Thousands of birds recently dropped dead in areas of Colorado and New Mexico, but researchers say there's more than one factor to blame.
While researchers are still investigating the cause, the sudden appearance of dead birds in Colorado is likely due to the sudden temperature plunge and heavy snowfall observed last week across parts of the state.
Colorado Parks and Wildlife tweeted on Monday that there's also some speculation that high winds and poor air quality could be contributing factors.
We're getting reports of a lot of dead birds in the Durango and Gunnison areas. Likely caused by the sudden temperature plunge and snow last week. Observers in New Mexico report thousands of dead birds. Speculation there is a combo of weather, high winds and poor air quality.— CPW SW Region (@CPW_SW) September 14, 2020
Two of the local spots where the dead birds have been widely reported include Durango and Gunnison areas.
Thousands of dead birds, both resident and migrant, are also being found throughout the state of New Mexico.
