Birdworld first opened its doors to the public in 1968 and was run as a family business by Roy Harvey, his wife and children. Throughout the next 28 years the park grew in size and expanded to include the Jenny Wren Farm in 1990. During the early 90’s, the next generation took over the day-to-day operation but in 1996 decided to move on to different ventures. It was at this time that neighbouring business owners, Denys E. Head Ltd, bought Birdworld to become the third division of their company, along with Forest Lodge Garden Centre and Garden Style.
Development of Birdworld continued throughout the next few years with the Terry Pratchett Owl Parliament, Silent Forest aviaries, Penguin Beach and Outback Landing becoming firm favourites with regular visitors.
