In most bird species, breeding individuals behave as central-place foragers during reproduction, commuting regularly between the breeding site and foraging areas to find food for both self-maintenance and offspring rearing. Such movements are constrained by the need to find enough resources around the breeding site in a short time and may be modulated by several factors, including resource availability, weather, and breeding p...

Biodiversity is decreasing at an alarming rate, and there is an urgent need to understand the demographic drivers behind population declines. Therefore, it is important to study the different stages of a species’ life cycle, including adult survival and productivity. It is still poorly understood whether adult survival or productivity has a stronger role in population change, and how the role of adult survival and productivity...

Synchronous fluctuations in species' abundance are influenced by synchrony in underlying rates of productivity and survival. However, it remains unclear how rate synchrony varies in space and time, contributes to abundance synchrony, and differs among species. Using long‐term annual count (number of adults captured), adult survival and productivity (number of juveniles captured per adult) data for breeding land‐birds at ringin...
