觀察細節

Individual count using photos. Conservative and very careful about not double counting. Confident I can't see all of them that are hunkered down in the field. Huge flock of large white swans observed across three fields. Both trumpeters and tundras observed. Birds were not moving around. Only had one group of 5 trumpeters fly into the middle field and these individuals were subtracted from the count total just in case. Waited to submit list until I could look at photos on my computer to get a final count. Uploaded best example photos, but used 100+ photos to confirm number of individuals present. Multiple banded trumpeters observed. One for sure is 72P, the others I think are 14E and 70P. There were other banded birds, but was unable to get a view on the band numbers.
