Black-tailed prairie dogs once occupied a territory hundreds of miles wide, stretching from Mexico to Canada. We have now converted nearly all of that grassland to cropland for wheat, corn, other crops; pastures of European grasses; or paved it over for homes and shopping centers.

Fluctuating Numbers of Wintering Raptors Reflect a Cold Northern Winter and a Locally Fractured Environment
Since 1983, volunteers with the Boulder County Nature Association have monitored winter raptors.
