Wetlandbirds.

Beautiful sundown, no wind. All kinds of wetlandbirds, gathering in the shallow water. On the opposite riverside traffic sounds.
Typical wetland birdsounds of the Netherlands. In this case the birds are gathering one evening in a large number in springtime, you can hear a lot of the same birds.
It’s sad to know that some species are decreasing in number. So what you hear is rather unusual these days.
