Description of the Bird

What got my attention was a strong repeated chip note. The bird was very skulky, giving only brief partial looks. It then stopped calling, and I did not see it again for several minutes. Then it started calling again, and came out briefly onto the willow branches for some better looks, and I was able to get a few photos. Then it disappeared into the grasses again.

Similar Species Discussion

I thought this might be a Marsh Wren, given the rich colors. However, this bird had a streaked crown, strongly barred shoulders and wings, a short tail, and very buffy flanks, which fit much better for a Sedge Wren.

Resources Used

I verified it at home using the Cornell website (, Merlin photo ID app, and by submitting it to the ABA (What's This Bird?) site for verification.

Previous Experience

This is the first Sedge Wren I have seen. In the past, I have seen many House Wrens, quite a few Marsh Wrens, a Pacific Wren and a Winter Wren.
