The rocks around the Zugspitze are a habitat for chamois, whilst marmots are widespread on the southern side of the massif. At the summit there are frequently alpine choughs, drawn there by people feeding them. Somewhat lower down the mountain there are mountain hare and the hazel dormouse. Alpine birds occurring on the Zugspitze include the golden eagle, rock ptarmigan, snow finch, alpine accentor and brambling. The crag martin which has given its name to the Schwalbenwand (Swallows' Wall) at Kreuzeck is frequently encountered. The basins of Mittenwald and Seefeld, as well as the Fern Pass are on bird migration routes.
