Impact of Common Kingfisher on a salmon population during the nestling period in southern England
The effect of fish-eating birds on their fish-prey populations has been a matter of concern to conservationists, anglers and fishery interests, especially when both bird and fish species have conservation status and are afforded some protection by law. Understanding the predator-prey interactions wi...
