On New Years Day 2016 a bird appeared in Duluth. This time we were there at daybreak on day 3 of its visit yesterday. The bird made us make all of about 90 seconds before it appeared in the predawn overcast.
It's hard to explain how intensely white the bird was with pics taken before the sun is up or through the clouds. Just about all gulls are white below, but this bird was noticeably whiter than the surrounding Herrings. The white upperparts obviously contributed as well. Aside from the throat on a White-throated Mountain-gem I can't think when I've seen a brighter white.
The bird swirled and circled about in front of us along the pier where yesterday some people had left some salmon for it.
The bird was bigger than I expected though is obviously considerably smaller than a Herring.
