This 2014 Dutch video is about ringing young Sandwich terns in Utopia nature reserve on Texel island.
Translated from Ecomare museum on Texel island in the Netherlands:
First terns’ eggs – 05-05-16
In late April the first Sandwich tern egg was seen on Texel. That was in the nature reserve Wagejot. Meanwhile, there are also eggs in the nature reserve Utopia. That is extra fun because these parent birds can be viewed via the Beleef de Lente webcam.
Sandwich terns at the Slufter, Texel: here.
