Scientists fitted a European honey buzzard with a GPS tracker. The bird flew for 42 days, covering more than 10,000 km from South Africa to Finland and helping researchers uncover the secrets of one of nature's greatest migrations

A European honey buzzard fitted with a GPS tracker flew over 10,000 km from South Africa to Finland in 42 days.

The tracker provided near real-time data on altitude, flight speed, stopover locations, and travel patterns.

The research was led by Dr. Patrik Byholm as part of Project Honey Buzzard.

The journey crossed deserts, mountain ranges, and multiple countries to reach breeding habitat in Finland.

The data revealed how the bird timed flights and selected energy-efficient routes based on weather and landscapes.
