Dense dry deciduous vegetation stacked up against base of russian olive thickets. South side of Bountiful Lake along the canal.
Similar species and how
were they eliminated:
Chimp calls lower and rougher than PAWR with SOSP-like quality (not high, short "chet" of PAWR). Lower on spectrogram than PAWR as well (loudest part of call around 4 kHz vs. 6-7) with distinct harmonic bands. Plumage rather pale gray-brown and heavily patterned unlike the darker rufous-brown of PAWR (but calls are what ultimately cinched the ID). Vaguely similar in appearance to HOWR but smaller, darker, shorter tail, and heavier barring on flanks. Call also much different from HOWR.
Previous experience with
this & similar species:
Extensive experience with this species from New Hampshire. Have also recorded it several times in Wyoming and Colorado. Some experience with Pacific Wren from Oregon, California, and Colorado.
