We want to thank Nancy Overholtz for finding and Curtis Marantz for later identifying this bird - the first we have seen in Inyo and the third record ever. This bird was originally found by Nancy and Diane Stevens on 13 Nov 2023 (https://ebird.org/checklist/S154410483) and later identified by Curtis when he looked at Nancy's photographs and listened to her recordings. We located it here (37.124555, -118.436189) in the dense birch tangles behind the green dumpster northeast of the foundation of the former Glacier Lodge. General directions: cross the bridge and turn left - you'll see the green dumpster on your left. We drove up from Bishop to attempt to refind this bird and had walked all of the campground and were about to give up when we heard it call its distinctive low-pitched call notes from the dense tangles behind the dumpster. We were able to obtain several audio recordings (all confirmed as Winter Wren by Merlin), photos, and videos. The bird was paler than the Pacific Wren we had just seen 25 minutes earlier, particularly in the throat and breast. (Merlin correctly identified the Pacific as a Pacific.) The Pacific Wren was a rich reddish brown from throat to belly, whereas the Winter was off-white in the throat warming slightly in the belly. The flanks were much grayer in tone, lacking reddish brown hues altogether. The extremely short, cocked tail was the most richly colored part of the bird, both above and below, a rich reddish brown with dark barring. Because lighting can be so difficult and changeable with low-angle, late-season mountain light we found the best way for us to distinguish between the two birds was by the way they sound. The call notes of the Winter Wren were lower in pitch and strikingly different from Pacific, which was much higher in pitch and sharper. The Winter Wren call note resembled the low pitch and hoarse quality of Song Sparrow. The sonogram resulting from the audio recordings of the Winter Wren showed some harmonics and were most dense in the lower frequencies. We also studied the sonograms of Pacific Wren, both from what we obtained in the field and what were available on the web.
