To follow migration journeys on your computer you can use Google Earth - a free piece of software that simulates our planet with satellite photography.
Step by step
Downloading Google Earth for free

Adding the data to your Google Earth software
It's easy to add the satellite data to your copy of Google Earth - just follow the steps below:
- Launch the Google Earth software
- Go to the Add menu and click Network Link...
- Enter bird name into the Name field (Loch Garten Ospreys / Tollie Red Kites / Mull white-tailed eagles / Turtle doves).
- Paste the appropriate address below into the Link field
- Click OK to add the data to the Places list on the left hand side of the screen.
Using Google Earth to keep an eye on the birds
Once the birds are in your list of Places you can double click them to zoom straight to their location. You can also use the standard Google Earth controls to zoom and pan around the globe.
Choosing how often to update Google Earth
The satellite data will be updated approximately once per day. To make sure you have the latest updates, you can tell Google Earth how often to refresh its data. To do this, right click on the bird item (for example Mull white-tailed eagles) in your Places list and choose Properties. Go to the Refresh tab and change the options so that it updates periodically every 12 hours.
