Although American Robin is one of the most commonly reported window strike victims, this is only the second time I’ve had one at the Noble Research Center. I found this fledgling/local bird in the northwest alcove.
Though they might have come in yesterday (when I didn’t check), there were two birds in the southwestern alcove today: a Tennessee Warbler (AHY-U, fat = 2) and a Painted Bunting (SY-U <probably female>, fat = 2).
There was also a bonus at the Food and Ag Products Center: a window-killed Yellow-billed Cuckoo and a trapped Black-and-white Warbler. The warbler flew off fine as I approached.
I found a trapped Clay-colored Sparrow today in the southwestern alcove. Upon release in the relative safety of a nearby shrub, the bird flew off another 5m or so to another shrub, where it perched strongly.
Less lucky was the Magnolia Warbler I found in the northwest alcove. This bird, a female with fat = 3, was just the second of this species documented on this project.
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.
I actually discovered it on my 8/20 survey, but this poor little bird on the 20th was already seething with maggots so I’m comfortable calling it an 8/19 casualty. This was a second year male. Check out the feather wear on his primaries. He was headed south to molt and then continue on further south.
