PhysOrg Posted October 7, 2019 Share Posted October 7, 2019 The white-tailed sea eagle is known for reacting sensitively to disturbances. However, research into which factors have which effects on the animals and how these impacts influence breeding success has so far only just begun. A research team led by Dr. Oliver Krone from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) has now measured concentrations of the hormone corticosterone and its metabolic products in white-tailed sea eagles in northern Germany and correlated these values with potential causes of "stress". They found that the levels of corticosterone in the birds' urine are higher the closer a breeding pair's nest is to paths or roads. From this, the scientists derive implications for the management and protection of white-tailed sea eagles, in particular for protection zones around the nests. The study was published in the journal General and Comparative Endocrinology. View the full article Link to comment Share on other sites More sharing options...
