This video is called Pied Avocet – Recurvirostra avosetta.
In Golden Raand magazine, published by the Groninger Landschap conservationists in the Netherlands, fall 2013, p. 24, there is an interview with a warden of Polder Breebaart nature reserve.
It turns out that many Breebaart avocets have been ringed in Spain.
Some barnacle geese, seen in Breebaart, are from Svalbard; others from Siberia.
