Why do we need the night?

Why do foxes need darkness? Foxes are crepuscular and nocturnal animals. This means they are primarily active in the early morning hours, at dusk, and during the night. They feel safe in the dark and can hunt undisturbed. Their sharp senses, excellent hearing, and keen sense of smell are perfectly adapted to nighttime conditions.

Hedgehog are nocturnal animals. They roam their territories after dark in search of food or shelter. They often travel several kilometers in one night. Artificially lit gardens and parks disturb hedgehogs while they search for food. In addition, day- and night-active robotic lawnmowers can cause serious injuries.

We need light to live. But we find ourselves in a state of constant light that seems to be shifted: During the day, we stay indoors and expose ourselves to too little daylight, which is necessary, among other things, for the production of vitamin D, which is so important for us. At night, we expose ourselves to too much artificial light. A clear rhythm between light and dark, which is urgently needed, is no longer recognizable...

There's something magical about the night sky. The world of constellations, planets, and galaxies is fascinating.

Increasing light pollution makes it more and more difficult to see the stars and endangers the cultural heritage of "stargazing".

Those interested in observing the stars can find what they're looking for on these portals.

With the right preparations and a little hint…

The European tree frog (Hyla arborea) is familiar to most people from fairy tales or as a weather frog. However, very few have actually seen one in nature. Why is that? Because of its lifestyle. It is a good climber and prefers to live in bushes or trees, perfectly camouflaged by its green color.

Anyone who wants to experience the concert of tree frogs…

A true master of camouflage , that's the nocturnal European nightjar (Caprimulgus europaeus), also known as the European nightjar. It is so well camouflaged that it is almost impossible to spot, even during the day.

Exceptionally maternal . There are about 1000 species of spiders in Germany. Wolf spiders form their own family among these species. The common night wolf (Trochosa terricola) likely gets its name from its hunting method, as it doesn't spin webs but hunts by sight. Its prey includes insects such as ground beetles, grasshoppers, and fly larvae, but also other insects…
