8 The International Black-faced Spoonbill Census, January 2004 Y.T. Yu The Hong Kong Bird Watching Society Ltd Introduction Black-faced Spoonbill Platalea minor is a globally endangered species due to its small known world population (BirdLife International 2000), which only occurs on the east fringe of Asia. The known world population had been remained only a few hundreds in 1990s (Dahmer and Felley Unpub. MS 2002), but it has been increasing since the commencement of this census and the number firstly reached over 1,000 in January 2003 (Yu 2003). However, large proportion of this population concentrates in only a few places during winter, thus increase the chance that susceptible to some threats such as habitat degradation and destruction, and avian disease. The wintering population of the Black-faced Spoonbills has been assessed by this international census annually since This census was also listed as high priority recommendation by Severinghaus et al. (1995). This census proved to be an effective and practical means to provide annual and comparable information on the population and distribution of wintering Black-faced Spoonbills. The Hong Kong Bird Watching Society, an affiliate of BirdLife International started coordinated the international census from 2003 onwards. This reports covers the on the mid-winter census undertaken in wintering sites January Method The census period was 16, 17 and 18 January 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. Counting of the spoonbills relies on voluntary efforts from counters including experienced bird watchers, researchers and ornithologists. The census results in Hong Kong, Macao, Taiwan, Vietnam and are summarized by coordinators in the respective regions. Taiwanese birdwatchers assisted the count in Vietnam, this year, it - 8 -

9 was conducted by BirdLife Indo-China Programme. The counts in South Korea, China mainland, the Philippines and Thailand were carried out by individuals sending in separate reports. Some sites in close proximity, such as Mai Po in Hong Kong, Futian in Shenzhen and Taipa in Macao, all are in the Pearl River Estuary in southern China. Spoonbills can fly between these sites within a day. Hence, counts in these sites were conducted in synchronization. During the counts, the counters recorded the numbers of the Black-faced Spoonbills, the location and time of the counts at the specified sites. In the previous counts, observers were asked to send in number of immature birds as well. But this may not be easy at sites with many spoonbills (e.g. Taiwan and Hong Kong) or site where experienced observers were not available. The information was then reported to the Coordinator designated by the Hong Kong Bird Watching Society. Results and discussion Overview A record-breaking number of 1,206 Black-faced Spoonbills were counted in this census (Table 1). This is the second year to record over 1,000 individuals after the first time in January 2003 and it is the first time to over 1,200 birds. It has a 13% increase from the count in 2003, it is much higher than 9.3% when we compare the count in 2003 and The known wintering population of the Black-faced Spoonbill has been increasing from early 1990s when this census had begun, except slight drops of number in winter and In addition, the death of 73 Black-faced Spoonbills from avian botulism in Taiwan in winter seems not causing major impact to the growth trend. The actual number can be even higher than this present number because the number in Xuan Thuy, third largest wintering site to the spoonbills, seemed to be under-counted due to unsuitable tides during the census period. The increase of this count was mostly resulted by discovery of new wintering sites in Hainan Island in this census. where a total of 62 birds were seen (c.f. twelve birds were counted in January 2003) and a new highest count of 238 birds in Hong Kong which is in 32% increase from the 179 birds recorded in previous census. A total of 54 sites were surveyed during the winter and forty of these sites - 9 -

