Lake Constance - Wilderness on the Water
Available on Prime Video, Amazon Freevee
No other European destination has as many incoming and out-going flights as Lake Constance: it's the main hub for migratory birds in Western Europe. Over 300 different species pass through every year: that's more than a quarter of a million birds. Lake Constance is so large that, standing on one shore, the Earth's curvature prevents you seeing the opposite bank.
