Using a data set that spans almost 50 years Craighead Beringia South is contributing information to help assess the reality and degree of the apparent decline of golden eagles in the Intermountain West. The study area is in South Central Montana near Livingston. This area has an unusually high density of breeding golden eagles and information exists on this segment of the population dating back to 1963 from John J. Craighead's study. The study was continued in the 1990's by Craighead's son Derek. Today as the study continues this information makes up one of the oldest datasets on a breeding population of golden eagles in North America. This information gives us the unique ability to compare current and historic trends in order to accurately gauge the status of the population. Check out the 2011 Interim Report to learn more about the study and the latest findings.
