Population justification: Several hundred pairs were estimated in 1975 by Holyoak and Thibault (1984), and 500-1,250 pairs were estimated in 1998, at a mean density of 2-5 pairs/ha (Thibault and Meyer 2001). This equates to 1,000-2,500 mature individuals, placed here in the band 1,000-2,499 mature individuals.

Trend justification: The population is estimated to be stable, based on survey data.
