Coringa wildlife sanctuary , the second largest stretch of Mangroves forests with 260 Bird species is located in East Godavari, 18 kms from Kakinada on Kakinada to Yanam highway. Here, river Gowthami Godavari drains into the Bay of Bengal. Rivulets Coringa and Gaderu intersect in This region. This spreads to about 330 sq km of marsh vegetation. The estuary has a wide variety of mangrove vegetation and fauna.
Mangroves are an important part of a highly productive ecosystem, supplying rich nutrients to the marine life and act as a barrier against the coastal storms. December to February is the breeding season. Major part of the sanctuary is not accessible to the tourists. Normal or speed boat ride up to the mouth of the river is very enjoyable. On either side hundreds of green egrets, might herons, black capped Kingfishers, Red Wattle lapwings and purple herons can be seen. Morning time would be better to watch more birds. Olove Ridley turtles, jackal monkeys, otters and fishing cat are supported.
More migratory birds are flocking in Coringa due to dwindling of mud ponds in Pulicat. Sad part is that Vultures became extinct in the past 20 years.
Beautiful wooden platforms / walkways are provided to have a good look inside the mangrove forest.
Coringa port once played an important role in exporting cotton to England during an American war n 1770.
