4 June 2018 – Indigo Bunting

Found this Indigo Bunting today at the main north entrance. Looks to be an ASY-male, with fat = 0.

8 May 2018 – Indigo Bunting

Corey Riding reported that the Lincoln’s Sparrow has been removed.

Corey also found this apparent AHY-F Indigo Bunting at the main north entrance. (I took these photos on May 9.)

30 April 2018 – Indigo Bunting

I found this ASY male Indigo Bunting at the southwestern alcove this morning. Fat = 2 and possible impact mark on the culmen.

28 September 2017 – Our first Savannah Sparrow, a trapped yellowthroat, and some bonus birds

Since Monday night, we seem to have received at least 5 inches of rain here in Stillwater.  That’s great as I’ve been lamenting the lack of even clouds for a few weeks. The system that brought the rain might have kept birds bottled up to our north because once it cleared last night (Wed.) there was one heck of a flight.

Of course, attempts to correlate window collision mortality with big radar echoes of migrating birds are fraught with confirmation bias.  There are plenty of big flights that result in no dead birds on my rounds, and I’m a lot more likely to check “last night’s radar” on a morning when I find multiple casualties.  Today was one of those days.

I walked to the Noble Research Center on a route that took me past the long row of windows on the southern side of the Food and Agricultural Products Building, aka, FAPC. This is just across a parking lot from the NRC and I’ve made several incidental finds there.  Today, these “bonus birds” numbered three: an Ovenbird, a Common Yellowthroat (collected) and, around the corner, a female Indigo Bunting that had been there for at least a few days. So before I even made it to the NRC, I encountered 3 window-killed birds.

The yellowthroat was an apparent AHY-male, with fat = 2 and weighing in at 12 g.

 

At the NRC was another surprise.  Surprisingly, after all these years and considering how common these birds are as migrants and wintering residents, I found the project’s first Savannah Sparrow, in the northwest alcove.

 

 

There was also a trapped Common Yellowthroat at the main north entrance and another Savannah sparrow flitting around – through not trapped – just west of the southern portico entrance. The Savannah Sparrow was AHY-U, weighing 18g with a fat score = 2.

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).
