Chaffinch (Fringilla coelebs) Science Article 3 abstract Numbers of many bird species which breed on farmland, and are reliant oncropped land for feeding or nesting, declined between the 1960s and 1990s. Incontrast, Chaffinch Fringilla coelebs numbers increased on farmland over thesame period. This study investigates the influence of both cropped and noncroppedland on Chaffinches foraging […]

Structural conservation and variation in the mitochondrial control region of fringilline finches (Fringilla spp.) and the greenfinch (Carduelis chloris
Chaffinch (Fringilla coelebs) Science Article 2 abstract We sequenced the entire control region and portions of flanking genes (tRNAPhe, tRNAGiu, and ND6) in the common chaffinch (Fringilla coelebs), blue chaffinch (F. teydea), brambling (F. montifringilla), and greenfinch (Carduelis chloris). In these finches the control region is similar in length (1,223-1,237 bp) and has the same […]
Some aspects of Chaffinch Fringilla coelebs biology, based on an analysis of individuals ringed during 1991 to 2003 in Norfolk, England
Chaffinch (Fringilla coelebs) Science Article 1 abstract From 1991 to 2003, 2,954 Chaffinches Fringilla coelebs were caught and ringed, year-round, at Hilborough, Norfolk, England. The age and sex composition of Chaffinches varied between winters, but no systematic pattern was apparent. The age and sex composition of Chaffinches caught during winter did not vary significantly from […]
Time in captivity, individual differences and foragingbehaviour in wild-caught chaffinches
Chaffinch (Fringilla coelebs) Science Article 4 abstract Wild-caught animals are often given a settling in period before experimental trials are initiated.We used wild-caught chaffinches (Fringilla coelebs) to investigate (a) the effect ofsettling in period duration on the likelihood that chaffinches foraged during experimental trialsand (b) whether settling in period duration influenced measures of foraging and […]
Structural conservation and variation in the mitochondrial control region of fringilline finches (Fringilla spp.) and the greenfinch (Carduelis chloris

Abundance of owls and Bramblings Fringilla montifringilla inrelation to mast seeding in south-eastern Sweden
Brambling (Fringilla montifringilla) Science Article 2 abstract We investigated the relationship between mast seeding in beech Fagus sylvaticus and oak Quercus spp., and the occurrence of the rodent-dependent predators Tengmalm’s Owl aegolius funereus, Long-eared Owl Asio otus and Tawny Owl Strix aluco in south-eastern Sweden (Blekinge) 1992-2000. We also compared available data on seed production […]
Biometrics, ageing, sexing and moult of the Blue Chaffinch Fringilla teydea teydea on Tenerife (Canary Islands)
Blue Chaffinch (Fringilla teydea) Science Article 1 abstract The Blue Chaffinch Fringilla teydea is one of a few Palearctic species for which biometric data are lacking from the field; we address this issue here. Blue Chaffinches were caught by mist net, at ten sites on Tenerife (Canary Islands), and measured. Data on biometrics and moult […]
Density estimates, microhabitat selection and foraging behaviour of the endemic Blue Chaffinch Fringilla teydea teydea on Tenerife (Canary Islands)
Blue Chaffinch (Fringilla teydea) Science Article 2 abstract Point counts were used for censusing birds. Data were analysed with the DISTANCE software programs using an average detectability function. Microhabitat structure was characterized by measuring 11 variables in a 25m radius at each point. We used Poisson regression models to predict counts for Blue Chaffinch from […]
