The Rock Martin inhabits rocky mountains, cliffs, gorges, and wadis. It sticks to mostly arid habitats, such as Wadi Faynan, where it is found flying across the landscape catching insects in mid-flight.

Rock Martins will forage in pairs or small groups and the Bedouin of Wadi Faynan notice them following their goat herds into the mountains, picking off the flies that surround their goats. Rock Martins often construct their nests within buildings and other artificial structures, a process that can take several weeks. Both members of the pair will build the nest out of mud pellets beneath an overhanging rock face or drain.
