The Massif de Platé is inhabited by numerous mammals and birds, adapted for a life in altitude. In the course of a walk, it is common to encounter a troop of male Ibex (bouquetins), to surprise a marmot, 'raise' a ptarmigan (Lagopus mutus) or watch a hovering kestrel (Falco tinnunculus). Some may be lucky enough to observe the bearded vulture (Gypaetus barbatus) a spectacular mountain vulture present in the area. Around the chalets, the stoat (Mustela erminea) hunts voles, while the yellow beaked alpine choughs, champion of aerial acrobatics, waiting around the chalet to pounce on any abandoned cheese crust. The strident and repetitive cries of marmots fill the valley, warning of dangerous attacks by the golden eagle or the fox.
In the morning, the silhouette of the female Ibex with their kids stand out on the ridges of the Pointe de Platé, while the rare passing chamois graze on the lower slopes. As for the discrete mountain hare (Lepus timidus) or the weasel (Mustela nivalis), principally nocturnal, these show themselves but rarely. Finally, along the cliffs and steep slopes, a lucky wanderer may encounter a wallcreeper (Tichdroma muraria) or a rock thrush (Monticola saxatilis), rare little sparrows inhabiting mountain walls.
