Bird Calls In Berlin Voliere

Birds chirping, police sirens in the distance and the birds reacting slightly, human visitors making bird sounds, car horns in the distance, children talking in the distance, more birds singing, traffic noise in the distance, train (s-bahn) driving in the distance. Best part was when a tourist on a bike was using a squeaky toy "bell" and the birds answered its call. Voliere video: https://youtu. Be/jiwu8ytv9rarecorded with zoom h2n.
