My first was the Snowy Owl on Anglesey a few years back. I arrived about a hour before dusk with knowing news that it had dissappear not knowing where it had gone I was running around like an headless chicken. I was trudging back to the car having given up hope knowing it was going to be dark soon.Suddenly a Kestrel was making a racket so myself and the only other birder left went to investigate. After approaching closer there was the owl sat on a rock! After about a minute it got up and flew a great distance before being lost to view.I think this then disappeared for a few days before relocating to South Stack.
