US: Live stream captures 2,000 pregnant rattlesnakes in 'mega-den'

Thousands of pregnant rattlesnakes are coiling in a Colorado "mega-den," viewable via Cal Poly's "RattleCam." This rare live stream, led by Professor Emily Taylor, offers an unprecedented look into the lives of expectant rattlesnakes, aiming to shift perceptions and provide unbiased scientific data. The snakes will remain in the den until September, when males return for hibernation.
