I saw a porcupine while on a group night hike. The porcupine was in a tree eating the new buds from the tree. It started to climb down, but when it heard us it stopped and waited till we left.
I heard and saw a male sapsucker pecking into some trees. I could clearly see the straight line of hole the bird make in the tree.
I heard this bird calling in the morning. The call and the rust on it's head gave it away.
