There are flickers here all year round, but numbers seem to increase in the fall, presumably northern or montane birds moving southward and downward. You seldom walk more than a block or two without hearing their "keeew!" call, usually from the top of a tall tree. Still, they go mostly unnoticed until they land on a lawn and start foraging for ants. "What's that big bird?"
Trying to photograph a foraging flicker with a digital camera as famously unpredictable as Mr. Hesitation calls for perseverance and a large memory card. The bird forages: peck peck peck peck head-up-to-look-for-cats peck peck peck peck head-up-to-look-for-cats, etc. It is during the head-up-to-look-for-cats split-second that you hope the shutter will open. You end up deleting a lot of images.
