From Sun Moon Lake we drove to Augu Wetland, arriving just as the sun set. The next day we toured the wetland area -- there were lots of birds but the lighting that day was difficult....
Aogu wetland was formed on land recoved from the sea by the Taiwan Salt (Sugar?) Corporation and is currently the biggest wetland in Taiwan. The park, covering a total area of 1,465 hectares, encompasses lagoons, sandbars, marshes, mud flats, beefwood trees, mangrove swamps and windbreak forests, together with places where a mix of freshwater and seawater allows a great range of aquatic creatures to thrive. Large numbers of local and migratory birds can be seen. According to a survey conducted by the Council of Agriculture, Aogu is home to 221 bird species.
