Population justification: Ferguson-Lees and Christie (2001) place the population in the band 10,001-100,000. A single roost of 36,000 birds was reported from Senegal in 2008 (Pilard et al. 2011) and a further 10,000 birds at a roost in Mali in 2012 (Buij et al. 2013). In the absence of information from other parts of the range, the population is suspected to be c. 46,000-100,000 birds, roughly equating to 30,000-67,000 mature individuals.

Trend justification: Roadside surveys in Burkina Faso, Mali and Niger from 1969-2004 revealed population declines of 84% in unprotected areas for this species (Thiollay 2006), equating to 47.3% over three generations (11.55 years [Bird et al. 2020]). Numbers in protected areas also declined (by 66% over three generations), but this decline was not statistically significant (Thiollay 2006). Declines of 40-50% from 1973-2000 were also reported in Cameroon (Thiollay 2001), equating to 25.4% over three generations (further surveys of the same routes during 2007-2010 suggested that average encounter rates had increased by 77% since the original surveys, although this result was strongly influenced by a single high count on one transect [R. Buij pers. comm.]). Combining the results of these two studies, weighted by the area occupied by the Scissor-tailed Kite in each country, the species appears to have declined by 5.4% p.a. in West Africa during the 1970s-2000s, equating to 47% when projected over three generations. 

There is very little information available on population trends further east in the species's breeding range or in its wintering range. Declines are thought to be predominantly due to degradation of arid ecosystems and wetland forests resulting from expanding cultivation, woodcutting and overgrazing by livestock (Buij 2013), alongside improved locust control measures and use of pesticides (Ferguson-Lees and Christie 2001). These factors have led to extremely low nesting success in Cameroon (17%) and Senegal (4%) (Buij et al. 2013). As these pressures are ongoing and widespread throughout the Sahel (Walther 2016), it is suspected that population declines are occurring throughout the species’s breeding range. In Kenya, no Scissor-tailed Kites were recorded during road surveys conducted during September-May 1970-1977 (8,659 km surveyed), and only three birds were seen during repeat surveys in 2003-2020 (14,415 km surveyed) (P. Shaw, R. Buij, J. M. Thiollay, S. Thomsett, Z. Cockar and D. Ogada in litt. 2021). 

The species is provisionally suspected to be declining at a rate of 30-49% over three generations. Based on the likelihood that the threats of habitat destruction and degradation will continue, it is suspected that the rates of decline will continue into the future.
