Pretty views of the woods
Next we heard about a variety of birds, specifically insect-seeking birds in trees. There was a yellow-bellied sap sucker that drills holes into trees and eats the sap and insects drawn to it. There was also a giant woodpecker called the pileated woodpecker (think Woody the Woodpecker) that's drumming can be so loud that it often sounds like someone striking a tree with a hammer.Linear peckings from yellow-bellied sap suckers

Near the end of the hike, we also learned a lot about something called a gall. It's defined as an "abnormal outgrowth of plant tissues and can be caused by various parasites, from fungi and bacteria, to insects and mites." From the way I understood it, it works like this. Every wonder what happens to mosquito's in the winter? In the late fall, they bite plants, plants produce a chemical that creates sort of a pod or outgrowth on itself, that then traps the insect inside. In the spring, the insect then bites it's way back out to haunt us. Flipping weird. However, very inventive, and highly cool.
