For red deer, chamois and ibex, a fast approach from above always means great stress.
Most sensitive times:
Winter (energy-sapping rutting season, meagre food) : November to February
Fawning season: May/June to September
if herd or a single animal or mother with fawns are visible
keep your distance, no swooping in that direction
No circling above the animals
Winter is the most difficult time for wildlife. Food is scarce and meagre.
Chamois and rock deer spend most of their time on sunny slopes and windblown
ridges in order to find food, most important is energy saving.This means that
they limit their activities to the most important ones, they reduce their
metabolism and rest as much as possible. Disturbances have a particularly
strong effect during this time, because they have to keep metabolism
up again and again. Due to the increasing number of winter sportsmen
it is becoming more important to raise the awareness about the situation
of wild animals.
