Demography and Populations


The demography and population biology of the Principe Scops-Owl is still very poorly known, as the species was recently described and the first ecological assessment was published just after.

Population Status


Freitas et al. (2) estimated a population size between 1,149 individuals (95% CI: 813–1,623) and 1,597 individuals (95% CI: 1,007–2,533), considering a suitable area of distribution of 34.4 km2. The authors also noted that as the presence of the owl was not confirmed for all of the distribution, further efforts should be made to improve these estimates. For instance, if it is confirmed that the owl does not occur above 500 m, the population size estimate would drop by over 200 individuals (32).


Population trends have not been estimated, since the only available information on population size was published in 2023 (2), just after the 2022 species description (1).
