When is the best time to observe red deer or similar?

Hello,

many years ago I was able to observe a roaring stag in the evening mist during a hike – very impressive.

Now I would like to repeat the experience with my daughters.

QUESTION: When is the best time to experience this? When do the stages roar? What time of day?

Is the time of year right?

A relative time would suffice as an answer, eg: – "Mostly in the evening 1 hour after sunset" – "Also in the morning approx. 1 hour before sunrise" – "At dusk in the morning and in the evening towards sunrise or sunset"

It would be best if mornings were also a suitable time. That would be better for the hiking route.

We are hiking in the Eifel / Hohes Venn Nature Park.

If you have any idea what time is best, possibly also to see other animals, please reply.

On the last tour in the High Fens / Hochmoor we only saw a frog as the largest animal. But the route was also different.

Many thanks for the answer, LG Werner Pühringer
