22 September 2017 – Mourning Warbler

I’m mourning the loss of another one today – this AHY female I found at the northwest alcove. She was fat (=3) and healthy at 12.5g.

 

This was the unofficial 315th casualty on the project and, for a new sobering record, the 44th this year. The previous annual high was 41. We’ve surpassed that already in 2017 and, for us, migration is really just ramping up.

18 September 2017 – Wilson’s Warbler

The Mourning Dove remained intact this morning. There was also an apparent AHY female Wilson’s Warbler at the southeastern alcove. She was fat (=3) and healthy at 9g.

1 September 2017 – Ruby-throated Hummingbird

Late in the afternoon, OSU grad student Megan Roselli brought me this HY-male Ruby-throated Hummingbird in a cup.  She had just found it at the northeast alcove (where it wasn’t when I had checked this morning).

29 August 2017 – Ruby-throated Hummingbird

I missed this bird on my 30 August check but was lucky enough to meet the reason why: OSU grad student Aurora Manley found this HY male Ruby-throated Hummingbird on the 29th (sometime after my check) and took it in to nurse it back to health. Unfortunately, it did not survive.

24 August 2017 – Mourning Warbler and Chipping Sparrow

On the heels of an impressive southbound flight last night,

. . . I found two casualties this morning.

There was a HY Chipping Sparrow in the northwest alcove.  The bird had evidently been stepped on or perhaps run over by a maintenance vehicle. I left it in place for a removal trial.

Also, near the main north entrance (actually at a west-facing facade in the corner) was a Mourning Warbler. The bold eyering and long undertail coverts looked tantalyzingly like a Connecticut Warbler. It was, however, an AHY-U Mourning Warbler. The bird was 13.5g and bulging with fat (3).

 

This was the 10th Mourning Warbler on the project.

 

 

 

 

 

 

 

 

 

21 August 2017 – Ruby-throated Hummingbird

I started my walk to class on this first day of the fall semester finding this window-killed Yellow Warbler at the Food and Agricultural Products building.

After class, I ran my normal survey, finding this Ruby-throated Hummingbird (HY male with fat = 1) at the southwest alcove.
