The zoo based in Winkhill, Staffordshire has gone into administration after failing to attract visitors to the 30-acre site.
Founded in 1991 by Mark Rubery, the zoo is home to over 200 species of rare and endangered birds. As a registered charity, a wealthy benefactor has kept the zoo open for a number of years but unfortunately, the zoo has now had to enter administration and seek a buyer.
Phil Wood, Managing Director of appointed administrators, Barringtons Corporate Recovery, said "If no-one comes forward then ultimately it will have to close, the stock will have to be dispersed and we will sell it as some land."
Back in 2011, the zoo was on the brink of closing down but was saved by financial backing from the business and public.
Wood believes the charitable trust is still a viable and charitable business so a trading administration is the best option if a buyer can be found.
Update: 28th March 2014 - to date, there have been over 60 enquiries for Blackbrook by potential buyers and it's hoped one will be found very soon.
