Peregrine falcon banding | Linn Bergbrant Photojournalist

The peregrine falcon is the fastest bird in the world.

Johans Svennson climbs 40 meters down the steep to find the baby peregrine falcons.

Peter Lindberg is a scientist at University of Gothenburg and has put a lot of effort at saving and studying the peregrine falcons in Sweden.

The baby bird gets banded so the scientists know where it was found.

Blood exams are taken to find out about the toxic content, the sex of the bird and its relationship to other birds.

Peter Lindberg and Johan Svensson photograph the baby falcons before putting them back in their nest.

Only 15 days old. In two more weeks they will be able to use their wings.

When the peregrine falcon became a endangered species there were only about 10-15 couples in the whole country. Now there are about 175 couples.
