31 May 2017 – Indigo Bunting

Chalk up another second-year male Indigo Bunting as a window-kill victim at the Noble Research Center. This bird had fat = 1 and CP = 2.

28 April 2017 – Indigo Bunting

Sad to think that this spectacular specimen of an ASY male (fat = 2) Indigo Bunting safely crossed the Gulf of Mexico a few days ago but could not safely navigate the Noble Research Center.

 

 

Indigo Buntings, of course, have no blue pigment.  Blue is produced by birds through light reflectance – it’s structural color, not pigment.

You might think, then, that Indigo Buntings would look really cool in UV light.  They don’t, unless you think charcoal looks cool!

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.

19 October 2016 – Lincoln’s Sparrow and Common Yellowthroat

Flight calls abounded last night as I walked the dog at least thrice.  Those calls – little tsips! and tseeps! sounded to me like sparrows flowing from the north after three straight days of strong winds blowing from the south. A quick check of Paul Hurtado’s Nexrad radar birds page confirmed a big push in Midwest and the Plains:

Sadly, with that push came two casualties at the Noble Research Center: a Lincoln’s Sparrow (AHY-U with fat = 2) at the southwest alcove and a Common Yellowthroat (AHY-M with fat = 2) at the northwest alcove.  (Apologies for the shaky portrait on the Yellowthroat – it looked clear on my phone.)

 

Although casualties continue to pile up in the west alcoves where I’ve treated several windows with ABC Bird Tape, it has so far appeared to be the untreated panes in those alcoves that are claiming the casualties.

20 August 2015 – Yellow Warbler

Yesterday’s powerful cold front gave us this morning’s Octoberish morning, and a big flight of migrants last night. Check out this explosion of migrants in the Plains from around 10:30 last night:

At least one of those migrants, a HY-U (prob female) Yellow Warbler, made it no farther than Stillwater last night.  She was in great shape with fat = 2.

22 March 2015 – trapped Northern Cardinal

In the first action at the NRC since a trapped Orange-crowned Warbler way back on Oct. 28, I found this Northern Cardinal in the southwest alcove this morning.  He let me grab him but judging from his squawking and the strength with which he flew away he’s just fine.
