Whether your interest in Tundra Swans, Cygnus columbianus, is focused on their patterns of migration, their susceptibility to avian influenza, or is simply based on their majestic beauty and the pleasure to be derived from watching them, then the Swan Surveillance and Research page of the USGS’s Alaska Science Center website is something about which you should know. In addition to providing a host of interesting and useful information about Tundra Swans, including a great map of their migration flight paths, it includes one of the, for lack of a better word, coolest uses of Google Earth that I have thus far discovered – a link to a file which allows anyone interested to view the daily movements of fifty Tundra Swans implanted with satellite transmitters through the Google Earth application.
Peace and good bird watching.
