Rock Partridge (Alectoris graeca) Science Article 4 abstract The rock partridge (Alectoris graeca) is distributed in the Alps, Apennines and Balkans, in mountainous areas that were heavily affected by cyclic climate and landscape changes during the last Pleistocene glaciations. Some partridge populations have colonized and expanded their present ranges only after deglaciation and recent deforestation […]

Sex- and age-related variation in plasma carotenoids despite a constant diet in the Red-legged Partridge Alectoris rufa
Red-legged Partridge (Alectoris rufa) Science Article 2 abstract We studied seasonal variation in plasma carotenoid levels of captive Redlegged Partridges Alectoris rufa in relation to sex, age and condition. The legs, bill and eye lores in this species are bright red due to carotenoid pigments. Carotenoid levels in the plasma varied significantly among sampling periods. […]
Effects of Housing Type and Breeding System on the Reproductive Capacity of the Red-Legged Partridge (Alectoris rufa)
Red-legged Partridge (Alectoris rufa) Science Article 1 abstract Current methods of intensive breeding of the red-legged partridge (Alectoris rufa) are based on ‘industrial’ laying practices, including removal and artificial incubation of eggs. These procedures can alter the reproductive behavior and physiology of the birds and, therefore, may not be suitable for use in breeding programs […]
CAUSES AND CONSEQUENCES OF INGESTED LEAD PELLETS IN CHUKARS
Red-legged Partridge (Alectoris rufa) Science Article 4 abstract Lead-pellet ingestion andthe resulting toxicosis are well-documented in waterfowl,raptors, and Mourning Doves (Zenaidamacroura) (Kendall et al. 1996).

Open-habitat birds in recently burned areas: the role of the fire extent and species’ habitat breadth
Red-legged Partridge (Alectoris rufa) Science Article 3 abstract Single burned areas contained 0 to 15 open-habitat species (mean = 7.6), and in all the areas combined there were 22 species, including 17 with an unfavourable conservation status in Europe. The most frequent were Carduelis cannabina, Lullula arborea, Alectoris rufa, Oenanthe hispanica and Emberiza cia, but […]
Fluctuations related to rainfall in richness and abundance of birds of steppic Mediterranean habitats
Quail (Coturnix coturnix) Science Article 6 abstract The existence of interannual variations in the richness and abundance of bird species breeding in pseudo-steppic Mediterranean areas is analysed and related to the important fluctuations that take place in rainfall, which in turn deeply influence vegetation growth. The hypothesis of food limitation as a key factor in […]
Kinematics and mechanics of ground take-off in the starling Sturnis vulgaris and the quail Coturnix coturnix .
Quail (Coturnix coturnix) Science Article 3 abstract The mechanics of avian take-off are central to hypotheses about flight evolution, but have not been quantified in terms of whole-body movements for any species. In this study, I use a combination of high-speed video analysis and force plate recording to measure the kinematics and mechanics of ground […]
African climate warming advances spring arrival of the Common Quail Coturnix coturnix
Quail (Coturnix coturnix) Science Article 5 abstract The Common Quail is one of the most popular steppe-land birds and is also one of greateconomic interest. Despite this, some aspects of its life cycle remain unclear, especially those concerned with the wintering phase. Here we report a long-term study of the spring arrival phenology of this […]
Observations on the cloacal gland of the eurasian quail, Coturnix coturnix
Quail (Coturnix coturnix) Science Article 1 abstract While handling the Eurasian quail, Coturnix coturnix, in a game stocking program, the junior author noted that the breeding males issued a frothy fluid from their cloac . Upon examination we noted that this secretion originated in a gland located above the dorsal lip of the cloaca. There […]
Comparison of migratory tendency in European Quail Coturnix c. coturnix, domestic Japanese Quail Coturnix c. japonica and their hybrids
Quail (Coturnix coturnix) Science Article 4 abstract Since the 1970s, the decline of the occidental populations of European Quail Coturnix c. coturnix, a partial migrant Galliform species, has driven the release of domestic Japanese Quail Coturnix c. japonica into the wild as game birds. Recent experiments suggest that reproductive isolating mechanisms have not developed to […]
