Kestrels are the most common bird of prey in Europe, although their numbers have declined in Britain over the last few years. Their habit of hovering, particularly near motorways, means they are also one of the easiest to spot. Whilst hovering they have the extraordinary ability to keep their head totally still, even in strong winds. This allows them to pinpoint and catch small mammals by sight alone. If prey is abundant, kestrels sometimes kill more than they need and cache what they don’t eat.
