30 June 2017 – three casualties

I was out of town from 21–30 June and no surveys were run during that time.  On June 30th, however, I heard from Dawn Brown and Corey Riding that there were three casualties at the southwestern alcove of the Noble Research Center: a badly decayed Northern Parula (adult male), a female Ruby-throated Hummingbird, and a female (with brood patch!) Indigo Bunting.  It’s possible that the bunting came in on the 30th, but the others were clearly killed prior to that date. (Photos by Dawn Brown.) This is officially the first Northern Parula found on the project.

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.

12 May 2017 – Indigo Bunting

Will Jessie alerted me to this SY male Indigo Bunting at the southwestern alcove. I left the bird in place for several days (and the ants had gotten to it before I did).

9 May 2017 – Indigo Bunting and Chipping Sparrow

Found another SY male Indigo Bunting today at the main north entrance, plus the survey’s first Chipping Sparrow at the southeast alcove.

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).

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!

22 September 2016 – Indigo Bunting

The photos illustrate how obvious it is to find many of the carcasses at the Noble Research Center.  Today it was an Indigo Bunting in the southeast alcove.

This was a hatch-year bird and probably a male owing to the faint bluish tinge in the wings and tail.  Were those blushes of color resigned to the upper tail coverts, female would be a bit more likely.  Fat = 0 on this bird.
