Hi Mr Tai
Wong Lung Hang which is behind Tung Chung on the north face of Sunset Peak is a good wooded area. Its about 15 minutes walk from the MTR station or catch any of the buses going to the south side of Lantau and ask the driver where to get off.
I would also suggest the coastal trail from Tung Chung to Tai O, checking out the side trails at San Tau. Shao Lo Wan and Sham Wat on the way. As you approach Tai O you may also see Chinese White Dolphin.Not sure which of the local buses brings you closes to the start - presumably the one to the Yat Tung Estate.
The woods around the back of Mui Wo can also hold migrants in autumn.
If you fancy a bog walk you can either walk from Tai O to Shek Pik or the reverse. Buses to Tai O, or Ngong Ping will drop you at Shek Pik if you want to start there.
I look forward to hearing what you find
Cheers
Mike
