One of the main reasons I wanted to count waterbirds at Whitefish Point was the large numbers of Long-tailed Ducks that migrate through the area. This fall did not disappoint; a total of over 27,000 migrated by the point, most of which were recorded in October. More than 8,300 flew by on a single day in October. This flight consisted of a handful of flocks numbering between 400-500 birds; seeing flocks of this size is extremely impressive.
Take a look at the photo below. How many Long-tailed Ducks, without individually counting, do you think are in this flock alone? (all birds in the photo are LTDUs)
