Viewing Conditions
Optics:
Kowa TSN 20 to 60 Variable
Distance:
probably about 750 feet
Light:
I was looking toward the sun; the sun was to my right as I looked at the birds. I was able yo get pretty good looks through my scope. Distance was more a factor than light.
Description of the Bird
6 white swans flew into the lake at considerable distance from me. I then looked at the birds through my spotting scope and observed yellow lores on at least two of the birds.
Behaviors: I saw the birds circle and drop into the lake; they then just floated along in a group.
Call: n/a
Plumage: adult and juvenile
Similar Species Discussion
I eliminated the Trumpeter Swan as I was able to see the yellow lores on several birds. Also I studied the border where the head met the bill and it appeared more rounded than pointed.
Resources Used
