Field Marks and
Identifying Characteristics:
I never viewed the bird.
Song or call & method of delivery: Gave wit-weet call continuously for about 5 minutes with anywhere from 10-30 seconds between calls. Was hidden in a shrub the entire time. Spectrogram comparisons between the call note of my bird and other Curve-billed Thrashers in nearly identical, but individual birds can have slight variations to their calls notes.
Behavior: I never got a look at the thrasher. It was calling in a shrub in an adjacent yard to the hotel. It gave the distinctive wit-weet of western Curve-billed Thrasher.
Habitat: Residential area with large open yards and various large shrubs and trees.
Similar species and how
were they eliminated:
No other species gives a call like the wit-weet of the western Curve-billed Thrasher.

Mockingbirds could possibly mimic the call but the call was never quickly repeated and there were no interspersed calls like would be expected with a mockingbird, just the wit-weet.
Previous experience with
this & similar species:
I have seen and heard dozens in Arizona.
