Evening wander, by Shantullich farm.

Extra - earlier this wee thing was buzzing about overhead, and the pilot seemed to be taking the speed down to near stalling, for some reason, before heading off. Further investigation later, and it's a Cavalon gyrocopter or gyroplane, by RotorSport UK. Could make out the identity code on the tail (G-CKVZ).

Edit: Came across an air equivalent of the ship tracking and port activity websites I'm used to, it's Flightradar24, and might be of interest if you'd like to know what's flying above you and where it's going, i.e. you're bored! So some UFOs may be identifiable...
