In Bavaria, you can observe most Central European Alpine species and abundant bird life. Some of the best birding areas in the Alpine region are Allgäu, the North Tyrolean Limestone Alps, the Karwendel Mountains, and parts of the Salzburg Limestone Alps in the Berchtesgaden region. Most of them can't be reached during winter though. The best period starts in May and lasts till July. In summer as well Ismaniger, Moosburger, the Echinger reservoirs, and the lakes Ammersee and Starnberger See are worth a visit. The river valley region, the Lower Inn, the Danube near Aholfing, or the Donaumoos near Guenzburg are good to visit during the breeding and migration seasons—the spring and autumn period. There is also nothing special to see during winter. But in winter you can visit the Starnberger See, Chiemsee, and Ammersee. The most common bird species you can observe in Bavaria are Divers, Night Heron, Little and Great White Egrets, and many, many more.
