Otherwise, the slender, upturned bill, the head posture, the contrast between the back and the neck, and the gray neck and white throat eliminated Pacific and Common Loons. | The original documentation form event lasted from 13:46:00/15:43:00.

Red-throated Loon

Pleasant Creek State Park

Pleasant Creek L.

artificial, deep-water lake
|
The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. | Elimination of similar species: The size of the bird, shape of the bill, and contrast between light and dark argued against Common Loon. Pacific Loon would have a straight bill and darker top of head and back of neck. I did not see any chin strap, but this would have been difficult to see. The fact that I saw the eye in the white area appears to exclude Pacific Loon. The upper parts were lighter than in the two Pacific Loons that I saw this fall. The relatively white fore-neck and face suggests an adult. | The original documentation form event lasted from 10:05:00/10:30:00.

The documentation form by Mark Proescholdt is the earliest and the one that forms the basis of this record. Other documentation forms by Beth Proescholdt, John Paulin, and Thomas Kent were submitted later. Other observers include Russ Widner, Caryn Hurd, Chris Paulin, Andy Hurd, Stacy Smithson, and Dawn Schwebach. | Elimination of similar species: A Basic-Plumaged Pacific Loon has no white or pale area above or in front of the eye. It also has a sharp vertical division between dark and light on its neck. A Common Loon is bulkier and bigger and has a large thick bill whose mandibles are straight. | The original documentation form event lasted from 14:00:00/16:00:00.

The documentation form by Ann Johnson is the earliest and the one that forms the basis of this record. Another documentation form by Tanya E. Bray was submitted later. Other observers include Babs Padelford, BJ Rose, Ross Silcock, and Tim Schantz. | Elimination of similar species: Cormorants could be eliminated by bill shape, among other characteristics. The bird had some similarities to a Western Grebe, but the grebe would hold its head parallel to the water, has a longer neck, and does not show the contrast between head/nape and back. Common Loon was eliminated by posture, size and shape of bill, contrast of lighter head and darker back, and more diffuse separation of upper and underparts. Pacific Loon was eliminated by the grayer underparts, diffuse separation of upper and underparts, posture, and sharp upward angle on lower mandible. | The original documentation form event lasted from 11:50:00/12:15:00.
