After banding 20 Western sandpipers and fitting radio transmitters last Monday and Tuesday, Lousie Vincencio form Fish & Wildlife and myself took to the skies to survey the numbers of shorebirds around Grays Harbor. We were also looking to locate the birds we marked and hopefully find some which had been fitted with radios either down on the Great Basin or San Francisco.
Found a rough total of 75,000 birds in the entire estuary - not spectacular but neat to see all the same.
18 of the 19 birds fitted with transmitters at Bowerman Basin were located. The 19th has been located on the Fraser River. We also managed to locate 3 birds from San Francisco.
Apart from trying to find out how rapidly Western Sandpipers move from California and Washington up to the Copper River delta, in Alaska, the importance of each staging site and the areas they use at each site is slowly being uncovered.
