Research
My research primarily concerns short-distance migration among birds. My PhD at the bird migration research group in Lund covered different aspects of partial migration (the occurrence of both migrant and resident birds in a population) in one of Scandinavia’s most common partial migrants, the blue tit Cyanistes caeruleus. There, I studied how individuals differed in physiological and behavioral traits such as hormone dynamics and avian personalities between migrants and residents, but also how partial migration differs from more regular migration.
By studying how the blue tit responds to weather and climate, I became interested in how climate change affects bird migration. Presently, I am doing my post-doc at the University of Oslo, supervised by Prof. Stenseth. This project aims to shed light on how bird populations respond to changes in local and global climatic factors, with respect to the evolution of timing of annual events. More specifically, I analyze long-term data on the Eurasian dipper Cinclus cinclus for studying population responses to climate change and phenology.
