Range DescriptionPtilinopus layardi is endemic to the islands of Kadavu and neighbouring Ono in south-west Fiji. In 2000, surveys found this species to be common in evergreen forests, with 53 birds recorded (mostly calling males) in 23.5 hours in a mixed lowland and montane site, and 17 birds in 15 hours at a montane site (G. Dutson in litt. 2005), equating to 23 birds/km2 and 11 birds/km2 at these sites respectively, mostly calling males. There are a number of likely errors in this estimate, especially the number of silent birds overlooked and the species's higher abundance at lower altitudes (where calling males can be as little as 100 m apart (G. Dutson in litt. 2005). The area of dense and medium-dense forest on Kadavu is around 225 km2 (National Forest Inventory 1990-1993), suggesting that the total population is around 10,000 birds. However, the species also occurs on the island of Ono which probably constitutes a second sub-population (as this and other Chrysoenas doves are rarely seen flying outside forest and have not been recorded from smaller islands), numbering about 5% of the total population (G. Dutson in litt. 2005).
