Data from: Male but not female zebra finches with high plasma corticosterone have lower survival

Blanca Jimeno, Michael Briga, Michaela Hau & Simon Verhulst
(1) The glucocorticoid axis is essential for coping with predictable and unpredictable environmental variation. Despite this vital function, attempts to link individual variation in the glucocorticoid axis to survival have yielded mixed results, which may be due to endocrine variation caused by uncontrolled variation in environment and life history traits such as reproductive effort. We therefore studied the link between the glucocorticoid axis and long-term survival using captive non-breeding zebra finches. (2) We quantified the...

Data from: Effects of experimental night lighting on the daily timing of winter foraging in common European songbirds

Arnaud Da Silva, David Diez-Méndez & Bart Kempenaers
The ecological effects of light pollution are becoming better understood, especially in birds. Recent studies have shown that several bird species can use street lighting to extend activity into the night during the breeding season. However, most of these studies are correlational and little is known about the effects of artificial night lighting on the timing of activities outside the breeding season. During winter, low temperatures and short days may limit foraging opportunities and can...

Data from: Vocal plasticity in mallards: multiple signal changes in noise and the evolution of the Lombard effect in birds

Adriana M. Dorado-Correa, Sue Anne Zollinger & Henrik Brumm
Signal plasticity is a building block of complex animal communication systems. A particular form of signal plasticity is the Lombard effect, in which a signaler increases its vocal amplitude in response to an increase in the background noise. The Lombard effect is a basic mechanism for communication in noise that is well-studied in human speech and which has also been reported in other mammals and several bird species. Sometimes, but not always, the Lombard effect...

Data from: Simulated moult reduces flight performance but overlap with breeding does not affect breeding success in a long-distance migrant

Barbara M. Tomotani, Florian T. Muijres, Julia Koelman, Stefania Casagrande & Marcel E. Visser
1. Long-distance migrants are time-constrained as they need to incorporate many annual cycle stages within a year. Migratory passerines moult in the short interval between breeding and migration. To widen this interval, moult may start while still breeding, but this results in flying with moulting wings when food provisioning. 2. We experimentally simulated wing gaps in breeding male pied flycatchers by plucking 2 primary feathers from both wings. We quantified the nest visitations of both...
