From thermal to flyway: how innate and external factors shape migration patterns of long-lived raptors?? Bird migrations have stumped humankind for millennia and inspired some particularly crazy theories among the naturalists of yore. Even now we realise that swallows don't hibernate on the bottom of lakes we still know very little about the lives of migrant birds outside the western world, and how they find their way across the globe. Thankfully, however, the advent of advanced biologging tools and remote sensing technology increasingly enables us to escape our ground-based human perception of the world, and to try and look at the world from a migrant bird's perspective. Large and long-lived raptors are especially useful study species in this regard because they can carry tracking devices capable of measuring behaviour with high resolution and precision at a global scale and for long periods of time. In this talk, I will summarise how I have combined movement data and atmospheric models to understand how weather shapes the flexible migration strategies of European Honey Buzzards (Pernis apivorus) from local to flyway scales. Using longitudinal tracking data I will further show how population-specific flyways of this species emerge from a largely stochastic individual learning process, even though soaring raptors are usually thought to learn traditional flyways through cultural inheritance. My talk will end with a brief outline of the research I am conducting into the migration strategies of Eleonora's Falcons (Falco eleonorae) for my JdlC postdoc at EBD.
