a few more records
I have come across a few flocks in Tai Po Kau recently: two flocks, 5 birds and c.10 birds, 9-Feb-2013; one pair 15-Feb-2013.
However, I also have other winter records for TPK: c.5 in a birdwave 2-Feb-12; and a flock of c.12 on 16 Dec 2011.
(Any other records I have are from Upper Shing Mun (winter) and Tai Mo Shan (June) - but I rarely visit these areas)
