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 […]

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)

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 […]

Jack Snipe (Lymnocryptes minimus) Science Article 1 abstract The biology of the Jack Snipe Lymnocryptes minimus is poorly known and recent estimates of its population size are contradictory. To encourage ringing and marking studies of this cryptic species, we tested and improved a trapping technique in the Camargue during winter and migration periods. This capture […]

Hudsonian Godwit (Limosa haemastica) Science Article 1 abstract Among all animals, the Hudsonian Godwit Limosa haemastica is one of the champion migrants. In spite of this recognition, or perhaps because of it, there is little understanding of how this northern-nesting bird completes its migrations between arctic breeding areas ofCanada and Alaska, and its winter habitats […]

Greater Yellowlegs (Tringa melanoleuca) Science Article 1 abstract The possible relationship between trematode infestation and over-summering was explored in Greater Yellowlegs (ninga melanoleuca). Birds were collected throughout the year in coastal Venezuela to examine seasonal and age-related variation in digenean trematode infestations. Yellowlegs were infested with eleven digenean genera. Only four genera were common to […]

Great Knot (Calidris tenuirostris) Science Article 1 abstract Since the early 1960s it has been held that migrating birds deposit and use only fat as fuel during migratory flight, with the non-fat portion of the body remaining homeostatic. Recent evidence from

Eskimo Curlew (Numenius borealis) Science Article 1 abstract From the shores of the Arctic Ocean, Where they breed, to Patagonia, where they probably Winter (Ibis, 1878, page 404), is a journey of seven thousand miles; yet the Eskimo CurleWs, familiarly known as Doughbirds, compass it every year on their migrations.

Dunlin (Calidris alpina) Science Article 12 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 of […]

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 […]
