Just after noon today, Friday 11/18/22, I found a White-throated Sparrow by itself right at the entrance to the parking lot for the Old Mission Dam at Mission Trails. I don't know if this is the same one that was found father north in the park a couple days ago.
At Kumeyaay/Hollis Lakes I saw the American Bittern around 9am or so. I didn't find the Philadelphia Vireo, but apparently others did.
