Seasonal and diurnal patterns of singing and song-flight activity in bluethroats (Luscinia svecica)

Bluethroat (Luscinia svecica) Science Article 6 abstract To assess the functions of male song in Bluethroat (Luscinia svecica svecica), seasonal and diurnal patterns of song and song-flight activity were analyzed by using data on individually marked birds. The seasonal patterns of singing and song-flight activity were found to peak shortly after male arrival and before […]

Amplified fragment length polymorphism (AFLP) markersreveal extra-pair parentage in a bird species: the bluethroat(Luscinia svecica)

Bluethroat (Luscinia svecica) Science Article 15 abstract We tested the use of amplified fragment length polymorphism (AFLP) to assess the frequencyof extra-pair parentage in a bluethroat (Luscinia svecica namnetum) population.Thirty-six families totalling 162 nestlings were analysed. Using a combination of threeprimer pairs, we reached an exclusion probability of 93% for the population. S. QUESTIAU, M.C. […]

Wintering and migration of Bluethroat Luscinia svecica in central Spain

Bluethroat (Luscinia svecica) Science Article 2 abstract Aims: Birds have been able to change their breeding and wintering areas by tracking variation in different conditions. In the last decades, the winter distribution of the Bluethroat had been changing. This passerine winters mainly in Africa, although observations of birds wintering in Iberia have increased since the […]

Senior and junior nestlings in asynchronous bluethroat broods differ in their effectiveness of begging

Bluethroat (Luscinia svecica) Science Article 4 abstract In accordance with theoretical models of begging as an honest signal, empirical studies have found that begging by nestlings reflects need and that parent birds respond to variation in begging activity. However, parent birds hatch their broods asynchronously and the resulting within-brood size-asymmetries might induce differences in the […]

Intraspecific variation in sperm length in two passerine species, the Bluethroat Luscinia svecica and the Willow Warbler Phylloscopus trochilus.

Bluethroat (Luscinia svecica) Science Article 10 abstract Sperm cells are highly diversified in birds and considerable research effort has focused on variation in sperm morphology between species. However, surprisingly little is known about intraspecific variation in sperm morphology in birds. We analyzed between- and within-male variation in total sperm length in two passerine species, the […]

Male characteristics and fertilisation success in bluethroats.

Bluethroat (Luscinia svecica) Science Article 7 abstract Extra-pair copulations (EPCs) can create or intensify sexual selection and, provided that fertilisation success is related to phenotypic traits, help explain sexual dimorphism in socially monogamous species. Previous experimental manipulations of the ornamental coloration in male bluethroats, Luscinia s. svecica, have shown effects on their social mating success, […]

Phenology,duration and site fidelity of wintering bluethroat (Luscinia svecica) at Eilat, Israel

Bluethroat (Luscinia svecica) Science Article 14 abstract Between 1984 and 2002,a total of 7643 Bluethroats were ringed and 1054 of these were recaptured at the International Birding and Research Center (IBRCE) in Eilat,Israel (29 33 N, 34 57 E).

Ultraviolet colour vision and ornamentationin bluethroats

Bluethroat (Luscinia svecica) Science Article 18 abstract Many birds see in the ultraviolet (300^400 nm), but there is limited evidence for colour communication (signalling by spectral shape independently of brightness) in this hidden’ waveband. Such data are critical for the understanding of extravagant plumage colours STAFFAN ANDERSSON AND TROND AMUNDSEN, Proc. R. Soc. Lond. B […]
