Range DescriptionThe species is endemic to Grenada in the Lesser Antilles. Historically, it was more widespread in coastal and possibly offshore islands (B. L. Rusk in litt. 1998), but may always have been rare (Devas 1943). The population declined by c.50% in 1987-1990 (Blockstein 1991), and by 1998 numbered only c. 100 individuals, with strongholds on the Mt Hartman estate, and on the Perseverance and adjacent Woodford estates in the west (Rusk 1998). The population increased to an estimated 182 individuals by 2003-2004, but in 2004 hurricane Ivan had a devastating impact upon the island and the dove's population. This resulted in declines, particularly severe along the west coast, where the population declined from 36 calling males to 3-12 calling males, but also within the Mt Hartman area, from 55 males to 30-48 males (B. L. Rusk in litt. 2005, 2006, 2008, 2010). Three years following hurricane Ivan the population was estimated at 68 calling males with 136 individuals in total (Rusk 2007, B. L. Rusk in litt. 2005), however this assumes an even sex ratio, and there is a tendency for such relict populations to be male-dominated. The total population may therefore be as small as 100 mature individuals or c. 30 reproductive pairs (N. J. Collar in litt. 2008). A survey in 2013 estimated the population to be approximately 160 individuals using distance sampling, with 33 birds recorded (Rivera-Miln et al. 2015). This is equivalent to approximately 110 mature individuals (range 90-130). Of all remaining known territories, 28 are within protected areas, 11 on unprotected crown land and 29 on private land. Forty-three per cent of remaining birds are thought to occur in the Mt Hartman Estate (B. L. Rusk in litt. 2012).
