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 […]
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 […]
Predation by Kelp Gulls Larus dominicanus at a mixed-species colony of Royal Terns Sterna maxima and Cayenne Terns Sterna eurygnatha in Patagonia
Royal Tern (Sterna maxima) Science Article 2 abstract We studied the predator-prey interaction between Kelp Gulls Larus dominicanus and Royal Terns Sterna maxima and Cayenne Terns Sterna eurygnatha at Punta Leon, Argentina, from 1990 to 1992. Kelp Gulls were the main predator of tern eggs in all 3 years, accounting for 99% of observed predations […]
Mitochondrial Control-Region Sequences in Two Shorebird Species, the Turnstone and the Dunlin, and Their Utility in Population Genetic Studies
Ruddy Turnstone (Arenaria interpres) Science Article 1 abstract Because of its rapid rate of sequence evolution, al most strictly maternal mode of inheritance, and lack of recombination, mitochondrial DNA (mtDNA) is the molecule of choice both for studies of intraspecific sequence divergence (Wilson et al. 1985; but see Gyllensten et al. I99 1) and for […]
Populations migrations biometrics and molt of the Turnstone Arenaria interpres interpres on the East Atlantic coastline with special reference to the Siberian USSR population
Ruddy Turnstone (Arenaria interpres) Science Article 2 abstract Three populations of Turnstone were studied. Primarily a series of comparisons were made between the Canadian-Greenland population which winters mainly in western Europe ad the Siberian population which winters partly in southern Africa. There was no long term change in the size of the latter population over […]
The Ruddy Turnstone, Arenaria interpres interpres, a NewDefinitive Host for Gynaecotyla squatarolae (Digenea:Microphallidae)
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 […]
