By 2050, Zurich Zoo will consist of 11 large-scale habitats on its existing area of ​​27 hectares.

A massive mega birdhouse planned by a Swiss zoo is to go ahead after fed-up neighbours abandoned their protests.

Plans had been put on hold after people living next to Zurich Zoo sued trying to halt the 11,000-square-metre (118,403 square feet) 'Pantanal Voliere' aviary in 2021.

Now, after losing a series of planning appeals, the demonstrators have told the zoo they won't take an appeal to Switzerland's Federal Administration Court.

Initially scheduled to be opened in 2025, the legal battle has delayed the new enclosure until 2028.

Experts say the new enclosure will replicate wetlands in South America and as well as hosting endangered birds but also anteaters, tapirs and tamarins.

The complainants, who were not named in local media, had claimed the zoo's building application was invalid because of procedural errors.

Planners say the aviary will be 35 metres (115 feet) high and almost a third bigger than a Premier League football pitch.

Its name comes from Pantanal, one of the largest tropical wetlands in the world straddling Brazil, Paraguay and Bolivia.

Director Dressen explained: "By strolling through the aviary, visitors will become a part of the Pantanal community. The aviary will enable them to be on eye level with the birds and experience biodiversity."
