As much as we don't like to admit it, We've probably all had a moment like this before. We don't like to admit it because it's just another example of nature outsmarting us, of animals getting so wily they can read us like a book and con us out of our own property. That look on his face is not one of anger, but disbelief. He's just realized that he might not be on top of the food chain.
Seagulls are probably the best animals out of all of them in giving us this feeling of mental inferiority. We've seen seagulls walk into a convenience store, brazenly pick up a packet of chips, and fly out. We've had seagulls fly in over our shoulder and take entire cheeseburgers out of our hands. Basically, we know exactly how you're feeling, buddy.
