A female falcon was equipped with a satellite tracking system in South Africa before migrating to Finland In just 42 days. Image shows tracker data where she flew over 10.000 km across 19 countries at an incredible average speed of 230 km per day and nearly in a straight line.
One would wonder how can a bird achieve such majestic feet. Earth's magnetic field plays a vital role in everything from animal migration to protecting the Earth from the Sun's harsh solar wind. Birds have cryptochrome, a protein that is responsible for visually detecting the earth's magnetic field a phenomenon called magnetoreception.
While the exact way that birds visualize their path to be able to traverse 10 000 km is still under study it is widely believed that they depend on magnetoreception rather than strong memory. The longest distance to be traveled by a bird is around 25 000 km which was recorded in 2014 when a Finnish honey buzzard went on a round trip from Finland to South Africa via the Black Sea
