Article
R. Lockwood, Auteur ; J. P. Swaddle, Auteur ; J. M. V. Rayner, AuteurIn this paper we review the existing methods of quantifying avian wingtip shape, and compare their efficiency at detecting morphological adaptations to migration. We use multivariate methods to derive two novel measures of avian wingtip shape, p[...]

J. P. Swaddle, Auteur ; E. V. Williams, Auteur ; J. M. V. Rayner, AuteurWe investigated the effects of the plumage changes associated with moult on the anti-predator take-off performance of European Starlings Sturnus vulgaris. By altering the plumage to simulate moult, we have isolated the biomechanical consequences[...]
Article
J. P. Swaddle, Auteur ; R. Lockwood, AuteurAvoiding predation is an important factor in avian life-history strategies and there are many examples of adaptations that appear to decrease predation risk. However, we are not aware of any studies of structural morphological adaptations to red[...]
Article
E. V. Williams, Auteur ; J. P. Swaddle, AuteurThe effects of natural moult on avian flight performance have received relatively little attention, yet moult is an important part of the annual cycle. Quantification of flight costs will help to explain the diversity of moult patterns observed [...]
