The heavy storms that hit the Dutch Wadden Islands in June has caused permanent damage to the bird population.
The storm hit the island birds late in the breeding season, meaning that survivors, already weak and exhausted from fleeing to safety, were unable to start a second nest.
Common Redshank and Common Terns were the most affected by the storms, but exact numbers are not known as these birds are not monitored as closely as some other breeds.
At least 100 Spoonbill nests were destroyed in the storms, and 150 Spoonbills drowned.
Of approximately 5000 Black-headed Gull nests, 2000 were lost.
