Spring/Summer 2017 was busy

As I’m about to head out for a conference this week, spring and summer monitoring comes to a close.  I’ll begin August 2017 the 9th consecutive year of (mostly) daily monitoring for window casualties at the Noble Research Center on the campus of Oklahoma State University in Stillwater, Oklahoma, USA.

It’s been a busy spring.

Beginning Mar 1st, here’s what has turned up at the Noble Research Center.

Dead Birds

  1. Indigo Bunting – 5
  2. Painted Bunting – 5
  3. Ruby-throated Hummingbird – 3
  4. Lincoln’s Sparrow – 2
  5. Mourning Dove – 2
  6. Nashville Warbler – 2
  7. Orange-crowned Warbler – 2
  8. Baltimore Oriole – 1
  9. Chipping Sparrow – 1
  10. Eastern Meadowlark – 1
  11. House Wren – 1
  12. Northern Parula – 1
  13. Tennessee Warbler – 1
  14. Yellow-billed Cuckoo – 1

That’s 28 individuals of 14 species, and damn, that is disheartening.

On the plus side, my commitment to checking almost every day has put me in position to save a few birds by getting them safely away from the building and taking them someplace secure to rest and recuperate for a bit. I can’t guarantee that all 6 of these survived the ordeal, but they seemed to be in good shape when I last saw them:

  1. Northern Cardinal
  2. Common Yellowthroat
  3. Mourning Dove
  4. Song Sparrow
  5. Yellow Warbler
  6. Carolina Wren

10 May 2017 – Painted Bunting and Nashville Warbler

Today I found a SY Painted Bunting at the main north entrance and a Nashville Warbler at the northwestern alcove.

19 April 2017 – Nashville Warbler

This one was twofold odd – the bird was found in an odd spot and I’ve clearly overlooked it for a few days given the state of decomposition.  The beetles, slugs, etc. were all over it.

9 October 2016 – Nashville Warbler

The current gap of collisions I’ve enjoyed over the past week or so was interrupted this morning by a beautiful male Nashville Warbler in the northeast alcove.  He was an AHY bird with a fat score = 2 on my 3-point scale. This is the 11th Nashville Warbler I’ve found on the project.

19 September 2016 – Nashville Warbler

That southwestern alcove continues to get a workout this fall, but again, the unfortunate victim was found in front of untreated glass panes.

Today it was a hatch-year (HY) Nashville Warbler; sex undetermined with fat score = 2.

 

When I found the bird in position on the cement as indicated in the above photo, it had already been heavily scavenged by ants. I moved the carcass to a location on the grass on the north side of this southwestern alcove (see photo, top right) to set up a removal trial.

21 August 2012 – Nashville Warbler and Ruby-throated Hummingbird

I found a very fresh Nashville Warbler (HY female; fat = 2) at the north entrance and a Ruby-throated Hummingbird (HY male) just a few feet from the Painted Bunting carcass.   The ants had gotten to the hummingbird, so I decided to leave it in place to see how long it lasts.  Here is the warbler:


Here’s the spatial distribution of casualties thusfar:
