Feathers in the meadow

While on a patrol to the far bog last week or so, we found this large feather in a meadow near the bog. Some cursory research did not come up with any identity of the source specie.


Proceeding along the meadow, we came across this substantial collection of feathers indicating some fairly large bird ended up here, literally.
For scale, these are 9 inches or more in length. We have speculated they may be turkey but the volume and size of these feathers suggest at least a big bird, or more than one?
We did not examine the high grass underneath the feathers, or the surrounding area, for other remnants; the Murphy did not seem to think there was much here, aromatically speaking, I guess.
