PARENTAL ROLES AND THE MATING SYSTEM OF THE LONG-TOED STINT CALIDRIS SUBMINUTA

Long-toed Stint (Calidris subminuta) Science Article 2 abstract The mating system of the Long-toed Stint is poorly known. Observations of several broods in western Kamchatka in 1989 suggest a monogamous mating system in which incubation is shared, but with males caring for the brood after hatching Pavel S. Tomkovich, WSG Bull. 57: 42-43. Download article […]

First record of a long-toed stint (Calidris subminuta) in New Zealand

Long-toed Stint (Calidris subminuta) Science Article 1 abstract On 31 August 1997 Sheila Petch and Nick Allen were at Jarvis Road, Lake Ellesmere looking for shorebirds newly arrived from the Northern Hemisphere. While looking at a flock of recently arrived red-necked stints (Calidris ruflcollis) they noticed a bird of similar size, but with pale legs […]

LONGEVITY RECORD FOR THE LEAST SANDPIPER: A REVISION

Least Sandpiper (Calidris minutilla) Science Article 2 abstract A male Least Sandpiper (Calidris minutilla) bred at 16+ yr of age, not 17+ as previously reported (Miller and Reid, J. Field Ornithol.5 8:49-51, 1987). Extensive European banding programs have revealed much older scolopacids. E. H. MILLER, J. Field Ornithol., 59(4):403-404 Download article download full text (pdf)

Functional association of bill morphology and foragingbehaviour in calidrid sandpipers

Least Sandpiper (Calidris minutilla) Science Article 4 abstract Foraging behaviour in birds co-varies with bill morphology. Shorebirds exhibit pronouncedinter- and intra-specific variation in bill length and shape as well as in foraging behaviour.Pecking, or feeding on epifaunal intertidal invertebrates, is associated with a straight bill, while probing,feeding on infaunal prey S. NEBEL et al, University […]

The Influence of Body Condition on the Stopover Ecology of LeastSandpipers in the Lower Mississippi Alluvial Valley during FallMigration

Least Sandpiper (Calidris minutilla) Science Article 3 abstract Many shorebirds are long-distance migrants and depend on the energy gained at stopoversites to complete migration. Competing hypotheses have described strategies used by migrating birds; the energy-selection hypothesis predicts that shorebirds attempt to maximize energy gained at stopover sites, whereas the time-selection hypothesis predicts that shorebirds attempt […]

Latitudinal clines in sex ratio, bill, and wing lengthin Least Sandpipers

Least Sandpiper (Calidris minutilla) Science Article 1 abstract Differential distribution of nonbreeding Least Sandpipers (Calidris minutilla) according to sex,bill, and wing length was documented using capture data from six locations between California and Ecuador. Thedistribution of age classes did not vary with latitude. Females, which are slightly larger than males, migrated furthersouth. Wing length increased […]

Mitochondrial Control-Region Sequences in Two Shorebird Species, the Turnstone and the Dunlin, and Their Utility in Population Genetic Studies

Dunlin (Calidris alpina) Science Article 2 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 constructing […]
