Justification of Red List category

This species is classified as Endangered because it is restricted to a small breeding range in which severe storms in the 1980s resulted in a decrease in habitat quality and poor breeding success. Based on this low breeding success, the population is estimated and projected to be undergoing a very rapid decline over three generations. Evidence suggests that the number of breeding pairs may have remained relatively stable; thus, the species might qualify for downlisting in the future. However, in the absence of recent substantive data upon which to assess trends or changes in productivity rates, projected declines are maintained as a precautionary measure.
