Kentish Plover (Charadrius alexandrinus) Science Article 3 abstract Female kentish plovers Charadrius alexandrnus typically desert their broods after the chicks hatch, i.e. 1 4 weeks before the chicks fledge or become independent. In this paper we investigate the costs and benefits of desertion for females. Desertion incurs a cost for females: following desertion chick survival […]

BREEDING BIOLOGY OF A KENTISH PLOVER (CHARADRIUS ALEXANDRINUS) POPULATION IN AN INLAND SALINE LAKE
Kentish Plover (Charadrius alexandrinus) Science Article 8 abstract Breeding biology of Kentish Plover (Charadrius alexandrinus) population in an inlnd saline lake. We studied the breeding. biology of Kentish Plovers in Fuente de Piedra lake (southern Spain) in 1997 and q992. Breeders showed sexual dimorphism in tarsal length and body mass: body mass decreased throughout the […]
Changes in Breeding Population Numbers ofKentish Plover Charadrius alexandrinus atAtanasovsko Lake
Kentish Plover (Charadrius alexandrinus) Science Article 2 abstract Atanasovsko Lake is the most important Kentish Plover breeding site in Bulgaria. 141 pairs nested there in 1978, 252 in 1979 and 238 in 1981. During the following years, numbers decreased sharply due to habitat degradation, reaching 39 pairs in 1993 and 65 in 2000. Detailed studies […]
Nest-site selection and breeding biology of Kentish Plover Charadrius alexandrinus on sandy beaches of the Portuguese west coast.
Kentish Plover (Charadrius alexandrinus) Science Article 1 abstract Aims: The nest-site selection and breeding biology of Kentish Plover Charadrius alexandrinus were studied on sandy beaches of the Portuguese West coast.Methods: Nest-site characteristics were compared with those of random points and between successful and unsuccessful nests. Breeding parameters (timing of laying, nesting success and egg size) […]
Nest fate and vegetation characteristics for Snowy Plover and Killdeer in Colorado, USA
Kentish Plover (Charadrius alexandrinus) Science Article 5 abstract We quantified vegetation characteristics at nest sites of Snowy Plovers (Charadrius alexandrinus) and Killdeers (C. vociferus) in south-eastern Colorado during 1995 to assessinterspecific differences in nesting habitat and determine whether habitat characteristics influenced nest fate. Killdeers nested in areas with significantly more grass, litter, and vegetation within […]
Variations in body condition and egg characteristics of female Kentish Plovers Charadrius alexandrinus
Kentish Plover (Charadrius alexandrinus) Science Article 4 abstract Offspring size is a very important life-history trait that may be affected by maternal effects and environmental conditions. We studied variation in egg size and within-clutch symmetry variation in egg volume in Kentish Plovers Charadrius alexandrinus in southern Spain over six years. Repeatability of egg volume among […]
Ivory Gull (Pagophila eburnea) Distribution in Late Summer and Autumn in Eastern Lancaster Sound and Western Baffin Bay
Ivory Gull (Pagophila eburnea) Science Article 1 abstract Ivory gulls in western Baffin Bay and eastern Lancaster Sound were studied in 1976, 1978 and 1979 using aerial surveys. uring September and October concentrations of hundreds of ivory gulls occurred along glacier fronts on southeast Ellesmere and northeast and southeast Devon islands, and where offal was […]
Capturing Jack Snipe Lymnocryptes minimus with mobile horizontally held nets
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 migration insouthern Argentina
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 […]
Population status of the Common Murre Uria aalge in British Columbia
Guillemot (Uria aalge) Science Article 6 abstract The Common Murre Uria aalge is one of the most abundant breeding seabirds in the northern hemisphere (Ainley et al. 2002). The species has a rather disjointed breeding distribution along the Pacific coast of North America: hundreds of thousands of individuals breed on colonies in Oregon and northern […]
