Very early record! I have no Avifauna of Hong Kong in hand and so cannot check it. Would it be the earliest record for this species? Author: wgeoff Time: 29/09/2013 17:51
Earliest autumn for Black-tailed Gull is 30 August 1987, also at MPNR.
We will shortly be publishing a new HK Data List with data as at end 2012.
