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 […]

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 […]

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 […]

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) […]

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 […]

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 […]

Kentish Plover (Charadrius alexandrinus) Science Article 7 abstract Population size, distribution and reproductive success of Kentish Plovers in Hungary are sum-marised. 105-140 pairs bred in 1988-1992. Two breeding sites (Miklapuszta and Southern Hun-gary) contained the bulk of the population, with 60-80 pairs and 35-40 pairs, respectively. Thenumber of breeding pairs has declined in recent years. […]

Kentish Plover (Charadrius alexandrinus) Science Article 6 abstract Kentish Plover Charadrius alexandrinus pairs generally re-nest together after the loss of a clutch. In contrast, two females who hatched clutches changed mates before re-nesting, thus proving sequential polyandry. Observations of adults accompanying broods show that females normally desert the brood about a week after hatching. The […]
