I should have added that it could also be a "Nelson's Gull" (Herring x 
Glaucous) if the mantle is not as dark as it appeared in the first photo by 
Jim, but if it IS darker above than the adult Herrings then Great 
Black-backed might be a more likely parent.  It is always tricky to try to 
judge mantle shades from photos...

Does this gull have white (or mostly white) primaries?  The wingtips were
hidden in Jim's photo, but in Jym's photos they appear to be whitish.  Yes,
this would make a difference, and suggest that perhaps this bird may be a
Great Black-backed x Glaucous Gull.

(Sorry, don't know why my first message looks so messed up.  Here's a
cleaner version.)

Jim's photo came across fairly dark.  My photos (such as they are) show the
mantle to be not as dark as in Jim's.  The key point, however, which does
not show in Jim's photo, is that the wingtips were white, not dark.  John
Dixon was also concerned about the mantle being darker by a shade or two
than the HERGs in the vicinity.  Checking Dunn and Howell's Gulls of the
Americas when I got home, I'm wondering if this bird is a GBBG X GLGU.

The best photos I was able to get are here:  http://flic.kr/s/aHsjDWcQoo

Analysis and feedback are welcome!

Jim, your hybrid gull looks more like a Herring x Great Black-backed, if I
am looking at the correct bird.  The mantle color appears to be a dark gray
(darker than the nearby Herrings), which would be more expected from a bird
with Great Black-backed genes.  A "Nelson's Gull" should as light or lighter

in mantle color than a Herring.

Hi all,


There were a variety of Gulls present this morning at the mouth of the
Milwaukee River on the lakefront, under the Hoan Bridge. One of highlights
was a gull thought to be by Jym and John D a Nelson's - a hybrid Glaucous x
Herring Gull. Also present were 5 Glaucous Gulls, 1 Great Black-backed Gull
and a Lesser Black-backed Gull. Other species present in the area, an
American Kestrel and Horned Grebe. If I have something mislabeled, please
let me know, thank you! It was a nice morning to be out among many other
birders.



A link to a few of today's images if you care to view them:
