Abstract

Some birds breed at the same location every year, some birds change sites a lot. Movement between the first breeding site or group and other groups or sites is called breeding dispersal. This breeding dispersal is dependent on the nest site fidelity. In this thesis I try to answer the following questions: In what way do environmental factors influence the nest site fidelity of birds? Is there a difference in these influences between migratory birds and resident (non-migratory) birds? I try to to distinguish which factors are for birds the most important factors in breeding dispersal, while looking at food, interspecific competition, intraspecific competition and mate fidelity. In the end I have to conclude that dispersal depends on a combination of environmental en non-environmental factors and it depends on the species and the circumstances which factors are more important. I suggest reasons why I cannot draw any specific conclusions and I suggest that to get more detail on these processes research should be broader. Not look at one factor but examine more factors influencing one species, one population. If the same type of research is done on several species, one could draw better conclusions on general patterns, like comparing migratory and residential species.
