Making a journey to Co Island, excursionists will be amazed to witness nests of storks hung on branches and baby storks learning to fly on bamboo tops.

Their twitters in harmony with the murmur of leaves and whisper of winds together with the buzz of other insects make a symphony for tourists to relax and leave daily stresses behind.

Moreover, the peaceful and splendid surroundings is another reward for tourists. An Duong Lake in the island is also home to many fish and many aquatic species, many of which are listed in the Red Book of Viet Nam. Locals say that September is the time that thousands of storks and birds come to the island and stay until April of the following year.

Since 1994, local authorities have preserved and developed tourism for the island, attracting about 40,000 tourists every year. They grow more plants and trees to offer more space for birds.

Authorities have also approved a project on developing and preserving the ecological system in Co Island. The project costs VND100 billion and includes three phases which will be completed by 2015, according to Vietnamplus.

If tourists have a chance to visit Hai Duong Province, Co Island is a must-see place that should not be missed.
