I am posting this as a recipient of the forward from Les Willis; I am not
sure that Phil Davis is around right now.  

Best,

>In regards to the Ivory Gull report from CBBT on Sat. 9/12/98, I am not
>sure how it came to be an Ivory Gull report.  I spoke with both observers
>the morning of 9/12 and they did not mention anything of the kind but did
>highlight an unidentified gull on isl. 4.  This is the only report of note
>they mentioned in an otherwise very slow morning.  As usual, I had
>questions about the unidentified gull (which they clearly favored leaving
>it as) and the description would seem to rule out Ivory.  It was on the
>rocks of isl. 4 with terns.  It was judged to be small, "about Bonaparte's
>size", with a "gray head", "white mantle and white tail with black spots on
>the middle tips. The tail was square."
>Further, the mantle was described as being white, including the inner
>wings, with a black wedge along the outer hand forming a slim triangle, the
>broad part being the tips of the outermost p's. Intreguing yes, Ivory Gull
>no (unless unequivocal photos prove otherwise).  It would seem ludicrous to
>claim an Ivory on this lattitude in Sept.  The observers at the time made
>no claim.

>While on the CBBT later that day, four of us studied an odd tern that
>matched this description (although we didn't see it as well).  The bird was
>only seen perched and indeed was white on the mantle with a gray head.  Its
>breast was facing us and it did alot of preening.  The pecular aspect was
>that the bird had some sort of dye or oil or something spotting its face,
>neck and upper breast.  Where it was densest, the shade was dark (head),
>but on the breast it was more spotted and clearly had a emerald-green
>sheen!  Often looking dark gray, the green was obvious to all when the sun
>hit it full.
>Its bill was fairly long and stout with a blunt tip.  It was reddish orange
>distally and black from about mid way to tip.  I suspect that this bird was
>a juv. Common tern but again I didn't stay with it long enough (time was
>short as we were a team on the Kiptopeake Challenge).

>Any further thoughts are welcome.
>I'd like to hear if there were any additional sightings!
