An article about Northern Flicker intergrades?

Kenn Kaufman wrote a well-illustrated article about
identifying flicker intergrades several years ago
in _American Birds_.

------------Gail Spitler asked:

Does anyone have a reference for an article on Northern
Flicker Intergrades? I think it was published about
3 years ago, maybe 4. I have checked Birding, which was
my first guess, with no luck. This was an identification
article in a birdwatcher type magazine, not in a technical
journal.
