Identify a bird by its feather
It seems to be the secondary feather of a Waxwing, a bird from the Genus Bombycilla, like Bombycilla cedrorum:

Actually, that red tip gives the bird its name (from the Wikipedia link):


  They have unique red tips to some of the wing feathers where the shafts extend beyond the barbs; in the Bohemian and Cedar waxwings, these tips look like sealing wax, and give the group its common name.


Therefore, the possible species are the Bohemian waxwing (B. garrulus)...



... and the Cedar waxwing (B. cedrorum):



However, since the secondaries of B. garrulus normally have a white area next to the tip...



... I'd guess that your feather belongs to B. cedrorum.

In conclusion

Besides the white patches in the feathers of Bohemian waxwings, OP just confirmed that the range of the Bohemian waxwing doesn't match. Therefore, this feather belongs indeed to a Cedar waxwing.
