@mrc These are solid reasons. By the way, bird sighting databases (Ornitho, Cornell/Naturalist, etc.) are publicly visible, but often only to a limited extent. Ornitho.de hides reports of rare or endangered species. So, if you’re interested in observing a Hoopoe in Germany, for example, in places other than Kaiserstuhl, you have to rely on word of mouth.
