Population justification: The population was estimated at c.1000 individuals in 2007, roughly equivalent to 670 mature individuals.
Trend justification: Surveys of breeding territories indicate that density of territorial pairs roughly halved between 1990 and 2007, owing to predation by mice (Ryan & Cuthbert 2008).
