Field Marks and Identifying Characteristics: |
Eli and I were scoping the lake for loons when I scoped onto a loon that
quickly dove. In my quick glance, it seemed as if it had a bill that was
upturned, so I was thinking it was possible that we had found a
Red-throated Loon on Utah Lake. It came back up onto water and I was
able to get Eli on the bird. We then spent the next fifteen minutes
watching the bird and discussing the different things we were able to
identify that made it a Red-throated loon. The main thing was the
shorter, sharply pointed bill, that remained point at an angle upward
the entire time we watched it, except when it consumed a fish, and we
weren't able to tell bill angle at that point. We also could catch
glimpses of white on the flanks as it would move on the water. It had
what appeared from our distance to have a dark and a gray neck and top
of the head. The under chin area was white, then went to a grayish or
dark coloring on the throat, due to light conditions we couldn't be
certain if it was leftover red from breeding, or more in line with a
juvenile bird, but leaned towards a juvenile bird. uWe also noted a
white chest, and cheek of the bird with they eye placement right around
where the white met the gray. As for the head shape, the head appeared
flatter on top vs a more round profile of a Pacific Loon. Unfortunately
it wasn't close enough to tell the patterning on the back.

| Song or call & method of delivery: | none |
| Behavior: | bird was actively swimming about 100 yards off shore and also actively diving. We also were able to see it catch a fish and eat it. |
| Habitat: | shallow freshwater lake |
| Similar
species and
how were they eliminated: |
Pacific Loon, the continued upturned or angled bill of this loon, would
eliminate a Pacific Loon, as would the whtie flank we could see. Also a Pacific Loon has a more clean white
throat with a necklace, that this bird did not have Common Loon- The lack of a large straight bill, and overall size eliminated a Common Loon. Yellow-billed Loon- The smaller size, and smaller bill that wasn't huge and yellow, eliminated this species Common Merganser and RB Merganser- Many Common Mergansers were in the area, the females of both birds would have a more shaggy crest, which this didn't have, and a male would have a greenish head from either speices Western/Clark's Grebe. These would be too small for the bird we watched, and the bill color of yellow or olive yellow would not be conducive with the bird we saw. |
| Previous
experience with this & similar species: |
I've seen multiple Red-throated Loon in non breeding plumage, and juveniles. |

| Additional comments: | A few days prior Bryant Olsen had located a Red-throated Loon on north shore, and I am not completely certain if they are different, birds or the same bird, so I am submitting a record. I also emailed photos. |
