Here's a pile of northern flicker feathers. This one you have here fits right in: http://goingtoseedinzone5.files.wordpress.com/2012/10/northern-flicker.jpg

ok i think i found something look at the very back tail feathers of this red bellied woodpecker see if any of those were like what you have here. http://b50ym1n8ryw31pmkr4671ui1c64.wpengine.netdna-cdn.com/wp-content/blogs.dir/11/files/2013/05/Blog_Red-belliedWoodpecker_HowardCheek_356425.jpg

Here is a wonderful references for bird feathers: http://www.fws.gov/lab/featheratlas/

it also might be a woodpecker but their feathers a kind of stiff and are generally small.

this could be a down feather of an owl, like from an area on the stomach. I've never seen anything like it
