An increasing visitor.

Ravens are gradually re-colonising Hertfordshire. Having previously bred in the County it was, in common with other parts of England, driven to extinction by Gamekeepers, Farmers and, collectors of their skins, eggs and, young for pets. Prior to 2006, when they bred again in the County, the last known breeding in Hertfordshire was at Brocket Hall near Welwyn in 1846. They are now increasingly being seen flying over Stevenage.
