This 2014 video from the Netherlands says about itself:
Nest of Eurasian spoonbill or common spoonbill (Platalea leucorodia) containing eggs and chicks.
Author: Natuur Digitaal (Marc Plomp); Stichting Natuurbeelden
In Dutch nature reserve Nieuwkoopse Plassen, the first young spoonbills of this year’s nesting season have hatched.
You can see them on a webcam, here.
You will probably also see and hear black-headed gulls close to them.
