I'm George Barrowclough and I investigate spotted owls. These magnificent birds live in the western United States, where they nest in the largest, oldest trees. I am worried that northern spotted owls may become extinct because the forest that is their home is being cut down.

I analyzed DNA taken from blood samples of northern spotted owls and California spotted owls to see if these bird species are different. I concluded that they are. The government is considering my DNA evidence as they figure out how to preserve the northern spotted owl.
