Things have been busy in Flickerdom the last few weeks. The last I posted, the previous male had disappeared and the female had decided to start over again with a new male. This is very obviously not the same male because he’s what’s known as an “intergrade.”
In the Eastern U.S. all Northern Flickers are yellow-shafted, meaning they have yellow wing and tail linings. Eastern males also have black mustache stripes and both sexes have a red crescent on the nape of the neck. Their faces are brown with a grey crown. In the west, however, Northern Flickers are red-shafted, meaning they have red wing and tail linings. The Western male’s mustache is red. Neither sex has a red nape crescent and their faces are grey with a brown crown.
Here in the eastern half of Colorado, yellow-shafted and red-shafted Flickers tend to mingle and interbreed, so while most Northern Flickers look like the red-shafted subspecies, you can get some that display traits of both subspecies. This new male, whom I’ve been thinking of as Mr. Gold, has a red mustache and no nape crescent like a red-shafted, but he has very conspicuous yellow linings to wings and tail.
The female and this new male have been mating pretty regularly and just this morning she laid her fifth egg. The male has been keeping the eggs company all night and both parents have been trading off egg duty during the day, though the male has been spending most of the time in the box. He’s a pretty industrious fellow. Maybe to stave off boredom, he’s been pecking away at the sides of the box to add new wood chips to the floor.
As I mentioned previously, Northern Flickers will lay between 6 and 8 eggs on average. They can also lay many more, however, because they’re “indeterminate layers.” This means that if their eggs are destroyed or removed, the female will keep laying for an “indeterminate” period of time. So I guess we’ll just have to see how many this pair ends up with!
