Non-breeding season habitat quality mediates the strength of density-dependence for a migratory bird
(The Royal Society, 2015-07-22)
Our understanding of when natural populations are regulated during their annual cycle is limited, particularly for migratory species. This information is needed for parametrizing models that can inform management and ...
Rainfall-induced changes in food availability modify the spring departure programme of a migratory bird
(The Royal Society, 2011-03-30)
Climatic warming has intensified selection for earlier reproduction in many organisms, but potential constraints imposed by climate change outside the breeding period have received little attention. Migratory birds provide ...
Linking fluctuations in rainfall to nonbreeding season performance in a long-distance migratory bird, Setophaga ruticilla
Research on long-distance migratory birds has yielded some of the strongest evidence that shifts in climate are changing ecosystem processes. Much of this work has focused on understanding whether rising temperatures on ...
Plumage brightness predicts non‐breeding season territory quality in a long‐distance migratory songbird, the American redstart Setophaga ruticilla
(John Wiley & Sons, Inc, 2009-01-13)
Many species of birds exhibit brilliant ornamental plumage, yet most research on the function and evolution of plumage has been confined to the breeding season. In the American redstart Setophaga ruticilla, a long‐distance ...
Nonbreeding Habitat Occupancy And Population Processes: An Upgrade Experiment With A Migratory Bird
(Ecological Society of America, 2005-09-01)
Evidence is accumulating that winter habitats occupied by migratory birds produce differences in individual condition that can carry over into subsequent stages of the annual cycle. Despite strong observational evidence, ...
Winter rainfall predicts phenology in widely separated populations of a migrant songbird
Climate change is affecting behaviour and phenology in many animals. In migratory birds, weather patterns both at breeding and at non-breeding sites can influence the timing of spring migration and breeding. However, ...
