Деталі спостереження
The flock contained at least this many individuals, counted in the first of the three photos below. 218 birds can be seen there. Left out of this number are some of the birds that can be seen sitting on the rope in the pic. While the apparent size/tail-length difference is quite possibly an optical illusion, additional photos showed nothing but Boat-tails and we didn't note any other species in the flock in the field, there may have been some mixture in the flock. Prior to the point when the Boat-tails were moving along the edge of the marina for some reason, they'd been popping up only briefly in the marsh grass and had been very difficult to count.
