Sandwich Tern (Sterna sandvicensis) Science Article 3 abstract The low-lying, sandy areas along the Dutch coast offer important breeding opportunitiesfor Sandwich Terns Sterna sandvicensis. Throughout the twentieth century SandwichTerns nested here in fluctuating numbers. The Dutch population suffered from a majorkill in the 1960s due to pesticide pollution causing the number of breeding pairs todrop […]

Reflections of a specialist: patterns in food provisioning and foraging conditions in Sandwich Terns Sterna sandvicensis
Sandwich Tern (Sterna sandvicensis) Science Article 1 abstract Highly specialised piscivorous seabirds, like S andwich Terns Sterna sandvicensis, have limited capacity to switch to alternative prey species when the availability of a particular prey species is low. Therefore, variations in the diet of such species are likely to reflect fluctuations in food availabi lity. We […]
Arrival and weight gain of Red Knot Calidris canutus, Ruddy Turnstone Arenaria interpresand Sanderling Calidris alba staging in Delaware Bay in spring
Sanderling (Calidris alba) Science Article 3 abstract Delaware Bay is an important spring staging area for shorebirds migrating north along the easternAmerican coast, with birds relying heavily on Horseshoe Crab Limulus polyphemus eggs duringtheir stay. While many species use the Bay, three species are of particular interest: Red KnotCalidris canutus, Ruddy Turnstone Arenaria interpres and […]
Sanderlings (Calidris alba) have a magnetic compass: orientation experiments during spring migration in Iceland
Sanderling (Calidris alba) Science Article 1 abstract The migratory orientation of sanderlings (Calidris alba) was investigated with cage experiments during the spring migration in southwest Iceland. Sanderlings were exposed to 90 deg counterclockwise-shifted magnetic fields under both clear skies and natural overcast. Clear sky control tests resulted in a northerly mean direction, in agreement with […]
Spring migration of Sanderlings Calidris alba through SW Iceland: Wherefrom and whereto?
Sanderling (Calidris alba) Science Article 2 abstract The spring migration of Sanderlings Calidris alba through southwest Iceland was studied in 1989-1990. Additional information was collected during the spring seasons of 1985-88 and 1991. Ringing recoveries and controls, together with a large number of sightings of color-ringed birds, revealed that many Sanderlings staging in Iceland in […]

Ruddy Turnstone (Arenaria interpres) Science Article 6 abstract Delaware Bay is an important spring staging area for shorebirds migrating north along the easternAmerican coast, with birds relying heavily on Horseshoe Crab Limulus polyphemus eggs duringtheir stay. While many species use the Bay, three species are of particular interest: Red KnotCalidris canutus, Ruddy Turnstone Arenaria interpres […]
Two estimates of the metabolic costs of antibody production in migratoryshorebirds: low costs, internal reallocation, or both?
Ruff (Philomachus pugnax) Science Article 1 abstract We measured the costs of mounting a humoral immune response using two novel antigens (tetanus and diphtheria) in two shorebird species (Scolopacid ): Red Knot (Calidris canutus, measured in autumn) and Ruff (Philomachus pugnax, measured in spring). Metabolic rate was measured during the preinjection phase, at the building […]
Biometrics of Ruffs Philomachus pugnax migrating in spring through southern Belarus with special emphasis on the occurrence of
Ruff (Philomachus pugnax) Science Article 2 abstract In spring, the Ruff Philomachus pugnax passes through European inland sites in large numbers. Birds from eastern and western parts of the breeding range may differ in biometrics, but data on this species in eastern Europe are scarce. The aim of this study was to describe the biometrics […]
