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...
