waterbird counts on large water bodies: comparing ground and aerial methods during different ice conditions.the aerial and ground methods of counting birds in a coastal area during different ice conditions were compared. ice coverage of water was an important factor affecting the results of the two methods. when the water was ice-free, more birds were counted from the ground, whereas during ice conditions, higher numbers were obtained from the air. the first group of waterbirds with the smallest difference between the two methods (average 6%) contained seven species: mute swan cygnus olor, whooper swa ...201830038859
botulism in wild birds and changes in environmental habitat: a relationship to be considered.any human activity, even if aimed at the improvement of a natural area, can potentially affect wildlife, leading to possible short-term or long-term changes due to the human-wildlife interaction. in this study, a botulism outbreak which occurred in waterfowl in a nature reserve after a conservative environmental action is reported. more than 180 different species of wild birds, including seventy waterfowl species, live in the area. the wildlife reserve rangers built an artificial pond equipped w ...201931779284
