Close by on the other side of Simsang River is the Siju bird sanctuary, a home for many rare and protected birds and other wildlife. The Siberian ducks also migrated here during the winter months. The lesser or Grey Hornbill is also seen around Siju. One interesting and rare bird is the Peacock Pheasant seen in Siju.
Although you can visit any time in the year, November to March is the ideal time to visit Siju Bird Sanctuary where you can come across with many birds migrating from foreign regions.
