I shall clearly have to pay more attention to them, and try to document them in some way, but the numbers of Hair-crested Drongoes going to roost in winter time near Hing Keng Shek, Sai Kung regularly exceed 67, exceeding 90 I think. That's during the period from 2004-5 to 2009-10, when I lived there.
When I watched regularly at Mount Austin from 1992-96, Hair-crested Drongoes were only ever seen on one weekend, but were seen nearly every year on that weekend ie the weekend falling between c 28/9 and 5/10.
A bit off topic on a thread that started off being about Black Drongoes I guess, so on that topic I remember Mai Po and environs used to be generally full of Black Drongoes towards the end of September. I believe the species breeds further north now, so maybe that's why peak passage events appear to be getting later and later.
I haven't seen one today!
