Common or Hoary Redpoll?

Happy 2017 everyone!
Found this redpoll in Kapuskasing last week but am not sure how to ID it. I think it has dark streaking making it a Common but am not sure how dark is dark relative to the Hoary.

Probably a Common, but without seeing the rump and undertail coverts it's hard to make a conclusive ID.

Thanks Thomas.
Not sure if this shot is helpful but here goes

COmmon and Hoary Redpoll are probably best considered a single species, but regardless this is well towards the Common end of the spectrum. Brownish and heavily streaked all over, including on the undertail coverts

Thanks for your help guys.
I didn't know that in some circles they are considered the same species.

Here is an article based on relatively current research at Cornell University examining differences and similarities of Common, Hoary and Lesser Redpolls.  https://www.allaboutbirds.org/from-many-one-how-many-species-of-redpolls-are-there/

Very interesting read. Thanks for sharing it... but if I ever do see a "Hoary" I'd be too excited to not count it separately
