Please could anyone identify these tracks? Not sure whether it's mammal, bird, insect or amphibian!
Location: SW Scotland. Outside of velux roof window. (Placed piece of white card behind window to get photo.) August 1013. Looked for excrement, no signs. Looks like two separate tracks, one smaller than the other (50p included for scale.)
PS Suggestions so far: mouse, pterodactyl.
PPS Can't possibly clean window til it's identified!
