This year I supervised a master thesis about bird migration. I learned that birds can migrate over very long distances and I tried to find a dataset that would show that. Behold… the almighty Swainson’s Hawk, a bird that migrates from Canada all the way to the Pampas of Argentina. What I found fascinating is the migration path is very similar on the way south and back north. From my student/colleague I found out that it isn’t very well known how birds orient themselves, whether they use the magnetic field, the geographical features of the landscape or something else. The data is downloaded from the Movebank platform, a free online database of animal tracking data. You can check out the interactive version on labs.esri.com/bird-migration and the code on GitHub.
