Population justification: The population is suspected to number in the tens of thousands (Ferguson-Lees and Christie 2001).

Trend justification: There have been significant population declines across much of this species's range owing to habitat loss and incidental poisoning/pollution, including Botswana (S. Tyler in litt. 2009; Garbett et al., 2018), Cameroon (Buij and Croes 2014; Thiollay, 2001; R. Buij, unpublished data), Côte d'Ivoire (del Hoyo et al. 1994), Kenya (N. Baker in litt. 2005; Ogada 2009; Ogada et al., 2020 in prep), Namibia (del Hoyo et al. 1994), Nigeria (an estimated decline of at least 50 % in 30 years, now probably only found in Yankari Gam Reserve where it used to be common but only two birds were seen in April and June 2016) (P. Hall in litt. 2005, 2009, 2016, 2020; O. J. Daniel in litt. 2009), Somalia (A. Ajama in litt. 2009), South Africa (Ferguson-Lees and Christie 2001, S. Thomsett in litt. 2005), where the reporting rates between SABAP1 (1987-1992) and SAPAP2 (2007-2020) reduced by 59% (P. Shaw, A. Amar and D. Ogada in litt. 2020), and densities within the Kruger National Park have declined (C. Murn in litt. 2020), Sudan (del Hoyo et al. 1994), Zambia (P. Leonard in litt. 2005), and Zimbabwe (del Hoyo et al. 1994). The overall rate of decline is difficult to quantify but is believed to have been rapid over the past three generations (46 years), placed here in the 50-79% band.
