In areas of Pakistan where its range overlaps with that of the dusky crag martin, the pale crag martin breeds at a higher altitude. Its range does not overlap there with the Eurasian crag martin, which is found high in the Himalayas, but where both occur in Iran, the pale crag martin favours more arid habitats. In North Africa, the Eurasian species is again found at a higher level. The separation by altitude and aridity means that it is not known whether the closely related "Ptyonoprogne" martins could hybridise. If they were shown to do so, it would cast doubts on their specific distinctness.
