Using technology to follow the movements of birds, animals and fish is an interesting application of technology. It is fascinating to me to see the places other species will travel. Recently, someone from Russia who calls himself “Valery35” at the Google Earth Community, has published tracks of birds in Russia 
Once you download the GE file above, you will need to open the “Birds” folder in your Temporary Places and turn on the tracks for the different birds. I found it particularly fascinating to watch the Stellar Sea Eagle as he migrated south along the east coast of Russia, stopping for a while at presumably the best hunting grounds along the way. Some of the birds have a photograph and the datasources are documented in a placemark description. Good work Valery35! Cpacibo!
