Garden Warbler (Sylvia borin) Science Article 2 abstract During spring and autumn migration 2003, the Swiss Ornithological Institute set up a concerted project in Mauritania to study bird migration across the Sahara. I participated with a side project using artificial induction of landfall with sound luring in an attempt to overcome the potential problem of […]

Territory characteristics and coexistence with heterospecificsin the Dartford warbler Sylvia undata acrossa habitat gradient
Dartford Warbler (Sylvia undata) Science Article 2 abstract The study of successional gradients may help to understand the relative influence of habitat structure and competition on territory characteristics. Here, we evaluate the effects of vegetation cover, conspecific and heterospecific densities Pere Pons et al, Behav Ecol Sociobiol (2008) 62:1217-1228 Download article download full text (pdf)
Habitat type determines the effects of disturbance on the breeding productivity of the Dartford Warbler Sylvia undata
Dartford Warbler (Sylvia undata) Science Article 1 abstract Numerous studies have examined the causes and impacts of human disturbance on birds, but little is known about how these impacts vary among habitats. This is of applied importance both for predicting bird responses to changes in disturbance and in planning how to reduce disturbance impacts. The […]
Habitat and nest site preferences of Sylvia atricapilla and S. melanocephala in Majorca
Blackcap (Sylvia atricapilla) Science Article 3 abstract Sylvia melanocephala (S. m.) and S. atricapilla (S. a.) are common in woody habitats of the western Mediterranean. Nevertheless, detailed information on habitat and particularly nest site preferences is scarce. Within its western Pal arctic distribution, S. m. breeds in the Mediterranean zone, mainly in dry coastal regions […]
Signals of profitability? Food colour preferences in migrating juvenile blackcaps differ for fruits and insects.
Blackcap (Sylvia atricapilla) Science Article 5 abstract Red is a common colour signal in both aposematic warning displays, and in fruit displays. One common feature is that red is conspicuous against the natural background of the prey and fruits. However, there is a potential conflict between fruits and aposematic prey in how a bird predator […]
The breeding performance of Blackcap Sylvia atricapilla in two types of forest habitat.
Blackcap (Sylvia atricapilla) Science Article 1 abstract The breeding densi ty of Blackcap was about four times higher in deciduous (D) riparian linear vegetation than in mixed (M) coniferous woodlots in the farmland of Eastern Bohemia, Czech Republi c, over two years. Laying started and peaked about two days later in M habitat, possibly because […]
HISTORICAL DIVERSIFICATION OF MIGRATION PATTERNS IN A PASSERINE BIRD
Blackcap (Sylvia atricapilla) Science Article 11 abstract Migratory strategies of birds require complex orientation mechanisms, morphological adaptations, and lifehistory adjustments. From an evolutionary perspective, it is important to know how fast this complex combination of traits can evolve. We analyzed mitochondrial control-region DNA sequences in 241 blackcaps (Sylvia atricapilla) JAVIER PEREZ-TRIS, Evolution, 58(8), 2004, pp. […]
Are blackcaps Sylvia atricapilla differential distance migrants by sex?
Blackcap (Sylvia atricapilla) Science Article 7 abstract The extent of movements of male and female British blackcaps were analysed using ringing recovery records. Furthermore, through a literature review and the collection of original field data, the sex-ratios of blackcap samples taken at several latitudes in Europe and Africa were compared. Paulo CATRY, Miguel LECOQ, Greg […]
Is there an autumn migration of continental Blackcaps(Sylvia atricapilla) into northern Europe?
Blackcap (Sylvia atricapilla) Science Article 10 abstract All ringing recovencs of Blackcaps in Europe were examined during Northward autumn migration into this area. The result indicates autumn movements… Thimi Fransson and Bengt-Olov Stolt, Vogelwarte 37: 89-95 Download article download full text (pdf)
