An interview about HoverOverUs • Short-toed-Eagle and about the research and conservation of Short-toed Eagles has recently been given by me and been published on the Interviews section of the European Raptors website. This site is a relatively new project developed by Markus Jais and dedicated to the biology and conservation of European Raptors.
