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.
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:
He’s pretty blue, but his molt limits reveal him to be a second year (SY) male.
Those three big feather visible on the folded wing are the tertials (aka, secondaries 7, 8, and 9 from outer to inner.
Tertials from above. On the right wing, 7 and 9 are brownish and worn but 8 is fresh and blue/black. Tert #8 has been replaced but 7 and 9 are originals from when this bird was a baby last summer. On the left wing, 8 and 9 have been replaced but #7 is original.
Paper plate and packing tape makes it a bit easier to see some things.
Left wing: alulua, greater coverts, secondaries 5 and 6, and terts 8 and 9 have been replaced. Primary coverts, primaries, and secondaries 1,2,3,4, and 7 are orignal.

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).
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.
