Habitats vary in terms of food and predation risk between each other and over time. The aim of this study was to describe the daily cycle of habitat selection and movements of Taiga Bean Geese Anser fabalis fabalis during spring and early summer. For that I used data from 11 Taiga Bean Geese marked with GPS-transmitters in Vilhelmina county, Sweden. I coded every position to a habitat and calculated length of movements between the positions. In most cases the geese spent the night at wetlands and agricultural fields, probably feeding, and the day close to lakes and streams, probably resting. The geese moved between those habitats in the morning and in the evening. These movements between habitats are more likely due to change in predation pressure than resource depletion of the first habitat.
