https://www.vogelwarte.ch/wp-content/uploads/2026/03/2580_1.jpg16001200The Great Black-backed Gull is the largest and most massive gull in Europe. It keeps to coastal habitats all the year round and only occurs sparsely in Central European inland areas. Similar to other gulls, favourable food sources have led to an increase in population size and range of this opportunistic omnivore.
