Red-throated Loon	Saylorville Dam	Saylorville Reservoir, off of west end of dam	freshwater lake	The documentation form by Jim Dinsmore is the only one submitted and forms the basis of this record. Other observers include Bery Engebretsen and Dennis Thompson. \| Elimination of similar species: I spent a long time puzzling over these birds, both in the field and later when I had several references to consult. None of the guides I looked at showed a bird that looked like these. Common (a small one): removed on the basis of size (birds too small for Common Loon), the thinner and bicolored bill, and the color pattern on the neck. At this time of year, all of the Common Loons I have seen (and saw on Saylorville that day) were distinctly white on the front of the neck with some partial bands of brown extending back in to the white. Pacific Loon: Eliminated on behavior (head posture), lack of a distinct dark/white line along the side of the neck, lack of chin straps across neck, and presence of brown on front of neck. Also the gray/brown contrast between neck and back would point away from Pacific but not eliminate it. Red-throated Loon: This is what I first thought the birds were but as I viewed them, I convinced myself several times that they were Pacific Loons. However, the combination of characters listed above seem to eliminate the other two possible species and also are positive characters for the Red-throated Loon. One character that puzzled me was the size of the bill. At least some of the guides (Advanced Birding esp) show the Red-throated Loon as having a tiny bill, much smaller than on this bird but those illustrations do not match those in other guides which emphasize more the shape of the bill than the size. \| The original documentation form event lasted from 07:45:00/08:45:00.
