Visitors are a rarity in many border regions, but it is these areas that provide a habitat for a wealth of wildlife. The same is true of Hong Kong. During spring and summer, Sha Tau Kok Hoi, in which the famous egretry in A Chau is situated, houses huge flocks of egrets and herons, an easily spotted species of waterfowl that perches on wetlands. They can be seen foraging for food by flying low to the ground from Fung Hang Family Walk, which is set by the sea. As soon as the trail enters the woodland, it reaches a viewing point on a knoll, overlooking the wetlands formed by the villages and fields in Kai Kuk Shue Ha, Fung Hang, and Nam Hang Mei. Thanks to the mountain ranges that separate this place from the hustle and bustle of the city, it has become an unspoilt paradise for animals and us.
