This lizard species stress-eats to cope with noisy US Army aircraft
Living in a neighborhood with lots of noise can make you jittery, especially if you’re a lizard that’s just a few inches long. It’s no wonder that lizards exposed to noise pollution from low-flying fighter jets have resorted to stress-eating. Colorado checkered whiptails — striped and patterned lizards that live only in southeastern Colorado — are an all-female species that reproduce asexually. They also endure considerable noise from US Army flyovers.
By comparison, ground readings during flyovers surged to 112 dB — louder than a jackhammer and just above the average pain threshold for humans. During checkered whiptails’ reproductive season in 2021, the scientists observed dozens of lizards during flyovers. They caught, weighed and measured the lizards, collecting blood samples from 82 females.
