LIVING WITH GULLS – TRADING OF FOOD AND PREDATION IN THESANDWICH TERN STERNA SANDVICENSIS
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 […]
Adaptive seasonal trend in brood sex ratio: test in two sisterspecies with contrasting breeding systems
Sandpiper (Actitis hypoleucos) Science Article 1 abstract Evolutionary theory predicts adaptive adjustment in offspring sex ratio by females. Seasonal change in sex ratio is one possibility, tested here in two sister species, the Common sandpiper and the Spotted sandpiper Actitis hypoleucos and A. macularia. In the monogamous Common sandpiper, males are the most competitive sex. […]
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 […]
