I’m Marc Dantzker, a biologist at the Cornell Lab of Ornithology. What you’re looking at now is a lek, specifically a Greater Sage-Grouse lek. A lek is a gathering of males on traditional breeding ground where they’re all displaying to attract mates. The males are the ones with the spiky tails. The females are out there too; they’re the smaller grayer ones. It looks like chaos, birds running around helter skelter but in reality it’s an organized, highly structured social interaction. I’m gonna walk you through it. Each and every one of those females will choose a mate but only a few of the males will be chosen. To us, all the males basically look the same. The question is how do the females choose and why are so few of the males successful.End of transcript
