It's odd that you can see the borders between Belgium and France for various birds (like the swift and cuckoo), same for the border between Germany and Poland.
I wonder why that is? There are no topological features defining these borders. Maybe the data is normalised in some way across countries?
Die Visualisierung auf dem Eurobirdportal ist wirklich toll gemacht. Es ist spannend zu sehen, wie Echtzeitdaten aggregiert werden, um die Migration über ganz Europa so detailliert nachzuvollziehen.
On desktop, I think you have to click on the tiny icon next to the currently visible bird's name ("select new dataset") and pick one from the list that appears on the left side of the screen.
"Real-time" been +seconds for decades at this point, pretty different from the "original" meaning, so "live" having the same treatment doesn't feel that out of place.
