New avian friend!

We recently changed bird seed. The bird seed is Morning Song Backyard Bird Blend®. I am not too sure what it is the Brown Thrasher likes, but he is at the bird feeder all the time. It even jumps on the feeder! I’ve never seen a Brown Thrasher do that, and I’ve had bird feeders for 20 years! I think it’s the peanuts it likes. No matter what it’s eating, we enjoy watching our new bird friend! What do you all think he’s after?
