Occurrence Remarks |
The documentation letter by Ken Lowder is the only one submitted and forms the basis of this record. Other observers include John Daniel. | Elimination of similar species: It acted differently from the Common Loons. When it dove, it "reared back" its head, as though it were "winding up" for the dive. The Common Loons did not do this. In the Walsh article, this behavior is discussed. On page 26 of his article, Walsh states that "both Pacific and Artic Loons have similar diving motions." I do not believe our bird was a Pacific Loon. I base this judgement on overall body size, bill size, and the distribution of white coloration in the head/neck, waterline, and flank areas. Our bird was essentially similar size-wise to the accompanying Common Loons. The bill was also similar to Common Loon. It was not upturned and this as I would have expected with Red-throated Loon. |

Event Remarks |
The day was warm and sunny. We were right on the dam at a range to the bird of about 50-60 yards in the mid-afternoon, so the sun was at our back allowing for very good observation. We both had spotting scopes. I use a Kowa TSN-4 and John has a Swift Spacemaster. |
