Townsend's Warblers may be masked but they're not bandits.
A Catharus species showed up on the 24th, but I was unable to get a positive ID on it. With much going back and forth by experts, it is now officially an "Olive-backed" Swainson's Thrush. Whew! Sometimes it takes a village. CMO is either thrush heaven or thrush hell, not sure which. Kidding!
