Distribution Black-faced Spoonbill is a migratory bird which breeds in the temperate region during summer. It migrates south to subtropical and tropical regions in autumn and winter, then returns to the northern breeding sites in early spring. The only confirmed breeding grounds are the island at Changshan Qundao, off the coast of Liaoning Province of China, and isles located at the Demilitarized Zone west of the Korean Peninsula. The three major known wintering grounds of Black-faced Spoonbill are Tsengwen estuary in Taiwan, Mai Po Inner Deep Bay in Hong Kong, and the Red River delta in Vietnam. Other wintering sites are located at the coastal areas of Macau SAR, Fujian, Guangdong, Guangxi and Hainan Provinces. South Korea and Japan have also been found hosting a small wintering population. The situation along the coasts of China and Vietnam is still poorly known. The Black-faced Spoonbills in Hong Kong are commonly seen around Mai Po Innner Deep Bay areas including Mai Po Nature Reserve, Tsim Bei Tsui and Pak Nai. Sometimes they are found feeding at the fishponds in San Tin and Lok Ma Chau. Other records away from Deep Bay include Tai Lam Chung, Tai Po, Cheung Chau and Starling Inlets. The resting sites of Black-faced Spoonbills are mainly restricted to shrimp ponds, gei wais in Mai Po Nature Reserve. Sometimes the whole flock is gathered at a single location. Migration Route Black-faced Spoonbill is a migratory species. Every early spring in March, they leave the wintering sites and head north to accomplish the most crucial mission in their life - breeding. In October they return to their wintering ground. This life cycle repeats year after year. However, we still don't know much about their long migration routes. Where do they rest during their tiring journey? Do they follow the same route when heading to breeding and wintering grounds? In order to find out the answers to these questions, ornithologists from Hong Kong and Taiwan collaborated with Japanese researchers to carry out the first satellite tracking of this bird species in the winter of 1997. They were first found moving from Tsengwen estuary to the estuary of Ao Jiang River in early May 1998, and then located at Xiangshan Gang bay in mid-May 1998, but then the signal ceased. Satellite tracking was performed the following year: 4 birds from the Tsengwen estuary moved to northern Taiwan and onwards to the coast of northern Fujian. These birds, together with the 6 birds tracked from Mai Po in Hong Kong, which traveled northwards along the coast of eastern China and then reached Zhejiang, flew northward through the coastal areas of Fujian, Zhejiang and Jiangsu provinces. They finally arrived at the islets in the Demilitarized Zone on the west coast of the Korean Peninsula. This is the first time that researchers have successfully tracked the migration of Black-faced Spoonbill, which signifies a break-through in learning more about the mysterious aspects of this endangered
