Population justification: The global population is estimated at well over 10,000 pairs which equates to 20,000 mature individuals (Thiollay 2000). The species is reported to be generally common and locally abundant in some areas (Ferguson-Lees & Christie 2001), outnumbering all other raptors except Black Kite Milvus migrans (Thiollay 2000). It is placed in the band 20,000-49,999 mature individuals.
Trend justification: The population is suspected to be in decline locally owing to over-grazing and drought (Ferguson-Lees and Christie 2001). A decline in non-breeding visitors to Kenya has been observed (Thiollay 2000). A decline in individuals counted during the dry season was also observed in Burkina Faso, Mali and Niger during 1969-2004, although it should be noted that this may be due to differences in the timing of migration between years rather than a population decline (Thiollay 2006).
