Incredible. A female falcon was equipped with a satellite tracking system in South Africa before migrating to Finland. Image shows tracker data. In just 42 days she flew over 10.000km at an incredible average of 230 km per day and almost in a straight line.

The "falcon" on the map seems to be Honey Buzzard Päivi, who has made 6 round-trips between Finland & South Africa: https://satelliitti.laji.fi/?lang=en&id=JX.697

It's interesting because it looks like she flies a very different route from north to south than south to north. I wonder if this is to take advantage of wind patterns or different feeding at different times of year.

@mikkohei13 @VATVSLPR yes could well be that, also I imagine the weather conditions would be different on her outward and inward journeys.

There might also be some differences because of breeding. European honey buzzards breed in Europe, which means she's probably escorting young on her journey south. If she's still escorting them on the trip back north, they're a lot older and more mature. That might factor into choice of migratory route, too.
