From Natuurmonumenten in the Netherlands:
At the Schorren nature reserve, outside the Wadden sea dike on Texel island, flooding destroyed birds’ nests, including 20 spoonbills‘ nests, 250 herring gulls’ nests and 30 oystercatchers’ nests. Rare birds such as 10 little tern couples, 5 Arctic tern couples and and a marsh harrier couple also lost their eggs and chicks. Fifteen young spoonbills were able to reach the narrow strip of land along the dike and survived the flood.
