Given the recent estimated population size (1,600 mature females in 1997, and approximately twice that number in 2007) and the strong observed rate of increase in some well-studied parts of the range, the species, although still scarce relative to its historic abundance, is not considered under threat at the hemispheric level. The population is estimated to be higher now than it was three generations (87 years, assuming a generation time of 29 years; Taylor et al. 2007) ago. Some breeding populations, in particular that off Chile/Peru (see separate listing), are still very small and may need special protection to become re-established.
