The birds recently took up residence in a custom-built nest on the top of the Swiss reformed church in the town of Aesch in the canton of Basel-Landschaft.
The arrival of the birds is good news for the community. The stork nest was built in 2013 for 18,000 Swiss francs (€15,600), with most of the money coming from donations.
The pricey nest features a special door that allows direct access from the interior of the church tower to the nest itself. This makes tasks such as bird banding much easier.
However, despite the costs, the nest has basically stood empty for five years.
In 2016, the church decided to turn off its church bells during the during the February–March stork breeding period – a move that now appears to have paid off with the new arrivals.
The church bells will now remain silent indefinitely so that the birds are not disturbed.
Bruno Gardelli of the organization Stork Switzerland welcomed the decision to turn off the bells. But he also told Swiss news site 20 Minuten that the birds did not appear to be particularly sensitive to noise.
Storks are regular summer visitors to Switzerland. They return to the country in early spring after wintering in southern Europe and northern Africa.
