Abstract:
Ringed Plovers Charadrius hiaticula L. were studied on South Uist, Outer Hebrides, from 1.11.83 to 30.12.86. Internationally important numbers were present throughout the year. Winter to summer residency was approximately 68%. The winter population was male-biased, and concentrated on 'feeding beaches' near rocky features of the coast. Site fidelity was high. The feeding beach invertebrate fauna was of low diversity, but exceptionally high density and biomass. Ringed Plover weights showed a variable midwinter peak. Individuals which disappeared between winters were lighter per unit body size than those which did not. Spacing behaviour varied from non-aggressive 'free-feeding' to the sharing of territories by individuals which then bred together inland. The probabilities of individuals holding territories varied with sex, age, size and environmental conditions. Fewer long-term to intermittently territorial males disappeared between winters than would have been expected from their proportion in the population.
