On way to cliffs at Lybster to have a look for Dolphins, heard commotion in gorge by bridge.
Quick scan with bins saw what looked like a wagtail with yellow feathers (Grey Wagtail poss). Then lost sight of it, while looking around saw this bird being harassed by blackbirds a Tawny Owl.
Sorry bad picture poor light, 150 feet away in shrub.
