Population [top]
Population: Sun et al. (2010) used weather radar to detect flocks of migrating Chinese Sparrowhawk in Taiwan. They estimated that at least 225,935 individuals passed over Taiwan over a period of five days in April 2004. Germi et al. (2009) estimated that at least 350,000 Chinese Sparrowhawk migrate to eastern Indonesia. The population is therefore placed in the band 100,000-499,999 mature individuals.
Trend Justification: Strong declines in local breeding populations in Korea and Japan have been reported (Choi and Nam 2008 in Germi et al. 2009, Kawakami and Higuchi 2003 in Choi et al. 2008).
Current Population Trend: Decreasing
Additional data:
? Number of mature individuals: 100000-499999 ? Continuing decline of mature individuals: Unknown
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
Habitat and Ecology [top]
Threats [top]
Major Threat(s): Land-use change within the speciess wintering range could result in a loss of roosting habitat (Germi et al. 2009). For instance logging operations in Bali may reduce the availability of roost sites (Germi 2005). In Japan and Korea, a loss of nesting resources in secondary forests, particularly around industrial areas has been reported (Choi et al. 2008). Bird strikes from aircraft represent another potential threat (Tang et al. 2008). One Chinese Sparrowhawk was found on sale at a market in Bali however the extent of the trade is unlikely to be significant (Germi and Waluyo 2006).
