A single plaintive call from a neighbouring fallow draws attention to a Golden Plover; as it runs to take wing a whole flock of its fellows, previously unseen, starts up to bear it company.

Of small birds the Meadow Pipit and Wheatear are perhaps most characteristic of the high sheep-walks and mountain moorlands. Every rocky "kopje" has its pair of wheatears.
