This is a video from Finland, about a great egret at a river in winter. The river is surrounded by ice and snow, but it still flows; a bit similar to the river of the dipper nest I saw in Finland.
Warden Hans Breeveld reports today from Oostvaardersplassen nature reserve in the Netherlands.
There are 171 great egret nests.
This spring, there is at least one eaglet in the sea eagle nest.
