I have branches, but no leaves, and tellers, but no tales. I hold your interest, but offer no opinions. What am I?

I'm an aviary type and yes my bones are hollow. At least my name carries no innuendo, like that little weirdo swallow.

I can be baked but I'm not bread. When I'm hot, people want to get rid of me. I'm a component in chip manufacturing but I'm not silicon. When there are many of me that are small, we're insignificant. When people sit on a couch, they can become a kind of me.

If you get a call to ask if it's running, you'd better go catch it!

How much wood would two woodchucks chuck if they agreed they both would chuck wood?
