Pied Avocet - Recurvirostra avosetta
These ones you can also see here in the wild in marshes, lakes and shoreline. I wonder if they would stay in the icey winter if given the chance to migrate. i think this one is quite Ok with thei ice though.
Seen at Planckendael zoo, on February 2021.

It is a migratory species and most winter in Africa or southern Asia. Some remain to winter in the mildest parts of their range, for example in southern Spain and southern England.
