Northern Flicker Breeding Season

A couple weeks ago I told you about a fencing duel between Northern Flickers; over the last couple weeks it's apparent that Northern Flicker breeding season is under way. I'm seeing and hearing way more of these woodpeckers than I usually do. (They sound a little like their bigger Pileated Woodpecker cousins, which in turn sounds slightly like a maniacal laugh to me.)

If you're out in the woods this week, look (and listen) for these guys. I'm hearing them a lot right now.

Our Northern Flickers used to be called Yellow-shafted Flickers (denoting yellow wing/tail feathers seen best during flight) while the western US had a species called the Red-shafted Flicker (denoting reddish wing/tail feathers). Eventually ornithologists determined that the Yellow-shafted Flickers and the Red-shafted Flickers interbreed sufficiently willingly (where both species are present) that the birds evidently considered one another to be the same species. This led to ornithologists to merge these 2 former species into one species, the Northern Flicker (AKA Common Flicker). 

Our (yellow-shafted) Northern Flickers have a bright red spot on the back of their heads. The males additionally have a black "mustache". You can't really see any yellow in my picture, but the red spot and black mustache are pretty evident.

When I saw the flicker in the 2nd picture below, I wondered if this might have been a female in a nesting cavity, but when I processed the pictures and saw the black mustache it was clear this was a male. Both males and females are involved in clearing out a tree cavity for a nest; perhaps this was a husband flicker warning other birds that this tree cavity is occupied.
