The WCS has released a set of images (below) caught by WCS scientist currently studying in Alaska. The images are from an area near the Ikpikpuk River in the National Petroleum Reserve – Alaska (NPR-A). Studies are currently be completed to see whether human-subsidized predators (Artic fox, raven and glaucous gulls) are having a greater impact on migratory birds nesting in the area. Before human presence in the area the landscape was very sparse but human construction has allowed animals such as the Arctic fox to den near buildings and ravens and their young, which are usually rare in the area to use the buildings for protection and nesting. With an increase rate of survival they are possibly able to raid more nests than in previous years.
