Habitat

110 acre reservoir surrounded by young cottonwoods and shortgrass prairie. used by both Cormorants and Am. White Pelicans.

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

The Sibley Guide to Birds after my observations.

Previous Experience

I have identified both Trumpeter and Tundra Swans in the past, but never in large numbers.
