Barbary lion In the early 20th century, when Barbary lions were not common anymore, they were sighted in pairs or in small family groups comprising a male and female lion with one or two cubs. Between 1839 and 1942, sightings of wild lions involved solitary animals, pairs and family units. Analysis of these sightings indicate that lions retained living in prides even when under increasing persecution, particularly in the eastern Maghreb. The size of prides was likely similar to prides living in sub-Saharan habitats, whereas the density of the Barbary lion population is considered to have been lower than in moister habitats.

The Barbary falcon is one of the rare cases that may arguably be considered a species under the biological species concept, but certainly not under the phylogenetic species concept rather than the other way around as usual. This case demonstrates that what makes a "species" is not only its descent, but also occurs to a population in the course of evolution, how it adapts, and how this affects its reproductive isolation (or lack thereof) from sister taxa.
