Thanks to modern light logger technique it’s now possible to track individual birds during their long migrations. Thus, questions like Where do they go? How fast do they fly? How do they find their way? are likely to soon be answered. For example, earlier this year it was discovered that the great snipe (Gallinago media) can fly to Africa non-stop at an average speed of 80km/h, (see blog entry from May) - a previously unknown strategy in bird migration!
However, despite the technical advances it is still hard work to get results. During 2011, journalist Joakim Lindhé and photographer Per Anders Rudelius followed some CAnMove researchers in their quest to find out more about the enigmas of bird migration.
