Fretting Wings

Looking close to the branches, I can see the fretting of the little wings. The way it moves is different from other birds'.

"It's me!"

"I can get to the suet after the Oregon Juncos, 

Yellow-rumped Warblers, and all the bigger birds.  

I have to be super quick; otherwise, they will kick me out.  

Tough to be a wee little bird."
