When I first watched birds, decades ago in the Yorkshire Dales, I never saw stonechats. There were plenty of whinchats, a species whose numbers have tumbled to the point where their conservation status is Red and I rarely see them today. When I lived on the west coast I knew I would see stonechats at St Bee's Head in Cumbria. And in Lincolnshire they were relatively common on The Wash bird reserves and were occasionally seen further inland in winter. Today I know I can guarantee seeing stonechats on the Malvern Hills. Not only are they easy to see at that location, you can also hear their distinctive call that sounds like two stones being knocked together.
