I really think I have an Orange-Crowned Warbler in my yard, and wonder if anyone else has seen one. It really does not seem possible, given the time of year, but the description matches (olive in color overall, thin pale eye arc, bright yellow undertail coverlet - all confirmed). I noticed it feeding on some bark butter, along with Juncos and White-Throated Sparrows.
And before anyone suggests: it is definitely not a Goldfinch or a Kinglet. It is the shape and size of a Warbler, and also has the behavior and movements of one. It is also not any other Warbler one might happen to see this time of year, such as a Yellow-Rumped.
