13 September 2015 – Nashville Warbler

Today I found a window-killed Nashville Warbler in the southwestern alcove.  The brownish cast to the upperparts and tapered rectrices suggest a HY bird, sex undetermined.  Fat = 2.  I have included a radar image of last night’s flight on a rare evening that felt a lot more like October than September.

9–12 September 2015 – no casualties

While there we no casualties during this period, we did have some interesting observations:

On Thursday 10 September, I found an olive/yellow warbler flying around and perching in local trees  near the southwestern corner of the Noble Research Center.  The bird flew strongly, was not trapped, and did not let me get close enough for a decent look and identification.

Overnight Thursday and from about 2:00 am to 9:30 am on Friday 11 September, a powerful cold front and storm pushed through our area with damaging winds and hours of lightning and torrential rain.  I checked the NRC around 8:00 am –  during one of those lightning-lit downpours and found no casualties.  Later that day, Corey Riding found this bedraggled Mourning Warbler near the southwestern alcove, but far enough from the building to make us hesitant to consider it a window casualty:

12 September was busy around the NRC with tailgaters preparing for a 6:30 pm football game.  I found a local Mourning Dove tucked against the wall near the northeastern alcove (not trapped) and a younger bird (recently fledged) that had died near the east end of the south portico.  The fledgling looked too young to have been a window casualty so I did not count it.  I also flushed a warbler from within the patio area on the east side of the rotunda. In my fleeting view, the bird was yellowish with a noticeably olive rump.
