Population justification: The population size has not been quantified. In Angola, recent surveys found it to be relatively rare (Cáceres et al. 2015), while other studies found it more widespread and at least locally very common (Mills and Dean 2007, Mills 2010). A preliminary estimate can be derived based on the population estimate of the closely related Bokmakierie (Telophorus zeylonus), which occurs in a much larger global range, is described as ‘not uncommon’ in Angola and estimated to number 670-6,700 mature individuals (Dean 2000, BirdLife International 2019, see also eBird 2019). Unless more detailed information becomes available, we can tentatively assume Monteiro’s Bush-shrike to have a similar population size, however given that Monteiro’s Bush-shrike has been described as locally very common, it is considered unlikely to have a population smaller than 1,000 mature individuals. The population is therefore tentatively placed in the band 1,000-6,700 mature individuals.
Trend justification: Monteiro’s Bush-shrike is suspected to be in decline due to the ongoing destruction of its habitat. Considerable forest loss has occurred on the Angolan scarp already in the last decades. The major driver of forest loss is the conversion of forests into agricultural land by subsistence farmers. Canopy trees and forest undergrowth, but also overgrown coffee plantations and secondary growth have been removed to give way for cultivations of banana, manioc, sweet potatoes, cassava and maize (W. R. J. Dean in litt. 1999, F. Olmos in litt. 2011, M. Mills in litt. 2019).
