Are these the flock cameras I keep reading about?

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.

Why the number of birds decreases and then increases? Is it because migration or due to non-observable previous times?

Yes and people don't like them because some want to use them to stop migration.

Looks like birds really like Iberia to stay during cooler times, just like many UK, Deutsch and French citizens ;)

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?

If this is based on bird spotters, I'd say the national bird spotting organizations don't report or watch for the same birds.
