Population justification: D. Wiedenfield (in litt. 2004) considers the population likely to number fewer than 1,000 individuals, and possibly even fewer than 200. A. Tye (in litt. 2005) estimates the population to number c.600 individuals. Wiedenfield and Jiménez-Uzcátegui (2008) consider it likely to number much fewer than 500 individuals. It is placed in the band 250-999 mature individuals here, equating to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.
Trend justification: Current population trends are unclear, but historical declines are probably continuing (A. Tye in litt. 2005, D. Wiedenfeld in litt. 2005, 2007, 2011, 2012, Wiedenfeld & Jiménez-Uzcátegui 2008, T. de Vries in litt. 2012, P. Grant in litt. 2012). Minimum counts of birds observed at Daphne Major Island since the 1970s indicate a decline here (P. Grant in litt. 2012).
