Globally it is considered a Least Concern species, due to their reproductive range is relatively wide. Population trends have not been quantified, however it is known that the chicks were caught extensively, and about 5,000 chickens were removed from colonies of Raso and Branco market to be sold as a culinary delicacy, although it is thought that populations are stable. In Mexico is not under any category of protection. Besides poaching to consumption, the chickens are also depredated by gulls and rats; is recommended to conduct studies that assess the impact of these predators on populations of shearwaters.
