Broadly, I am interested in waterfowl ecology, conservation and management. I am particularly interested in Arctic-nesting waterfowl because of their remarkable migratory journey. Throughout the year, these birds must take risks to maximise breeding opportunities during the short Arctic summer. Study of population dynamics and individual decision-making allows us to better understand the implications of these risks.

Project Title: The demography of the Greenland White-fronted Goose
Funding Body: Wildfowl and Wetlands Trust and the University of Exeter, College of Life and Environmental Sciences
Project Description: The global Greenland white-fronted goose (Anser albifrons flavirostris) population has declined markedly since the late 1990s. Simple modelling shows consistently low reproductive success over the last decade, matched by relatively stable annual adult survival. Integrated population modelling techniques will be used to demonstrate the mechanistic cause of the decline. Metapopulation models will explore population dynamics between wintering flocks. Further, individual birds will be followed to examine how individual decisions made by white-fronts during each phase of the annual cycle (breeding in west Greenland, staging in Iceland and wintering in Britain/Ireland) affect migratory decisions, reproductive success and ultimately population size.
