I once spent a weekend studying flickers south of the TriCities.
I only counted birds I could see with scope. Duplications unlikely.
Intergrades are more common in winter.
Here's the summary.

Subject: [Tweeters] Flicker intergrade: how common?
Hi Tweets,
Today we had an apparent intergrade Northern Flicker male at the suet: his
thin but distinctive red nape crescent caught my eye. Other marks were a red
moustachial stripe and yellow shafts showing at the wing edge. It's the
first intergrade I've observed; I read that they are fairly common, but I
wonder how common this variation is. Web research doesn't turn up much
detail. Any input appreciated.
Thanks,
Kristi Hein, Anacortes
