How much would egg and duckling predation need to be reduced to reverse declines of ground-nesting waterfowl in Finland? A demographic scenario analysis

Abstract Populations of water- and wetland-associated birds have declined globally due to multiple pressures, including habitat loss, climate change, and predation. Ground-nesting waterfowl are particularly vulnerable to predators, and the spread of invasive mammalian predators l...

Spring migration passage advances can be counteracted by range shifts

Long-term passage records of migrating birds from fixed observatories are widely used to infer spring migration phenology. Yet migrants recorded at a site need not represent a constant mixture of populations over time. Spring onset and optimal arrival occur later at higher latitu...
