Using optimality perspectives is now regarded as an essential way of analysing and understanding adaptations and behavioural strategies in bird migration. Optimization analyses in bird migration research have diversified greatly during the two r[...]

The island of Helgoland (or Heligoland; in the North Sea) was the very first place on Earth to be the focus of systematic studies on bird migration (since the mid-nineteenth century). The "Vogelwarte Helgoland" was founded in 1910, and since 190[...]

The evolutionary origin and the maintenance of extra-pair mating in birds has been a major field of study in the last decades, but no consensus has been reached on the adaptive significance of this behaviour for female birds. The genetic benefit[...]

Dispersal is an important process in ecology, but its measurement is difficult. In particular, natal dispersal-the net movement between site of birth and site of first reproduction-is important, since it determines population structure. Using si[...]

All organisms are adapted to their native environment, posing problems in terms of fitness costs for individuals that leave this environment. Other species constitute an important coevolving component of this native environment, with more than h[...]

Integrated population models (IPMs) represent the single, unified analysis of population count data and demographic data. This modelling framework is quite novel and can be implemented within the classical or the Bayesian mode of statistical inf[...]

The Aquatic Warbler Acrocephalus paludicola (AW) is the only globally threatened passerine species of continental Europe. The global population decreased by > 90% during the 20th century. AWs breed in Palaearctic fen mires and sedge meadows and [...]

Replacement clutches may increase the annual reproductive output of individuals and the population, but cause additional effort and may have fitness consequences. Whether longevity and lifetime reproductive success are affected by renesting is u[...]

Twice a year, songbirds breeding in the Western Palaearctic cross the largest desert of the world, the Sahara, to reach their African winter quarters. Recently, a radar study quantified this migration and demonstrated that almost all passerines [...]

Lindstrom (in Trends Ecol Evol 14:343-347, 1999) synthesized knowledge about "early development and fitness in birds and mammals", interesting tracks and challenges for future studies. Today, there is unambiguous evidence that Lindstrom's first [...]

For migrating land birds, the influence of extrinsic factors (e.g., weather and energetic condition) on stopover site selection relative to factors intrinsic to habitat (e.g., food) may be especially acute after crossing a large ecological barri[...]

Understanding the interactions of an organism and its environment is essential for us to integrate ultimate and proximate causation on a global scale. Organism-environment interaction includes all organisms including animals, plants, and non-euk[...]

The three main energy-demanding events in the yearly cycles of birds-breeding, moult and migration-tend to occur at different times of year from one another, with minimal overlap. The sequence in which these various events occur varies according[...]

GPS transmitters were used with the Argos satellite system to track two Light-bellied Brent Geese (Branta bernicla hrota) from Iceland to Arctic Canada, three Greenland White-fronted Geese (Anser albifrons flavirostris) from Scotland to west Gre[...]

One of the classic ecological questions is how predators affect population size. This is often assessed by measuring how many individuals are killed by a predator, yet such direct effects may only be a relatively minor part of population dynamic[...]

In this paper, I argue that to fully grasp the generation and maintenance of variation in the migratory phenotypes of (shore-)birds we need to expand our scientific search image and include developmental processes and non-genetic pathways of inh[...]

An ideal technology for non-invasive analysis of body composition should provide highly precise and accurate direct measurements of fat, lean mass and total water of non-anaesthetized subjects within minutes. We validate a quantitative magnetic [...]

Tree Swallows, Tachycineta bicolor, have been studied at nest box colonies at sites throughout North America. They can be easily aged, captured, repeatedly sampled, and their physiology and reproductive success measured across their lifetime. Th[...]

The use of measurements of naturally occurring stable isotopes of the light elements C, N, H, O, S in avian tissues and their associated foodwebs has grown tremendously during the last 30 years. Three primary applications of this approach have b[...]

Bird migration has evolved under the influence of annual and daily fluctuations in resource availability. Numerous passerine migrants migrate exclusively by night, maximizing the time available for foraging and feeding during the day. When held [...]

Although stopover habitats are used by many species as refuelling stations during migration and can be critical for survival and successful reproduction, they are rarely incorporated in year-round population models and conservation strategies. W[...]

Ecological barriers represent a challenging and potentially risky component of migratory flyways. Complex patterns involve large arrays of species and huge numbers of birds in crossing deserts, mountain chains and large stretches of sea. Despite[...]
