Preview--A golden eagle is so large and powerful it can bring down a red deer calf, survive the most brutal winters in the Highlands of Scotland and breed successfully for up to 40 years. Yet sightings are rare and a mere glimpse of one gliding over the frost-tipped mountain peaks is a gift.

Travel to the mountains and glens of Scotland, to see the majestic golden eagle in its element when the NATURE series airs Shadow Over The Sun: A Story of Eagles, Sunday, May 27 at 8 p.m. (ET) on PBS (check local listings). For more information, visit http://www.pbs.org/nature
