Pecking order?

Early this morning a raccoon knocked my bird feeder to the ground, and helped himself.

A red-tailed hawk grabbed a squirrel from the largest of my oaks, and flew away.

The resident red fox unearthed a mouse, and ate it in front of my window.

A catbird flew by with a butterfly in its mouth.

An ant carried a dead stink bug over the stone step to my cabin.

Is this called a 'pecking order'?
