The Sage Grouse
The sage grouse may seem boring to look at, but that’s because you’ve never seen one when it’s in display mode. The males have fascinating mating and display rituals that make you question how they came up with these intricate practices in the first place. The sage grouse stand out from the rest because they have two air sacs on the front of their chests that they puff out when they’re ready to show off. It can appear obscene, but remember that these are the males who don these air sacs, not the females.
