Field Marks and
Identifying Characteristics:

First heard the Wren, noted calls seemed different than the Pacific Wren I had heard and seen a few minutes earlier,less scratchy more of a chump than a chimp. played the Winter Wren call on my iBird Pro app to compare and bring the bird in for a better look, noted very small rusty brown wren with a short tail, but noticed throat was rather pale with some whitish mottling, unlike the very rusty throat of the Pacific Wren I had just had excellent looks at.I immediately got a recording of the wren, and upon uploading and comparing the graph with other recordings on Macualay Library, confirmed what I suspected in the field that this was indeed a Winter Wren. I also managed a few poor photos

Song or call & method of delivery: Heard giving distinctive chump calls and excited trill call, Chump call recorded.
Behavior: Wren was very sulky, originally in thickets near the creek, but came in closer and even crossed the road, but always stayed low and in heavy cover.
Habitat: Riparian canyon bottom
Similar species and how
were they eliminated:
Pacific Wren is very similar, and indeed they were considered the same species until just a few years ago,but Pacific has a scratchier, higher and thinner call. Also typically they have a very rufous throat and breast. This Wren had a pale throat with some whitish mottling.
Previous experience with
this & similar species:
I've seen and heard many Pacific Wrens. This is my first time confirming a Winter Wren with a recording, although I've had a few suspects over the past couple years.
