The pheasant forms the backbone of both driven and walked up game shooting in Scotland today. Native to Asia and the extreme south-eastern tip of Europe, the pheasant has been widely introduced across Europe and North America. It was known to the Romans, who may have introduced it to Britain. The Normans certainly kept it to supply food. It naturally adapts to a broad variety of habitats. Around the Cateran Trail they are usually found in woodland, hedgerows, field margins and open farmland with adjacent cover. Large numbers are reared and released into managed woods well before the shooting season starts.
