Neu-eine-Stunde
April 19, 2026, Birdwatching Hide at Flachsee Waterbird Reserve

Yesterday, through a highly magnified pair of binoculars on one of these islands, I was able to observe five cormorants in close harmony: Magnificent! The birdlife here is truly diverse - a magnifying glass is actually a must. But the photos stored here by Komoot users are also great in this highlight - especially the photo of the kingfisher, which I unfortunately haven't had the chance to see yet...

Beautiful bird viewing point. There are really nice photos early in the morning, as well as in the evening. But you can also see the birds really well during the day.
