Tracking Data 2011 and 2012

In 2011 and 2012 we fitted the offspring from the Dyfi nest with satellite tracking devices. Although we are no longer receiving data from any of the tracking devices you can still follow their migration routes and explore the areas they visited by following the instructions below.


It is now possible to follow the progress of the Dyfi Ospreys using Google Earth.

Google Earth is free to download and use. Please follow these step by step instructions to get up and running with Google Earth on your computer, and link to the Osprey migration satellite tracking data.


1. Click Here to download Google Earth to your computer.

2. Once it has finished downloading (less than a minute on a broadband internet connection) start the Google Earth application.

3. Close the Tip of the day box.

4. In the menu along the top, click the Add option, and then click Network Link as shown below:

7. Double click Dyfi Osprey Migration to see the full route in your Earth browser window: All three ospreys are shown on the left; Einion is Green, Dulas is Blue and Leri is Red. You can click each osprey to select or deselect that bird.

8. Double click in the Earth browser window, or use the controls on the right to pan, tilt and zoom the camera, and get a fantastic up-close look at exactly where the osprey has been on its long journey south:

9. Now that you have added the Dyfi Osprey Migration network link to your copy of Google Earth, it will still be there every time you open the application. The Osprey satellite data is updated every day but please be aware that Dulas and Einion send data back every two days, and Leri every three days. To make sure you are seeing the latest version, just right-click on Dyfi Osprey Migration in your places panel, and then select Refresh. The migration routes will then be updated to their latest versions.


10. Hover your mouse over a waypoint (one of the circles along the migration) and the time and date that the bird was at this point will show up in a little window. If you want to know more about the osprey at that point, click the waypoint and another pop-up window will appear with the osprey's latitude and longitude, his/her speed, altitude and heading. Enjoy!
