Searching for woodpeckers has been quite easy. They leave behind holes that you can categorize as to which woodpecker made them according to their size and shape. They have different drumming sounds and distinctive calls. Most abundant in our frequented places are the Northern Flicker and the Downy woodpecker seen below. The woodpeckers have an amazing ability to prevent concussion due to their spongy bone skulls, and their long tongues that cushion their brain inside their skulls. Absolutely amazing!