10 were found with the wintering Black-faced Spoonbills. Coverage of this census is the highest among other censuses in previous winters comparing to 47 sites in winter and 25 sites in winter and 27 sites in winter More discussions of the numbers and trends of wintering Black-faced Spoonbills in different places are made below. The past data is based on the source from Dahmer and Felley (in prep. and unpublished MS 2002) Hong Kong and Pearl River Estuary A high number of 238 birds were recorded in Mai Po and Deep Bay area during this census, which is the highest count in Hong Kong in this census. This high count was resulted by a high coverage in the whole area and synchronous counts by different teams (Appendix 1). It reflects that this is an effective method to provide a representative figure. Counts in Futian were not fully synchronized during this census due to temporary closure of the reserve. During the census day, the Black-faced Spoonbills were in high mobility and many birds were seen flying around Mai Po and Futian area. Although up to 68 Black-faced Spoonbills were counted (Appendix 2), it is not included in the total number due to possibility of overlapping with that obtained in Mai Po area. The numbers of the Black-faced Spoonbill in Macao were more stable, and a total of 50 birds (Table 3) were recorded in all the counts during the census days. Tainan, Taiwan Chi-ki and nearby Tsengwen Estuary area is the biggest wintering congregation site of this globally endangered species since the discovery of this site in This site also usually holds more than 50% of the known global population. The numbers in this site have been increasing in all censuses in exception of January 1997 (Table 4). In this census, a total of 628 birds (Table 1) were counted constituting 52% of the known population and with an increase of 8% from previous year

11 China Mainland and Hainan Island The number of the Black-faced Spoonbills recorded in China mainland and Hainan shows a fluctuating trend since the commencement of this census (Table 5). One reason is an inconsistent survey effort made in each census. Until now, only a few sites in China could be surveyed in each census. Lack of expertise and resources could also explain this. The number of the wintering Black-faced Spoonbills had been boosted up mainly due to a discovery of large wintering flocks in a total of 61 birds in Hainan Island. Red River Delta, Vietnam Red River Delta has been the third largest wintering site of the Black-faced Spoonbill (Kennerley 1990). Xuan Thuy Nature Reserve usually holds the largest number of the spoonbills in this area and smaller numbers are also present nearby, such as Thai Binh. However, numbers in Xuan Thuy had dropped in the late 1990s (Table 6) due to degradation of both feeding and resting habitats (Yu and Swennen 2001). Situation becomes stable in recent winters (Table 6). This may also be resulted by the general increase of the known world population of this species. Only 15 birds, a relatively low number in recent winters, could be found during this census. An unsuitable tide (i.e. low tide during daytime) during the census days caused few spoonbills loafing in the reserve. A total of 61 birds were recorded in early February and so this number might only be underestimated to the total number of wintering Black-faced Spoonbills in the Red River Delta. had only a few individuals in the beginning of this census but the number is increasing in most of the censuses (Table 7). is the third largest wintering place of this species now. Survey efforts had been improved in past few years that may partly contribute to the increase of the numbers. However, bird watching in has been developed in long time and it seems unlikely that some flocks of the Black-faced Spoonbills could be overlooked in the past. From the above, the increase of the wintering individuals in may actually relate to the population growth of this species

12 Republic of Korea The wintering Black-faced Spoonbills are mainly found in Jeju Island, an island in the south of the Korean Peninsular. Numbers of the Black-faced Spoonbills in the island are fluctuated in a range of 14 to 29 birds since 1990s (Table 8). This is also the northern boundary of the known wintering range of the Black-faced Spoonbill. Thailand Up to three Black-faced Spoonbills were found in Petchaburi province by the Gulf of Thailand in two consecutive winters during the censuses. Together with some records in 1990s, this species may winter in this area in regular basis. The Philippines Three birds were seen in Palawan Island over the winter from December This is the first record of this species in this island. This species is still very rare in the Philippines and last confirm record is also three birds at Batanes Island, northern Philippines from October to December Before that, there was only unconfirmed record dated back to Acknowledgments I would like to thank to all the following counters and data contributors to this census: Dai Nian-hua, Dong Jian-tin, Huang Xiao-jiang, Jiang Hang-dong, Liao Xiao-dong, Liang Wei, Ma Zhi-jun, Su Wen-ba, Wang Hui, Wang Ji-yi, Wang Yong-jun, Xu Meng, Yu Haiyan, Zhong Guo-gang, Zhou Fang, Xiamen Bird Watching Society (China mainland), John Allcock, H.F.
