Several people who have experience with Winter Wren expressed that it sounds really good for a potential winter wren but more documentation would be great.
I stopped there yesterday evening to follow up and was not able to relocate it hearing only a typical Pacific Wren at the same spot. BUT, a visit at sunrise today turned up both a Pacific and the putative WINTER WREN at these approximate GPS coordinates : 37.74947, -122.4689
Do note that this is a state review species so if you go see the bird and manage photos/recordings please submit them to the California BIrd Record Committee at this link: https://californiabirds.org/report_sighting.html
