With the leaves off the trees, winter can be a good time of the year to do some woodpecker watching.
For most of us, the Downy and Hairy woodpeckers are probably the most observed woodpeckers during the winter months. They are quite similar, but the Hairy is a little bigger — about 7-10 inches in length, while the Downy is a little shorter, around 5-7 inches long. With both species, the males can be identified by the red patch on the back of their head.
As you might expect, North Dakota is not a woodpecker paradise. But even though our state ranks as the least-forested state in the nation, Robert Steward lists seven species of woodpeckers in his Breeding Birds of North Dakota: Downy, Hairy, Red-headed, Red-bellied, Yellow-bellied Sapsucker, Yellow-shafted Flicker, Red-shafted Flicker, and the Pileated Woodpecker.
When looking at the distribution maps of woodpeckers in bird guides, it becomes apparent that most woodpeckers are not big migrants. Most are permanent residents within their range, or perhaps are only summer residents in the northern regions of their range. One exception to that is the Yellow-bellied Sapsucker which spends the summer in our northern regions and winters in the southern states.
Although woodpeckers may be easily observed during the winter in bird feeders, it is often the sound of their “wood pecking” that first tips us off to their presence in the area. As most everyone knows, they may be hammering away on the trees for more than one reason:
- A quiet tapping is generally the sound produced when the woodpeckers are accessing insects.
- When they are establishing territories and attracting mates, the hammering is more accurately described as a drumming.
- It is the slower “whack, whack, whack” that generally indicates that a woodpecker is excavating a nesting cavity.
Woodpeckers are actually quite common in our area, and we have a few species that can provide some good entertainment, as well as help us better understand their biology and ecology. So be on the lookout for these interesting birds. They will reward you — and maybe even hammer out a message to you.
