I saw the Walla Walla Lesser Black-backed Gull on Sunday morning. Much of
the time it was in the fog, but when the fog cleared we had good scope looks
for about 20 minutes. Then the bird flew and I had a good view of its
departure.

I did not see anything about this bird that would suggest it to be a 3rd
year gull. Only the dark spot on the bill even hinted at its being anything
other than an adult. I think that a 4th year individual is a reasonable
conclusion, but certainly not a 3rd year.

>Hi Tweets,

the

but
>I am thinking that it is a 4th winter bird with only the bill having a
slight

tail,

>But take a look at the 3rd winter Lesser Black-backed Gull on Joe Morlan's

the

>I have had experience observing all ages of LBGU's at close range at Cape

of

Lesser

>I have looked in the book Grant's Gulls, 2nd Edition, page 104 ,and it
states

>I'd like to hear what anyone else thinks about this, since I have yet to
read
