Article
Emma Blackburn, Auteur ; Malcolm Burgess, Auteur ; Benedictus Freeman, Auteur ; Alice Risely, Auteur ; Arin Izang, Auteur ; Sam Ivande, Auteur ; Chris Hewson, Auteur ; Will Cresswell, AuteurCapsule: There is a substantial gain in precision and accuracy of geolocator locations when using a light stalk.Aims: Light stalks or tubes increase the accuracy of geolocators when tracking migrant birds because they reduce potential shading of[...]
Article
Emma Blackburn, Auteur ; Malcolm Burgess, Auteur ; Benedictus Freeman, Auteur ; Alice Risely, Auteur ; Arin Izang, Auteur ; Sam Ivande, Auteur ; Chris Hewson, Auteur ; Will Cresswell, AuteurThe flexibility for migrant land birds to be able to travel long distances rapidly without stopovers, and thus to cross wide inhospitable areas such as deserts and oceans, is likely to be a major determinant of their survival during migration. W[...]

Emma Blackburn, Auteur ; Malcolm Burgess, Auteur ; Benedictus Freeman, Auteur ; Alice Risely, Auteur ; Arin Izang, Auteur ; Sam Ivande, Auteur ; Chris Hewson, Auteur ; Will Cresswell, AuteurDans Ibis (159(4) 2017)The spatial scale of non-breeding areas used by long-distance migrant animals can vary from specific, relatively small non-breeding areas for each independent breeding population (high connectivity) to a distribution over a large non-breeding ar[...]
Article
Alice Risely, Auteur ; Emma Blackburn, Auteur ; Will Cresswell, AuteurAfro-Palaearctic migrants are declining to a greater degree than other European species, suggesting that processes occurring in Africa or on migration may be driving these trends. Constraints on food availability on the wintering grounds may con[...]
Article
Emma Blackburn, Auteur ; Will Cresswell, AuteurWintering Northern Wheatears Oenanthe oenanthe in the Sahel region of Northern Nigeria held small (approximately 70 m diameter) distinct territories during the study period, and territory size did not differ between adult and first winter birds.[...]
Article
Emma Blackburn, Auteur ; Will Cresswell, AuteurThe decision for a migratory animal to be site faithful in its non-breeding season has profound implications for migratory connectivity, resilience to winter habitat loss and population dynamics through carry-over effects on future breeding succ[...]
Article
Emma Blackburn, Auteur ; Will Cresswell, AuteurFor migratory birds, it is necessary to estimate annual and overwinter survival rates, identify factors that influence survival, and assess whether survival varies with age and sex if we are to understand population dynamics and thus inform cons[...]

Article
Marina Xenophontos, Auteur ; Emma Blackburn, Auteur ; Will Cresswell, AuteurLong-distance migratory flights with multiple stop-overs, multiple wintering sites, and small-scale connectivity in Afro-Palearctic migrants are likely to increase their vulnerability to environmental change and lead to declining populations. He[...]
Article
Emma Blackburn, Auteur ; Malcolm Burgess, Auteur ; Benedictus Freeman, Auteur ; Alice Risely, Auteur ; Arin Izang, Auteur ; Sam Ivande, Auteur ; Chris Hewson, Auteur ; Will Cresswell, AuteurData from location logging tags have revolutionised our understanding of migration ecology, but methods of tagging that do not compromise survival need to be identified. We compared resighting rates for 156 geolocator-tagged and 316 colour ringe[...]
Article
Emma Blackburn, Auteur ; Will Cresswell, AuteurFor migrant birds, which habitats are suitable during the non-breeding season influences habitat availability, population resilience to habitat loss, and ultimately survival. Consequently, habitat preferences during winter and whether habitat se[...]
