ELI5: Explain Like I'm 5

Courtship display

A courtship display is like when a boy wants to impress a girl by doing something cool. When birds or other animals want to find a mate, they show off their fancy dances or beautiful feathers, like a peacock spreading its colorful feathers to make a girl feel impressed. It's like when you put on your favorite superhero costume or do a cool trick on the playground to impress your friends! Basically, it's a way for animals to say, "Look at me, I am strong and healthy and would make a great mate!"
