Ravens are found throughout Alaska's diverse landscapes and human settlements. Because they are incredibly adaptive they can survive in a variety of places including Alaska's North Slope oil fields. For more than 30 years, they have used structures and food resources in the oil fields to survive and reproduce. Throughout their range, ravens are notorious for eating the eggs and chicks of other birds. In 2002 University of Alaska Fairbanks researchers Dr. Abby Powell and Stacia Backensto began to investigate the impacts of ravens on tundra-nesting birds within the oil fields. During the last two years they have been able to monitor and track ravens using satellite and radio telemetry and individuals marked with colored wing tags. Observations of these marked birds are critical to this research because they provide information about seasonal movements and behavior. Your help is important!
