Dear all,
I would like to report to you about the result
of the 2009 International Black-faced Spoonbill Census as
below:
South Korea; 25
Japan: 215
Mainland China and Hainan: 247
Taiwan: 1104
Deep Bay (HK and Shenzhen): 335
Macao: 52
Vietnam: 63
Total: 2041
All the above figures were collected in the
period of 9-11 Jan 2009.
In addition, there were three birds from
Thailand and one from the Philippines outside the census period.
Black-faced Spoonbill
The previous year's census (i.e. 2008) yielded
a total of 2065 birds and so there is a small decrease of
1% to the known world population in this year, the first decrease
since 1998-99. This result also stops the trend with an increasing
rate of about 10% of the world known population.
Taiwan still hold the largest wintering flock
and in fact there has an increase of 7% from the previous
year (2008: 1030 birds). The biggest decrease is coming from
Mainland China and Hainan from 313 birds to 247 birds, i.e.
20% decrease and the Deep Bay area also has a decrease of
9%.
I am not sure the reason of the decrease
of the total world known population figure. We have quite
high coverage in most of the wintering areas, except that
no survey could take place in Jiangsu and Zhejiang (east China)
and Guangxi (south China) in this year but there has not been
reported with big numbers in the past. Dr. Lee Ki- Sup also
thinks that the breeding was quite successful in South Korea
in the summer 2008.
I am grateful to your participation to this
census.
Thank you very much
