Article
Farzaneh Etezadifar, Auteur ; Richard Major, Auteur ; Paul G. McDonald, AuteurIn birds, several physiological characters have been proposed and tested as possible criteria of age. Among them, skull development is likely to provide a valuable reflection of other physiological developments, however the relationship between [...]
Article
Juliana Holt, Auteur ; Ahmad Barati, Auteur ; Paul G. McDonald, AuteurCommunication is an essential component of social interactions between individuals, particularly in larger group sizes. To gain further insight into the factors that underpin cooperative behaviour, herein we examine the acoustic repertoire of th[...]
Article
Christa Beckmann, Auteur ; Paul G. McDonald, AuteurNest predation is the most important source of reproductive failure for many bird species, thus placing nests in ‘safe’ locations that minimise predation risk is paramount to maximising fitness. After a nest predation event, some species have be[...]
Article
Amanda J. Dare, Auteur ; Paul G. McDonald, Auteur ; Michael F. Clarke, AuteurBell miner (Manorina melanophrys) colonies are closely associated with decreased avian abundance and diversity and an apparently associated increase in psyllid abundance. However, a causative link between the presence of bell miners and increase[...]

Article
Robert A. W. Kennedy, Auteur ; Christopher S. Evans, Auteur ; Paul G. McDonald, AuteurIndividual differentiation is usually advantageous in maximising the fitness benefits of interactions with conspecifics. In social species, where intraspecific interactions are frequent, this is likely to be particularly important. Indeed, some [...]
Article
Sara M. Kross, Auteur ; Paul G. McDonald, Auteur ; Ximena J. Nelson, AuteurIntroduced mammalian predators have been implicated in the majority of avian extinctions on oceanic islands around the globe. Nowhere is this more apparent than in the decimated New Zealand avifauna, where introduced predators remain the primary[...]

Griffith, AuteurThis article responds to the recent prominence of ornithological literature advocating the plucking or clipping of feathers to obtain DNA in avian studies. We argue that the practise of feather plucking or clipping should be strongly discouraged[...]

Paul G. McDonald, Auteur ; Catherine F. Heathcote, Auteur ; Michael F. Clarke, Auteur ; Jonathan Wright, Auteur ; Anahita J. N. Kazem, AuteurAcoustically-mediated individual discrimination has been the focus of much investigation in ornithology. For cooperatively breeding species, strong selection pressure favouring individual recognition during acts of altruism is predicted under ma[...]
