Least Tern (Sternula antillarum) Science Article 1 abstract Local populations of the endangered interior least tern (Sterna antillarum) nestwithin riverine and alkaline flat habitats of the central United States. We summarizedestimates of survival for egg, chick, fledgling, subadult (
NOCTURNAL PREDATIONOF CALIFORNIA LEAST TERNS AT A SOUTHERN CALIFORNIA LEAST TERN
Least Tern (Sternula antillarum) Science Article 5 abstract Predation is difficult to observe and quantification of impacts have consequentlybeen difficult, especially for predators active at night. Using night-capable camerasplaced throughout a California least tern (Sternula antillarum browni) colony I examinedrates of predation by a complex of potential predators. I identified and quantified directand indirect effects […]
Evidence for Reproductive Mixing of Least Tern Populations
Least Tern (Sternula antillarum) Science Article 4 abstract The Atlantic race of the Least Tern (Sterna antillarum antillarum) breeds along the coastal beaches and bay systems of the Atlantic Ocean and Gulf of Mexico from Maine to southern Texas, while the Interior Least Tern (S. a. athalassos) breeds in the interior of the United States […]
Genetic Variation among Subspecies of Least Tern(Sterna antillarum): Implications for Conservation
Least Tern (Sternula antillarum) Science Article 2 abstract DNA sequence variation from two nuclear introns and part of the mitochondrial cytochromebgenewere used to evaluate population structure among three subspecies of Least Tern that nest in the United States (California[Sterna antillarum browni], Interior [S. a. athalassos], Eastern [S. a. antillarum]). Sequence variation was highestfor nuclear intron […]
REPRODUCTIVE SUCCESS OF THE INTERIOR LEAST TERN(STERNA ANTILLARUM) IN RELATION TO HYDROLOGY ON THELOWER MISSISSIPPI RIVER
Least Tern (Sternula antillarum) Science Article 3 abstract The annual hydrograph of large rivers, including flood pulses and low-flow periods, is believed to play a primary rolein the productivity of biota associated with these ecosystems. We investigated the relationship between riverhydrology and Interior least tern (Sterna antillarum) reproductive success on the Lower Mississippi River from […]
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 […]
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)
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 […]
Evidence of prenuptial moult in the Little BitternIxobrychus minutus
Least Bittern (Ixobrychus exilis) Science Article 4 abstract Evidence for a partial prenuptial moult in the Little Bittern Ixobrychus minutus is reported for the firsttime, and is based on both live and museum specimens. The prenuptial moult, which is probablyundertaken in the African winter quarters shortly before the spring migration, involves body feathersand often some […]
