This 2010 video is about the Blauwe Kamer nature reserve in the Netherlands.
Today, the conservation organisation Utrechts Landschap reports on birds in that reserve in 2017.
That year, 71 bird species nested there. Spoonbill nests rose from 37 in 2016 to 42. Nesting grey herons and great cormorants decreased a bit. Other species: water rail, kingfisher, bluethroat, nightingale, and marsh warbler.
