I found just the second-ever Baltimore Oriole on the project today, at the main north entrance. This was a SY female (fat = 2, 33.5 g) showing extreme feather wear and asymmetrical flight feather molt. See especially the difference in the 2nd tertiary (S8, if you prefer) between the left and right wings.
Note – a dull-plumaged female Baltimore Oriole can be difficult to distinguish from Bullock’s Oriole. This bird was easy to discern as Baltimore owing to brightest yellow in the center of the upper breast/throat (instead of higher on the cheek/malar), more brownish rather than grayish upperparts, and dark centers to brownish feather of the scapulars.
