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.
Today was one of those “just when I think I have this figured out” days.
As I was rounding the west perimeter of the Noble Research Center between the southwest and northwest alcoves, some feathers caught my eye up against the brick side of the building. This is the first time (in nearly 8 years) I found a bird at this spot and it was also pretty clearly one new to the study: a bright orange and black Baltimore Oriole, or at least a nice pile of feather remnants from what had lately been an adult male (ASY) Baltimore Oriole.
Though for consistency’s sake I’ll record that spot on the building as the location of collision, I in fact don’t know where the bird hit. All I know is that a predator (and very likely a cat based on the neatly sheared primaries) appears to have eaten said oriole at that spot.
Confirming Baltimore Oriole as the source of the wing.
Around the corner and into the northwest alcove, I found the remnants of a scavenged adult Mourning Dove. Here again was a bird in a very odd location. Strangely enough, the bird was in the exact location (beneath an ornamental buttonbush) where collaborator and OSU PhD student Corey Riding had the week before left a Cedar Waxwing carcass for a scavenging trial. Corey, however, had left neither a dove, an oriole, nor anything else at that spot since the waxwing. Puzzling for sure . . .
Finally, there was another bird at the end of the alcove in front of one of the untreated panes. Here was another oddity – a House Wren.
