Taiwan lies on a major migration route for the gray-faced buzzard hawks, also known as gray-faced vulture or south-flying eagles. With an average of 20,000 gray-faced buzzard hawks expected to transit through Taiwan each year.

On Saturday, March 20 at 9.00am in Baguashan Mountain Range Visitors Center, Changhua City Guashan Rd. # 13 – 7, tour guides volunteer to introduce visitors to the migrating hawks. Free shuttle buses are arranged from Changhua City Train Station, 8.00am – 4.00pm.
