I have recorded Brownish-flanked Bush Warbler Cettia fortipes at Lung Fu Shan in the past, or at least on the road up to the Peak, near the old battery as I recall. They seem to prefer shrubby hillside, or thinner woodland type habitats and while they are not common in Lam Tsuen Valley itself have been fairly regularly recorded in the lower parts of the Ng Tung Chai trail. They are quite widespread in Sai Kung too, eg at Ho Chung (upper valley bottom, lower area of woods, and I heard one today on shrubland above my home in Wong Chuk Shan San Tsuen above Sai Kung Town.
They quite like bamboo too - I once saw one in Tai Po Kau at the bamboo clump on the Red Walk, but are otherwise unknown there I believe.
