REPORT MARKED TUNDRA SWANS
November is migration time for Tundra Swans which pour forth from the north. All observers are asked to be vigilant for sightings of marked TUNDRA SWANS WITH BLUE NECK BANDS FROM ALASKA. An impressive effort has gone into marking 1873 individuals in the last three years. Your observations will be key to success of this effort!
TUNDRA SWANS WERE MARKED IN WESTERN AND NORTHERN ALASKA IN THE SUMMERS OF 2006-2010 WITH CODED NECK BANDS AS PART OF AN EFFORT TO LEARN MORE ABOUT THE TIMING OF MIGRATION AND MOVEMENTS OF SWANS RELATIVE TO BREEDING AREA.
NECK BANDS HAVE A FOUR-DIGIT CODE THAT BEGINS WITH A LETTER. CODES ARE READ FROM BOTTOM TO TOP. BANDS ARE BLUE WITH WHITE DIGITS, EXCEPT CODES T3##, WHICH ARE WHITE WITH BLACK DIGITS.

In 2008, 50 swans were implanted with satellite transmitters, many of which are still functioning. Birds with transmitters were not collared, but have a black antenna exiting near the base of the tail. The movements of these swans can be followed at our web site: http://alaska.usgs.gov/science/biology/avian_influenza/TUSW/index.html
