Thanks, Brendan & the overssas expert.
I was asking questions about the Po Toi bird rather than pushing ID as Wandering. Though the nasal groove still seems to me to exceed 50% of bill length, the lack of grey on the flanks and the fairly obvious edge-spotting do stand out. No problem as far as I'm concerned in ID-ing as Grey-tailed.
As far as I know, the only record within Chinese waters (taking a conservative view of Chinese maritime territory here!) is one in Taiwan on an unknown date in autumn 2088. Can anyone provide more details of this? And does anyone know of any other credible records?
