I doubt it DQ. Worldwide population is quite small and to get to these guys are extremely difficult. Maybe captive bred and then being released into the wild might be a solution?

Range & population Falco fasciinucha is uncommon to rare throughout its wide range in eastern and southern Africa. Due to variations in observer effort and because 'islands' of suitable rock-face habitat are infrequently visited by ornithologists, the distribution of records is patchy. Its range, distribution and population are therefore poorly known, with probably around 40 known active nest-sites. Despite this, there are probably more than 1,000 mature individuals. It is recorded from southern Ethiopia, south-east Sudan, eastern Uganda, Kenya (may occur at low densities throughout the country), Tanzania (scattered records), eastern Zambia (a few sites), Malawi (two recent records), Zimbabwe (20-50 pairs), Mozambique (one record of unknown reliability), Botswana and north-eastern South Africa (one site).
