Create riddles help

So on occasion I like to make riddles but surprisingly enough *lol* I don't get very many occasions to test them out on people. I want to see if they hold up or are any good. Can someone please read these riddles I've invented in my spare time and see if they can guess the answers? All, any suggestions you can come up with would be helpful.

1.)
Listen closely to what you will have heard
I wish to tell you of a most wondrous bird
It's all of metal, its call a whiny creak
It can be found at the crown of any peak
It swings around to tell you north
From south to west to east and so forth
It has no legs and in place it is pinned
what kind of bird can only move downwind?

2.)
I am something you desperately want but never at night do I haunt.
From far away I can be seen but when you come closer I disappear in between.
What am I?

3.)
I chitter, I chatter, I swing, I climb,
I throw gross things, and my manners are less than sublime.
What am I?

4.)
I am full of life, Possess many deep mysteries no one alive knows
and have journeyed with many people.
What am I?

5.)
You use me often. You hit me often.
Yet I can never feel downtrodden.
You see me everyday. I protect you,
sometimes I hinder your way.
What am I?

6.)
I am pure black but colored like bubbles in light.
I am a black rainbow that flows.
What am I?
