For the city, this necessary closure is, of course, very regrettable. The aviary has been a popular feature of Mainz City Park for many years and is a familiar and beloved place for many visitors. This makes the decision to suspend operations for the time being all the more difficult. However, the safety of the animals, staff, and visitors is our top priority.

Initial measures temporarily improved the situation over the summer. However, it was not possible to permanently eliminate the mold infestation. The building’s aging structure facilitates the further spread of mold. Since inspections revealed the presence of mold species that are hazardous to the health of both humans and animals, further measures must now be taken consistently.

Starting in mid-November, the birds will therefore be moved to other zoos or temporarily housed in aviaries operated by the Department of Parks and the Environment. The aviary will then be closed.

A structural and energy-efficiency renovation of the aviary is, in principle, possible. According to an initial estimate by the architectural firm commissioned for the project, the costs would amount to approximately 700,000 euros. The necessary funds are to be requested for future budgets. 

A specific date for the start of the renovation cannot yet be given. It remains the city’s goal to once again offer its residents a birdhouse in the future.
