Population justification: Status and trends of the population are very poorly known. An average of 14,320 (minimum: 5,452 [2010], maximum: 28,254 [2016]) Japanese Sparrowhawks were counted migrating over Khao Dinsor, Thailand between 2010 and 2016. The population is roughly estimated to number in the tens of thousands to 100,000 individuals, based primarily on counts of migrants in Indonesia (Ferguson-Lees and Christie 2001). Assuming a total of 20,000-100,000 individuals, the number of mature individuals is 13,400-67,000.

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
