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

 

 

7 May 2017 – Indigo Bunting and trapped Yellow Warbler

With special guest stars James O’Connell and David Mallen, today’s survey turned up a male Indigo Bunting and a trapped Yellow Warbler at the main north entrance. (No photo of the warbler; it was a male.)

Let’s take a closer look at that Indigo Bunting:

 

The multiple obvious molt limits on this bird illustrate two generations of feathers on the same individual, some of which grew in last summer and some which have come in quite recently.  This confirms the age of the bird as second year (SY).

4 April 2017 – trapped Song Sparrow

No casualties yet, but I’m up to the 3rd trapped bird of the new year: a Song Sparrow in the northwest alcove.  This one was stunned – or exhausted – but before I could get any closer than about 3m it flew away strongly – good sign!

 

This bird was likely riding a wave of migration that really lit up the radar last night (as linked from Paul Hurtado’s birding page). Check out the big blue blobs in Oklahoma from a little after 11 pm last night:

Keep your eye on that slug of rain and storms (the green, yellow, and red) in the OK Panhandle, though.

Now check out the line of rain and storms that moved in overnight and set up shop on the Kansas border.  This is from a bit before 6:00 am, and nobody moving north through our state kept on moving through that!  This is a classic setup for a “fallout” of birds.  More storms today followed by strong north winds tomorrow will likely keep some staging migrants around for a few more days.

3 April 2017 – trapped Common Yellowthroat

I found this rather early fellow right in front of the doorway to the southeast alcove this morning. He’s a gorgeous, ASY male Common Yellowthroat with fat score = 1. He was dazed enough that I caught him but alert and feisty in the hand, and he perched well when I moved him to a safe spot.  In addition to being one of history’s all-time great yellowthroats, he has the distinction of being the 100th “trapped” bird that I’ve been able to move or shoo away from the Noble Research Center.  If even one of them recovered enough to fly on and live out its life then every one of these walks around the NRC has been worth it!

Unfortunately, something went screwy with my camera and this is the only surviving photo:

20 March 2017 – trapped Northern Cardinal

Spring kicked off today with the first collision victim of 2017: a trapped Northern Cardinal at the northeast alcove.

 

He was a bit stunned, but alert in the hand and he perched strongly in the dense cover where I moved him away from the building.  Beautiful ASY male; I hope he makes a full recovery!

30 October 2016 – 2 Grasshopper Sparrows

I found a trapped Grasshopper Sparrow at the main North entrance to the NRC today, and then a second dead bird at the southeastern alcove.  The trapped bird took quite a bit of effort to eventually guide away from the building, but the time was worth it if I was able to keep it from ending up like its comrade.

17 September 2016 – trapped Northern Waterthrush

So far, it’s exclusively been the southwestern alcove causing the problems this fall. That’s a bit ironic and potentially problematic, as I’ve completed more window treatments there than anywhere else on the building.  However, none of the four birds that has ended up there has been found in front of a treated window, leaving open the suggestion that the treated windows have not cause any casualties, even if casualties have occurred at the partially treated alcove.

This morning, I found the first bird actually in front of a treated window pane: a Northern Waterthrush. The hopeful difference is that this bird was ALIVE.

Above right – Yep, that little white dot in the photo on the right is waterthrush splay in front of the window where I first encountered the bird.
