I had a quick stroll up the hill to the first set of falls.
My first views of Mountain Tailorbird in HK (as per Mikes earlier post) didn't even require bins, with two birds most accommodating.
Others included:
Japanese Sparrowhawk (M)
Crested Serpent Eagle
Striated Heron (Juv)
Dusky Warbler
Arctic Warbler (3)
Japanese Flycatcher (with RC Babblers and BW Minla)
Verditer Flycatcher
Pygmy Wren Babbler calling too. Dont know the calls for Lesser Shortwing though.
