Here are some shots of random Peruvian woodpeckers. There were about 24 species of woodpeckers in the areas we birded; we saw ten species.
Note the nest cavity below the bird. Yes, it was active. In fact, we found several active nest cavities.
Woodpeckers are highly specialized. Their bills and heads are designed to hammer away at wood. Their tails have stiff feathers called retrices to allow them to prop themselves in position. Their talons are designed to grasp tree trunks. And they are indispensable to the health of a forest.
Larger woodpeckers, and especially the males, are incredibly colorful, too. Always fun to see.
