Citril Finch (Serinus citrinella) Science Article 1 abstract Ants have been reported as the direct or indirect cause for nest loss in a few bird species. Here we describe a possible instance affecting a Citril Finch Serinus citrinella nest in the Spanish Pre-Pyrenees. The nest was found on 18 may 2002, when building activity was […]
Biometrics of Citril Finch Serinus citrinella in the west Pyrenees and the influence of feather abrasion on biometric data
Citril Finch (Serinus citrinella) Science Article 2 abstract Biometric data are an essential component of studies into the breeding biology of bird populations. Citril Finches Serinus citrinella in the Pyrenees mainly feed on pine seeds, and coniferous habitats in the west Pyrenees are of significant conservation importance. The aim of this study was to increase […]
Sexual differences in levels of blood carotenoids in Cirl Buntings Emberiza cirlus.
Cirl Bunting (Emberiza cirlus) Science Article 1 abstract Carotenoids are responsible for the bright red and yellow plumage of birds. These substances cannot be synthesised by birds and must be obtained from the diet and transported through the blood to the feathers. The carotenoid content of blood was measured in Cirl Buntings Emberiza cirlus, a […]
A Black Vulture aegypius monachus from Roman Valkenburg The Netherlands
Cinereous Vulture (aegypius monachus) Science Article 1 abstract The former occurrence of aegypius monachus in The Netherlands is attested by a bill fragment from the Roman period excavation at Valkenburg (South-Holland). The plausibility of the occurrence of this species in the Dutch prehistoric landscape and in the cultural context of the Roman settlement will be […]
THE NEST AND EGGS OF THE CINEREOUS MOURNER(LANIOCERA HYPOPYRRA)
Cinereous Mourner (Laniocera hypopyrra) Science Article 1 abstract We present the first account of nesting biology for the Neotropical suboscine genus Lanioceraby describing the nest and eggs of the Cinereous Mourner (L. hypopyrra) based on observations made in thePeruvian Amazon during 2001. The cup-shaped nest was in mature floodplain forest among the branches of anepiphytic […]
Known and predicted African winter distributions and habitat useof the endangered Basra reed warbler (Acrocephalus griseldis)and the near-threatened cinereous bunting (Emberiza cineracea)
Cinereous Bunting (Emberiza cineracea) Science Article 1 abstract The Basra reed warbler (Acrocephalus griseldis) and the cinereous bunting (Emberiza cineracea) are the only two Western Palearctic passerine bird species that overwinter in East Africa and are classified by BirdLife International as endangered and near-threatened, respectively. To refine the African wintering ranges of these two species, […]
Effects of temperature and altitude on ventilationand gas exchange in chukars (Alectoris chukar)
Chukar Partridge (Alectoris chukar) Science Article 9 abstract The effects of ambient temperature (T,)on ventilation and gas exchange in chukar partridges(Alectoris chukar) were determined after acclimationto low and high altitude (LA and HA;340 and 3,800 m, respectively). Mark A. Chappell and Theresa L. Bucher, J Comp Physiol B (1987) 157:129-136 Journal Download article download full […]
Lack of genetic structure of Cypriot Alectoris chukar (Aves, Galliformes) populations asinferred from mtDNA sequencing data
Chukar Partridge (Alectoris chukar) Science Article 4 abstract The Chukar (Alectoris chukar cypriotes) is the most common game bird in Cyprus. Since 1990 the Cypriot Government has established a restocking program with captive
GENETIC STRUCTURE OF CHUKAR (ALECTORIS CHUKAR) POPULATIONS IN ISRaeL
Chukar Partridge (Alectoris chukar) Science Article 1 abstract We used multilocus proteine lectrophoresis to analyze population genetics of Chukars collected at five locations along a north-south gradient in Israel. These birds belongedto two nominal subspecies, the northern A. c. cypriotes, and southern A. c. sinaica.Chukars from China were used as an outgroup. ETTORE RANDI, The […]
Relationship between heterozygosity and asymmetry: a test across the distribution range
Chukar Partridge (Alectoris chukar) Science Article 5 abstract The genetic basis of developmental stability, as measured by bilateral asymmetry, has been debatedfor over 50 years among developmental and evolutionary biologists. One of the central theoriesdealing with this relationship suggests that higher levels of genetic diversity, as re
