6 The International Black-faced Spoonbill Census, 24-26 January
2003 Y.T. Yu The Hong Kong Bird Watching Society Ltd.1 Introduction Black-faced Spoonbill Platalea minor is a globally endangered species (BirdLife International 2000), which only occurs on the east fringe of Asia. Its known world population was less than
1000 individuals (Dahmer and Felley Unpub. MS 2002). Known wintering populations of the Black-faced Spoonbill have been assessed by international census since 1993, with Tom Dahmer as the coordinator. This census was listed as a high priority recommendation in the '
Action Plan for the Black-faced Spoonbill Platalea minor'
(Severinghaus et al. 1995). At the International Black-faced Spoonbill Workshop held in Beijing in 1996, representatives from all range countries agreed to expand upon the census coordinated by Tom Dahmer to gain a wider coverage of the wintering grounds. This census proved to be an effective and practical means to provide information on the population and distribution of wintering Black-faced Spoonbills. The Hong Kong Bird Watching Society (HKBWS), an affiliate of BirdLife International accepted the responsibility to co-ordinate the International Census from
2003 onwards. This note reports on the mid-winter census undertaken in wintering sites 24-26 January 2003. Method The census period was 24,
25 and
26 January 2003. Census dates have always been chosen in mid or late January because the spoonbills seem to be stable in mid-winter. Map
1 shows the area covered by the census. Surveys were carried out in areas where Black-faced Spoonbills had been reported before. Field counts were done in a synchronized manner, making use of binoculars and telescopes.
