Very sad news from Zie-zoo. Last night 10 sea gulls were killed. They were shot from outside the park. According to Dutch news sites, 6 herring gulls, 2 black-tailed gulls and 2 lesser black-blacked gulls died - of which at least one young bird. (The zoo only had 3 herring gulls, so I suspect 6 black-tailed gulls and 2 herring gulls were shot). No information on the shellducks who share the aviary with the gulls.
