Great Shearwater Ardenna gravis



Conservation Status

Globally it is considered a Least Concern species. In Mexico is not considered as a threatened species. Threats for these shearwaters are not well defined, but it is known that in Tristan and Nightingale thousands of adults and about 50,000 chicks are captured annually, which could lead to a significant decline of populations unless sustainable use programs are implemented. The Falklands populations could be exposed to predation by feral cats. The fishing industry may also represent a threat, because the petrels are caught between incidental fauna. Moreover, since nesting colonies are very large, any negative impact could have strong effects on much of the population.
