The male Greater Sage-Grouse courtship display is an elaborate and impressive performance that takes place during the breeding season in early spring. Here's an overview of the display:
The male Greater Sage-Grouse starts by making a series of deep, resonant thumping sounds by inflating air sacs on its chest. This creates a drumming noise that can be heard from far away and is used to attract females and intimidate rival males.
Once he has attracted a female, the male will start his courtship display. He will puff out his chest and spread his wings, revealing bright yellow air sacs that are surrounded by white feathers. He will then strut around the female, making a series of popping and bubbling sounds with his throat.
As the display continues, the male will fan out his tail feathers and hold them erect, revealing a striking pattern of black and white feathers. He will then strut and dance around the female, sometimes jumping into the air and making a buzzing noise with his wings.
The courtship display can last for several minutes and is an impressive sight to behold. It's a testament to the male's strength, health, and overall fitness, and is used to attract the most desirable females and establish dominance over other males in the area.
