Since 1998, Zurich Zoo has supported the Bat Conservation Foundation, which coordinates the protection of bats in 19 cantons, with the support of the Federation. besidesJoint operation of the care stationIn the event of an emergency on its territory, the Zurich Zoo also supports dOther bat protection projects.

In cooperation with the enterprise, it is sIt is obligated, for example, to preserve the roosts known to the only active flying mammals, in church spiers, ancient roofs, or hollow trees. In addition, the foundation installs bat boxes in suitable places, in order to provide them with additional shelter.

harmful light pollution

This is because since the middle of the 20th century, the number of bats in Switzerland has decreased sharply. Their shelters are becoming increasingly scarce, due to the replenishment of granaries or the lack of old timber in the forest. In the flight paths between their lodges and their hunting grounds, they also suffer from light pollution,Urban sprawl due to roads and noise pollution.

And in hunting grounds, insects, their favorite prey, are disappearing more and more, because ofIntensificationAgriculture, pesticides andDrying wetlands.

Single males, colonial females

In Switzerland, bats constitute the richest group of mammals with thirty species. More than 1,400 species are described in the world. While the males in most species live singly, the females in the summer form the so-called lWeekly roosts (colonies where young are raised), are called aBritish reach toup to 1000 the animals, to meOcean.

Finally, in the winter, the Zurich Zoo winds up all the original bats into hibernation. In doing so, they significantly reduce energy metabolism. For example, by lowering the heart rate from 1,100 beats on the fly to a few dozen per minute. They can reach an age approaching 40 years.

Many wild animals can transmit diseases toa leg. ItIt works especially on swine flu, bird flu, MERS, SARS and Covid-19. Bats are considered a “reservoir” for a large number of virusesZurich Zoo explains, In his press release,. In fact, the researchers, working with the Bat Foundation, detected many different viruses in our original samples. However, SARS-CoV-2 nNone of them.

Usually the virus needsAn intermediate host and cannot be transferred directly fromHuman bat. againstis also a caseA virus similar to SARS-CoV-2, which was discovered in a Chinese bat species. In principle, however, direct contact with bats should be avoided, as they can, like all land animals, transmit diseases.
