Incubation capacity and clutch size determinationin two calidrine sandpipers: a test of the four-egg threshold

Semipalmated Sandpiper (Calidris pusilla) Science Article 3 abstract Several groups of vertebrate taxa, including shorebirds, are unusual in that they produce a x number of offspring. The aim of this study was to examine whether the incubation capacity of western sandpipers (Calidris mauri) and semipalmated sandpipers (C. pusilla) limits their maximum clutch size to four […]

Site Safety and Food Affect Movements of Semipalmated Sandpipers(Calidris pusilla) Migrating Through the Upper Bay of Fundy

Semipalmated Sandpiper (Calidris pusilla) Science Article 2 abstract The upper Bay of Fundy is a critical stopover site for Semipalmated Sandpipers (Calidrispusilla) during their fall migration. However, little is known about factors that influence selection of feeding and roosting sites by these birds, or the extent to which birds move between different sites during their […]

The structure of aerial displays in three species of calidridinae (scolopacidae)

Semipalmated Sandpiper (Calidris pusilla) Science Article 1 abstract Sandpipers in the subfamily Calidridinae (Scolopacidae) breed in the Arctic and Subarctic. In all species, unpaired males engage in distinctive aerial displays. Such displays are described for three species: Dunlin (Calidris alpina L.), Semipalmated Sandpiper (Calidris pusilla L.), and Stilt Sandpiper(Calidris himantopus Bonaparte). EDWARD H. MILLER, The […]

Male traits, mating tactics and reproductive success in the buff-breasted sandpiper, Tryngites subruficollis

Buff-breasted Sandpiper (Tryngites subruficollis) Science Article 1 abstract Buff-breasted sandpipers use a variety of mating tactics to acquire mates, including remaining at a singlelek for most of the breeding season, attending multiple leks during the season, displaying solitarily ordisplaying both on leks and solitarily. We found that differences in body size, body condition, fluctuatingasymmetry scores, […]

Conservation status of the buff-breasted sandpiper:historic and contemporary distribution andabundance in south america

Buff-breasted Sandpiper (Tryngites subruficollis) Science Article 2 abstract We present historic and contemporary information on the distribution and abundance of BuffbreastedSandpipers (Tryngites subruficollis) in South America. Historic information was collated from the literature,area ornithologists, and museums, whereas contemporary data were derived from surveys conducted throughoutthe main wintering range in Argentina, Uruguay, and Brazil during the […]

Different migration strategies used by two inland wader species during autumn migration, case of Wood Sandpiper Tringa glareola and Common Snipe Gallinago gallinago

Wood Sandpiper (Tringa glareola) Science Article 2 abstract Waders generally follow two alternative strategies.The ‘B-strategy’ or ‘energy minimization’ strategy is to initiate migration late in the season, start moulting at the breeding grounds and migrate slowly in small steps, whereas the ‘S-strategy’ or ‘time minimization’istomigrateimmediatelyaftertheendofthebreedingperiodandmoulton the wintering grounds after a migration with only a few […]

Trap response of Wood Sandpipers Tringa glareola.

Wood Sandpiper (Tringa glareola) Science Article 3 abstract We used sightings and recaptures of colour-markedWood Sandpipers to examine the trapresponse of this locally abundant migrant in north-east Austria. Birds were caught in selectedwastewater pools of the local sugar factory using walk-in traps. According toresightings and recaptures, most birds apparently left the initial trapping site soon […]

Breeding Woodcock Scolopax rusticolamonitoring in France

Woodcock (Scolopax rusticola) Science Article 1 abstract The French breeding Woodcock population has been monitored since 1988, and since 1991, the monitored geographical area has been representative of that population. Monitoring is based on observing roding males, the methodology being random sampling with replacement. The annual results are expressed as a frequency of occurrence. The […]
