I would have to say Winged World,which was situated at Heysham Head,near Morecambe in Lancashire,and which was in operation from 1966 until 1979.I was a keeper there for several years,and while largely unmentioned nowadays,this was a one of a kind place where rare softbills were bred and standards of dietary development and husbandry were second to none.Along with former colleagues I'm gathering information for a major project to remember and celebrate the achievements of this amazing facility,and we have the full cooperation of the first Curator,the eminent aviculturalist Clive Roots who now lives in Canada.Any memories,recollections,photographs or memorabilia associated with the Winged World and Childrens Zoo would be really appreciated by us,and will of course be fully acknowledged. Winged World set high standards and in its day was the best in the UK.It should be more widely appreciated.
