Western Water Rail in HK
Judging from photos on HKBWS forum, It seems to me that most of the recent Water Rail records in HK are Eastern Water Rail (Brown-cheeked Rail, Rallus indicus). May I ask how many Western Water Rail (Rallus aquaticus, presumably subspecies korejewi) are there in HK? Is there a good HK photo showing the undertail pattern? Thanks in advance.
