Plenty of kestrels and buzzards hunt over the grassland in the dunes, which is hoaching with rabbits. A peregrine roosts nearby on Fidra Island - I was lucky enough to be "buzzed" by this wonderful bird while walking on nearby Traprain Law and watched it attack a pigeon (which somehow managed to escape).
But the coin won't stay here long. I met On His Bike at the cache and he has taken it further on its travels.
