Observer’s Previous Acquaintance With This or Similar Species

Commons loons are seen and heard in this area year round, but usually spring through autumn. However, they can be seen in the winter with what I describe as wearing their winter plumage, but what Cornell Lab of Ornithology describes as non-breeding/juvenile. I have also observed Common Loons on Attean Lake in Jackman, Maine so do have previous knowledge of the physical shape of a loon as well as its vocalizations.

I certify that any attachments included with this report were captured during this observation event​​.
Description of Habitat

Water surface of Lake Champlain. The lake did not ice over during Winter 2024.

Behaviors Observed

Paddling/swimming on and diving beneath the water surface.

Description of Vocalizations

Eerie tremolo calls.

Verbal Narrative & Description of Observation

I did not make any notes for this particular observation, but I suspect that I saw a waterbird on Lake Champlain as I was walking indoors past my glass French doors and grabbed my binoculars to view it before I entered it into my eBird account as an incidental. Note: I have seen single Common Loons during past winters.

Smaller than a goose and larger than a crow.

Head

Gray-colored head and white throat.

Breast was white. Did not see belly, flanks, or under tail coverts.

Tail

Did not see tail.

IMPORTANT: What similar species were eliminated when making the identification and how was this bird different?

Double-crested Cormorant. Profile can be deceiving if it is in the middle of Lake Champlain, but can be positively identified by using binoculars.

Other Notes & Comments
