During my PhD I worked with the flight behaviour of nocturnally migrating passerines. I used tracking radars to make exact observations of their flight behaviour. I investigated flight speed differences between spring and autumn migration and how the pattern of nocturnal migration during the night is affected by midnight sun conditions in the Arctic. I also investigated how the coastlines effected the flight direction of migrants. At our main study site Falsterbo, in south Sweden, I had the opportunity to combine my radar data with data from a radio telemetry system on the peninsula and the longstanding ringing regime in the area. We used this to investigate flight directions during different flight stages and to study reverse migration. I have also worked with comparative studies of insects and birds, where we could show that nocturnally migrating moths and passerines archive similar ground speeds and flight directions by using contrasting responses to winds. My supervisor was Professor Thomas Alerstam.
Currently I am a post doc at the Swiss Ornithological Institute in Sempach, studying large scale bird migration patterns by use of weather radar data.
