Oystercatcher Haematopus ostralegus Winter Mortality in The Netherlands: The Effect of Severe Weather and Food Supply (original) (raw)

The study investigates winter mortality patterns of Oystercatchers (Haematopus ostralegus) in The Netherlands, focusing on the influence of severe weather conditions and food availability. Analysis of beached bird surveys from 1969 to 1996 indicates a correlation between winter severity, cold days, and prey biomass that significantly affects mortality rates. It highlights the role of food scarcity, particularly due to overfishing, on the increased vulnerability of Oystercatchers during harsh winters.
