Found in the metroplex, so it can’t be anything TOO exotic. I suspect a hawk.
Theories?

Round object is a US nickel coin for scale.
Looks like an Owl feather to me. Here is a website where you can do your own identification : http://www.fws.gov/lab/featheratlas/idfeather.php
You’ll like the website for its detail and variety
I would guess sparrow hawk.
That’s my first guess too. AIUI the easy way to tell owl feathers from non-owl feathers is two details,
But unless your really familiar with feathers in general or have a non-owl feather for comparison the differences might not be that obvious.
(The texture is pretty obvious in the pics at the above site.)
The right color and fuzzy, owl.
The right color and not fuzzy, not owl.
CMC fnord!
If it’s a hawk or an owl, the fathers are illegal to posses.
I think it’s probably from afemale American Kestrel.
Beautiful plumage.
And that feather site is a great one Colibri!
There’s a rabbit warren near where the feathers were found, so a raptor makes perfect sense.
Enforcement logistics aside* does that really mean that, according to both the spirit and the letter of the law, I’m required to throw the feathers into the trash can? 
Serious question (with an admittedly snarky tone) because I’m genuinely curious about that aspect.
*I’m picturing sitting home alone, peacefully reading a book, when suddenly the feds come pounding on my door and storming in with guns at the ready.
Rabbits would be pretty big prey for a Kestrel. They mostly go for small birds and mammals and large insects.
Technically you could apply for a Salvage Permit.
However, the odds of being prosecuted for having a single molted Kestrel feather in one’s possession are probably small.
