Howard,
I have seen young Sandwich Terns like the one you describe. The
bill of juveniles is typically smaller than the adults'. This is
mentioned in most texts. The color of the bill is a different matter.
Apparently some juveniles retain the yellowish-colored bill from the
downy stage which I can find described only in Bent. I remember
discussing this bill color with Claudia Wilds some years ago. She had
also seen such birds. May be we can find out the rest of the story when
the tern book comes out.
