CuckYou.

The European Common Cuckoo is an asshole. Well, the technical term is a brood parasite. Basically, Mama Cuckoo will lay her eggs in another bird's nest, so that some schmuck of a pigeon or something gets stuck raising her kid. Papa Cuckoo is a sneaky fuck too, often he'll cause a distraction in order to lure the schmuck birds away from the nest so Mama can get in there and deposit her business (she has actually evolved to do this quickly and discretely). And Baby Cuckoo isn't innocent in this Jerry Springer-esque nonsense either, it's the skeeziest of the bunch -it hatches quicker than the schmuck babies, grows faster, and pushes the schmuck eggs and/or chicks out of the nest so it doesn't have to share regurgitated worms with nobody. It's born with that instinct. Ugh, kids are the worst.
Unfortunately, birds don't have access to DNA swabs and lie detector tests and sassy audience members to give them sage advice -which is a shame, because I would totally watch that show.

Just a thought.
