I spotted this young (you can tell by the length of its beak) kingfisher (Alcedo atthis, 🇩🇪 Eisvogel, 🇵🇱 zimorodek) far from the river and its parents, waiting to be fed. Although it can fly, it hasn't learned to hunt yet and is dependent on its parents for food. But the parents already have new chicks, which have priority for feeding. The start of an independent life is hard for birds.
