Birds are so smart. I am not convinced of the bird's motivation. But is enjoyable to ponder about.

Very avid little creature. Fun and fascinating. Thanks for posting.

Strangely fascinating to watch.

Actually she gathering nesting material. Many birds will do this.

Thought maybe it felt inadequate in some way so adding ‘feathers’?

What a neat bird. I wonder what her name is?

They carry materials to make nests.

Beautiful little birdie.
