Field Marks and Identifying Characteristics: |
This, I believe is the same gull I reported on 1/8/11. Today's gull was 5.3
miles down the road from where I observed the gull on 1/8. Both gulls looked the
same. I now have pictures & thought I should write up a new report with the
pictures. However, my descriptions are the same. This was a small, very pale gull with brown mottling on the wings, scaps and somewhat on the chest. If you looked at it with the naked eye, you'd almost think this was a completely white bird. The primaries of the bird were almost purely white. The bird had a completely dark and smaller bill. The size of the bird was that of a California Gull & I compared its size with nearby California Gulls, Herring Gulls, and Ring-Billed Gulls. The structure of the bird reminded me more of a Ring-Billed gull than anything else; it was a smaller, weaker looking gull. This bird immediately struck me as something that I had never seen before.

Similar
species and
how were they eliminated: |
1st Cycle Glacous Gull- Smaller sized that Glacous. We had a Glacous fly in
about an hour later & noted the size difference. The Glacous dwarfed the
California Gulls when we saw it, and the Iceland was about the same size. Also,
the bill was smaller than that of a Glacous & was purely black. 1st Cycle Kumlien's Gull- Lighter upperparts that Kumlien's, and the wingtips had no brown or coloration compared to Kumlien's. Also, the bill was completely dark compared to bicoloration of a 1st cycle Kumlien's. 1st Cycle Glacous-Winged Gull- This bird didn't have the grayish overall that a 1st cycle Glacous-Winged Gull has. Bill was smaller and less stout. Bird was smaller than Glacous Winged Gull. |
