This is a tail feather. The asymmetry suggests that it was an outer tail feather vs. an inner tail feather--this distinction exists in most species of bird and a species argument based on this alone would be tenuous at best.
This would be a tail feather and not a secondary wing feather because the bend in the shaft is localized at one location towards the bottom of the feather. Secondaries are typically curved throughout the shaft.
This is an owl feather based on the fuzzy surface of the feather and the fact that this pale orange color is very common in typical owl (Strigidae) species.
Finally, the best species match for location and pattern would be Long-eared Owl.
Tail feathers are at the bottom left of the photo.

So in conclusion this is a tail feather from a Long-eared Owl.
