I'm a drummer with a red cap, with a black body and white face; you may see me in trees

I build up castles, and I tear down mountains. I make some men blind, and I help others see. What am I?

In heights where eagles dare to glide, the summit's where the stars reside. A mountain's crown, a pinnacle's crest, the zenith of the earthly quest.

I have one partner for life, but I do not have words to tell them. I am known for My unique rock collection.

I have no mouth, yet I repeat what you say. I have no feet, but I travel far away. You can find me in mountains, halls, or caves, But only when your voice behaves.
