Virginia's Warbler (Leiothlypis virginiae) (1)
- Reported Sep 12, 2025 14:05 by Nick & Jane
- Meadow Park--San Luis Obispo, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.6606531&<ll...>,-120.6606531
- Checklist: https://ebird.org/checklist/S273002761
- Comments: "Continuing first-year, light-grey warbler with yellow undertail coverts and no tail. When I arrived to the Casa Diablo area in the southeastern area of the park, I joined some birders already in the location. No sooner than I walked up, the bird flew out of the northwest, at a downward angle to the upper portion of a bottlebrush tree, where the bird immediately began calling. Its chip was short and rising, similar to a Nashville, slightly more emphatic, and it called several times. We could see the plump grey warbler atop the right side of the tree from where we were facing north. The warbler was a bit hidden at times, occasionally revealing its size, shape and greyness. It then popped out and flew southeastward into a tree. Didn’t note any yellow on breast, and didn’t see its head well enough for an eyering glimpse. It was kind of cute without its tail, like a feathery little balloon with wings. Seen by around five people. No photo."
