Causes and consequences of mate switching


The majority of bird species are socially monogamous (~90%). Partners can stay together for lifetimes, but may also decide to 'divorce'. The rates of divorce vary drastically across species, populations, and individuals.

Why do some partners stay together, whereas others divorce? What are the consequences of losing versus keeping a partner?

During my PhD, I studied this question using a long-term dataset on Seychelles warblers (Acrocephalus sechellensis). You can find my thesis here.
The Seychelles warbler project is a collaboration between The University of Groningen, The University of East Anglia, and The University of Sheffield. Read more on the project here
