Ruddy Turnstone (Arenaria interpres) Science Article 4 abstract The ruddy turnstone, Arenaria interpres interpres, a migratory Korean bird, was proved to be a natural definitivehost for Gynaecotyla squatarolae (Digenea: Microphallidae). The ruddy turnstone was found dead at the seashore of Okgueup,Gunsan-si, Jeollabuk-do. The intestinal tract was examined, and 98 unknown flukes were recovered. Min Seo […]

Spring migration of Turnstones from the Banc d’Arguin in Mauritania
Ruddy Turnstone (Arenaria interpres) Science Article 3 abstract The majority of the Turnstones Arenaria interpres wintering on the Banc d’Arguin, Mauritania, probably breeds in N. Scandinavia and NW. Russia, but a sizeable proportion may be derived from Greenland and NE. Canada. Juveniles did not prepare to migrate to the breeding grounds, but in the course […]
Biometrics of Turnstone Arenaria interpret migrating in autumnthrough the Gulf of Gdansk region
Ruddy Turnstone (Arenaria interpres) Science Article 8 abstract In this study we analyse biometrical data of 69 adult and 389 juvenile Turnstones Arenaria interpres caught during autumn migration when passing through the Gulf of Gdansk in the period 1983-1999. Adults had significantly longer wings than juveniles. WLODZIMIERZ MEISSNER and LESZEK KOZIROG, ORNIS SVECICA 11:181-188, 2001 […]
AGONISTIC BEHAVIOR OF RUDDY TURNSTONES TOWARD SHORT-BILLED DOWITCHERS FORAGING FOR HORSESHOE CRAB EGGS
Ruddy Turnstone (Arenaria interpres) Science Article 5 abstract Ruddy Turnstones (Arenaria interpres) may be highly aggressive toward other species of shorebirds, including the Short-billed Dowitcher (Limnodromus griseus) (Burger et al.1979), but agonistic behavior of turnstones toward dowitchers at specific foraging sites isnot well documented. Turnstones are opportunistic foragers and may use many feeding methods. DOUGLAS […]
Interactive effects of time and vegetation on reproductionof redshanks ( Tringa totanus) breeding in Wadden Sea salt marshes
Redshank (Tringa totanus) Science Article 1 abstract As shown for various species, nesting waders are non-randomly distributed on wetlands and preferentially select riparian nest-sites adjacent to limnic or marine waterbodies. Studying the redshank Tringa totanus, we tested the hypotheses that, in a coastal wader species which conceals its clutch in vegetation, predation and hatching success […]
Digestive bottleneck affects foraging decisions in red knots Calidris canutus. II. Patch choice and length of working day
Red Knot (Calidris canutus) Science Article 15 abstract When prey occur at high densities, energy assimilation rates are generally constrained by rates of digestion rather than by rates of collection (i.e. search and handle). As predators usually select patches containing high prey densities, rates of digestion will play an important role in the foraging ecology […]
Southward migration and fuel deposition of Red Knots Calidris canutus.
Red Knot (Calidris canutus) Science Article 10 abstract We compared the differences between spring and autumn in migration speed, fuelling rates and fuel loads of migrating Red Knots Calidris canutus. As a basis we used ringing data from Ottenby Bird Observatory, southeastern Sweden, collected 1948-2003, with morphometrical data from 1990-2003. Numbers ringed varied between 0 […]
Body transformations, condition, and survival in Red Knots Calidris canutus travelling to breed at Alert, Ellesmere Island, Canada.
Red Knot (Calidris canutus) Science Article 11 abstract This paper reviews the nutrient storage dynamics and body changes of Red Knots Calidris canutus islandica during migration through their final spring stopover area in Iceland and after arrival on the breeding grounds in the northeastern Canadian High Arctic at Alert. In Iceland, Knots not only accumulate […]
Two estimates of the metabolic costs of antibody production in migratoryshorebirds: low costs, internal reallocation, or both?
Red Knot (Calidris canutus) Science Article 5 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 […]
Fuel use and metabolic response to endurance exercise: a wind tunnel study of a long-distance migrant shorebird
Red Knot (Calidris canutus) Science Article 2 abstract This study examines fuel use and metabolism in a group of long-distance migrating birds, red knots Calidris canutus (Scolopacid ), flying under controlled conditions in a wind tunnel for up to 10 h. Data are compared with values for resting birds fasting for the same time. Plasma […]
