Víctor Martín-Vélez, Auteur ; Julián Cano-Povedano, Auteur ; Belén Cañuelo-Jurado, Auteur ; Cosme López-Calderón, Auteur ; Vanessa Céspedes, Auteur ; Macarena Ros, Auteur ; Marta I. Sanchez, Auteur ; Judy Shamoun-Baranes, Auteur ; Wendt Muller, Auteur ; Chris B. Thaxter, Auteur ; Cornelis J. Camphuysen, Auteur ; Andrés Cózar, Auteur ; Andy J. Green, AuteurGeneral context Gulls ingest plastic and other litter while foraging in open landfills, because organic matter is mixed with other debris. Therefore, gulls are potential biovectors of plastic pollution into natural habitats, especially when the[...]
Article
Kees (C J.) Camphuysen, Auteur ; Susanne C. van Donk, Auteur ; Judy Shamoun-Baranes, Auteur ; Rosemarie Kentie, AuteurThe population increase of Lesser Black-backed Gulls in The Netherlands triggered investigations into life-history, migratory movements and foraging ecology during 16 years of nest-monitoring, colour-ringing and GPS-tracking on the island of Tex[...]
Article
Rosemarie Kentie, Auteur ; Judy Shamoun-Baranes, Auteur ; Arie L. Spaans, Auteur ; Kees (C. J.) Camphuysen, AuteurDemographic rates such as recruitment and survival probability can vary considerably among populations of the same species due to variation in underlying environmental processes. If environmental processes are spatially correlated, nearby popula[...]

Jan van der Winden, Auteur ; Niels Hogeweg, Auteur ; Edwin Baaij, Auteur ; Peter W. van Horssen, Auteur ; Judy Shamoun-Baranes, Auteur ; René Vos, Auteur ; Theunis Piersma, AuteurCapsule Migration studies of tagged Eurasian Bitterns Botaurus stellaris provide information on the behaviour of this secretive species in relation to weather conditions.Aims To study if cold spells trigger southward migration in resident Eurasi[...]
Article
Jan van der Winden, Auteur ; Niels Hogeweg, Auteur ; Judy Shamoun-Baranes, Auteur ; Theunis Piersma, AuteurIn many bird species intraspecific variation in migration strategies is related to sex or size. The Eurasian Bittern Botaurus stellaris is a sexually size-dimorphic heron species with a vast breeding and wintering range spanning a range of clima[...]
Article
Peter Rock, Auteur ; C.j. Camphuysen, Auteur ; Judy Shamoun-Baranes, Auteur ; Viola H. Ross-Smith, Auteur ; Ian P. Vaughan, AuteurRecent developments in GPS tracking technology allow the movements of bird species to be followed in ever-greater detail. Seabird research is benefiting greatly, due to the challenges of tracking species that often roam widely out at sea. Amongs[...]
Article
Michael U. Kemp, Auteur ; Judy Shamoun-Baranes, Auteur ; Hans van Gasteren, Auteur ; Willem Bouten, Auteur ; E. Emiel van Loon, AuteurA bird's ground speed is influenced by the wind conditions it encounters. Wind conditions, although variable, are not entirely random. Instead, wind exhibits persistent spatial and temporal dynamics described by the general circulation of the at[...]
Article
James D. McLaren, Auteur ; Judy Shamoun-Baranes, Auteur ; C. J. Camphuysen, Auteur ; Willem Bouten, AuteurBirds in flight are proposed to adjust their body orientation (heading) and airspeed to wind conditions adaptively according to time and energy constraints. Airspeeds in goal-directed flight are predicted to approach or exceed maximum-range airs[...]
Article
Wouter M. G. Vansteelant, Auteur ; Brecht Verhelst, Auteur ; Judy Shamoun-Baranes, Auteur ; Willem Bouten, Auteur ; E. Emiel van Loon, Auteur ; Keith L. Bildstein, AuteurEvery autumn, large numbers of raptors migrate through geographical convergence zones to avoid crossing large bodies of water. At coastal convergence zones, raptors may aggregate along coastlines because of convective or wind conditions. However[...]
Article
Hans van Gasteren, Auteur ; Iwan Holleman, Auteur ; Willem Bouten, Auteur ; Emiel van Loon, Auteur ; Judy Shamoun-Baranes, AuteurAlthough radar has been used in studies of bird migration for 60 years, there is still no network in Europe for comprehensive monitoring of bird migration. Europe has a dense network of military air surveillance radars but most systems are not d[...]
Article
Willem Bouten, Auteur ; Edwin W. Baaij, Auteur ; Judy Shamoun-Baranes, Auteur ; Kees C. J. Camphuysen, AuteurTracking devices and bio-loggers provide crucial information on the ecology and behaviour of birds in their natural environment. An optimal tracking system should be lightweight, measure three-dimensional locations, enable flexible measurement s[...]
Article
Kees Camphuysen, Auteur ; Judy Shamoun-Baranes, Auteur ; Willem Bouten, Auteur ; Stefan Garthe, AuteurThe identification of marine areas of importance for seabirds is a challenge, because it is often unclear how birds are using the different areas in which they occur. Species differ in habitat choice, foraging behaviour and feeding range, but al[...]
Article
Michael U. Kemp, Auteur ; Judy Shamoun-Baranes, Auteur ; Adriaan M. Dokter, Auteur ; Emiel van Loon, Auteur ; Willem Bouten, AuteurBy altering its flight altitude, a bird can change the atmospheric conditions it experiences during migration. Although many factors may influence a bird's choice of altitude, wind is generally accepted as being the most influential. However, th[...]

Viola H. Ross-Smith, Auteur ; Chris B. Thaxter, Auteur ; Elizabeth A. Masden, Auteur ; Judy Shamoun-Baranes, Auteur ; Niall H. K. Burton, Auteur ; Lucy J. Wright, Auteur ; Mark M. Rehfisch, Auteur ; Alison Johnston, AuteurWind energy generation is increasing globally, and associated environmental impacts must be considered. The risk of seabirds colliding with offshore wind turbines is influenced by flight height, and flight height data usually come from observers[...]
Article
Hans van Gasteren, Auteur ; Inge Both, Auteur ; Judy Shamoun-Baranes, Auteur ; Jacques-Olivier Laloe, Auteur ; Willem Bouten, AuteurThe presence of birds at and near airfields is a constant problem for flight safety all around the world. To minimize the risk of bird strikes, airfields practice wildlife management policies, including habitat modification and bird scaring tech[...]
Article
Judy Shamoun-Baranes, Auteur ; Willem Bouten, Auteur ; Cornelis Jan Camphuysen, Auteur ; Edwin Baaij, AuteurAdult Lesser Black-backed Gulls Larus fuscus were followed during the breeding season using a high-resolution GPS tracking system. Little is known about the foraging movements of these birds and what they do when they are away from the colony. T[...]
Article
Judy Shamoun-Baranes, Auteur ; Joseph B. Burant, Auteur ; E. Emiel van Loon, Auteur ; Willem Bouten, Auteur ; C. J. Camphuysen, AuteurMigration strategies differ greatly among and within avian populations. The associated trade-offs and fitness consequences of diverse strategies and how they persist are pertinent questions in migration research. Migration is a costly endeavour,[...]
Article
Wouter M. G. Vansteelant, Auteur ; Judy Shamoun-Baranes, Auteur ; James McLaren, Auteur ; Jan van Diermen, Auteur ; Willem Bouten, AuteurThermal soaring birds reduce flight-energy costs by alternatingly gaining altitude in thermals and gliding across the earth's surface. To find out how soaring migrants adjust their flight behaviour to dynamic atmospheric conditions across entire[...]
