Clewley, Auteur ; Emily Scragg, Auteur ; Stephen C. Votier, AuteurDespite urbanization's general erosion of biodiversity, towns and cities provide novel opportunities for some species. During the 20th century, gulls (Laridae) colonized urban areas around the world where they flourished. At the same time, some [...]

Hodgson, Auteur ; Anthony David Fox, AuteurDans Ibis (164(2) 2022)Population growth rates in geese can be sensitive to small changes in survival and/or production of young, and understanding which demographic rates explain more variation in population change can be crucial for implementing effective conservati[...]

Fraser Bell, Auteur ; Stuart Bearhop, Auteur ; Martins Briedis, Auteur ; Myriam El Harouchi, Auteur ; Sophie C. Bell, Auteur ; Joan Castello, Auteur ; Malcolm Burgess, AuteurDans Ibis (164(2) 2022)Songbird populations are in decline all over the world, and our understanding of the causal mechanisms remains surprisingly limited. It is important to identify the extent of individual variations in migratory behaviour to better understand spec[...]

Thomas W. Bodey, Auteur ; Russell Barnett, Auteur ; Christopher R. du Feu, Auteur ; John R. Clark, Auteur ; Stuart Bearhop, AuteurDans Ibis (163(1) 2021)Global anthropogenic changes are significantly impacting the ecology and evolution of many species. Among temperate taxa, changes to reproductive phenology as a result of warming springs are apparent. However, how such responses to abiotic chang[...]
Article
Andrea Soriano-Redondo, Auteur ; Jorge S. Gutiérrez, Auteur ; Dave Hodgson, Auteur ; Stuart Bearhop, AuteurBillions of vertebrates migrate to and from their breeding grounds annually, exhibiting astonishing feats of endurance. Many such movements are energetically costly yet there is little consensus on whether or how such costs might influence sched[...]

Thomas W. Bodey, Auteur ; Robbie A. Mcdonald, Auteur ; Rob D. Sheldon, Auteur ; Stuart Bearhop, AuteurThe control of generalist predator populations is increasingly adopted as a management tool to combat declines in ground-nesting bird populations. However, compensatory predation by uncontrolled species frequently occurs, so determining the rela[...]
Article
Richard Inger, Auteur ; Stuart Bearhop, AuteurIn the past 20 years the use of stable isotope analysis has become increasingly common in ecological studies. In fact, in some instances these techniques have yielded remarkable insights into the foraging preferences and migrations of birds. Des[...]

Thomas W. Bodey, Auteur ; Stuart Bearhop, Auteur ; Sugoto S. Roy, Auteur ; Jason Newton, Auteur ; Robbie A. Mcdonald, Auteur1. The detrimental impacts of invasive, non-native species on islands are widely acknowledged and it is often best to act rapidly against such species, even where uncertainty exists over the best way to proceed. If management actions are evaluat[...]

Jaime Resano-Mayor, Auteur ; Antonio Hernández-Matías, Auteur ; Joan Real, Auteur ; Francesc Pares, Auteur ; Richard Inger, Auteur ; Stuart Bearhop, AuteurDiet analyses are central to the study of avian trophic ecology, and stable isotope analyses have made an increasing contribution in the last two decades. Few isotopic studies have assessed the diet of raptor species, which are more frequently a[...]
Article
Richard A. Fuller, Auteur ; Stuart Bearhop, Auteur ; Neil B. Metcalfe, Auteur ; Theunis Piersma, AuteurForaging birds can manage time spent vigilant for predators by forming groups of various sizes. However, group size alone will not always reliably determine the optimal level of vigilance. For example, variation in predation risk or food quality[...]
Article
Stephen A. Oswald, Auteur ; Stuart Bearhop, Auteur ; Robert W. Furness, Auteur ; Brian Huntley, Auteur ; Keith C. Hamer, AuteurBirds such as great skuas Catharacta skua adapted for successful breeding at high latitudes may experience problems of heat dissipation in mild climates. Great skuas spend time bathing at freshwater sites close to breeding territories and here, [...]
Article
Matthew J. Silk, Auteur ; Darren P. Croft, Auteur ; Tom Tregenza, Auteur ; Stuart Bearhop, AuteurAlmost all animal social groups show some form of fission-fusion dynamics, whereby group membership is not spatio-temporally stable. These dynamics have major implications at both population and individual levels, exerting an important influence[...]

Samantha C. Patrick, Auteur ; Stuart Bearhop, Auteur ; Thomas W. Bodey, Auteur ; W. James Grecian, Auteur ; Keith C. Hamer, Auteur ; Janette Lee, Auteur ; Stephen C. Votier, AuteurCurrent fishing extraction methods often generate huge quantities of dead or dying biomass that is returned to the sea in the form of discards. This practice produces a readily available clumped resource for many scavengers such as seabirds, but[...]

Votier, AuteurSeabirds are well monitored and protected at their breeding grounds but spend most of their life at sea, where they are less well monitored and afforded little protection. In an attempt to address this dichotomy, attention has been directed towa[...]

Stephen C. Votier, Auteur ; Stuart Bearhop, Auteur ; Jonathan E. Crane, Auteur ; Jose Manuel Arcos, Auteur ; Robert W. Furness, AuteurCompetition for food is widely cited as an important cost of coloniality among birds and much of the evidence in support of this hypothesis comes from studies of colonial piscivorous seabirds. However, for generalist seabirds able to switch betw[...]
Article
Paulo Catry, Auteur ; Stuart Bearhop, Auteur ; Miguel Lecoq, AuteurIn passerine birds, males are generally larger and dominant over females. In line with the dominance theory, in all known differential migrant passerines, females migrate further than males. However, there are alternative explanations to the dom[...]
