    Details

    More distant photos of continuing HERG-type. P10 and P9 still growing so definitely a 2nd-cycle. Pale eye. The black bill at this age seems to suggest LBBG or something Asian but it looks like there may be some pale adult gray coming in on upperparts. Just a HERG with retarded bill color or HERG x LBBG? Or a Vega?

    With the medium gray now coming in experts like it for Vega. Peter Adriaens was the first to suggest Vega based on the J St. photos. Amar Ayyash also likes it based on the New Year's pelagic photos.
