This unobtrusive species qualifies as Vulnerable because it has a small and naturally fragmented range and population, which is likely to be declining owing to habitat loss at the lower fringes of its altitudinal range.

Geographic Range [top]

Range Description: Cochoa azurea is endemic to the mountains of west and central Java, Indonesia, where it is known from the higher peaks within a range spanning from Gunung Halimun to Gunung Slamet. There are recent records from just four localities. It appears to occur at low densities, although it is perhaps more unobtrusive than genuinely rare. Its population is nevertheless likely to be undergoing a steady decline as Javan montane forests become increasingly isolated by deforestation on lower slopes.

Population [top]

Population: The population size is preliminarily estimated to fall into the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits montane rain forest between 900 and 3,000 m, where it is rather tame, moving quietly or sitting motionless for long periods, often in the lower and middle storeys, but also in the canopy. It is presumed to be largely sedentary, but may make local seasonal movements.

Systems: Terrestrial

Threats [top]

Major Threat(s): Forest loss, degradation and fragmentation, through widespread agricultural encroachment and localised development (e.g. holiday resorts and geothermal projects), is becoming an increasing threat in the lower altitudinal range of the species (900 m -1,500 m). The area above this zone is still relatively secure (N. Brickle in litt. 2012). It has also been recorded the domestic bird trade, albeit in very small numbers (N. Brickle in litt. 2007).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
It occurs in two protected areas, Gunung Gede/Pangrango National Park and Gunung Halimun Nature Reserve (now Gunung Halimun-Salak National Park), both of which provide hope for a range of threatened species endemic to Java. The two areas cover over 500 km2 of forest between 500 m and 3,000 m. A substantial nature reserve has been proposed for Gunung Slamet (an historical site for the species), and a small nature reserve exists on Gunung Tangkuban Prahu, from where there are also historical records.

Conservation Actions Proposed
Conduct further surveys for the species at all mountains potentially within its range to clarify its current distribution and population status. Propose key sites for establishment as protected areas, or as extensions to existing reserves. Cooperate with local authorities and relevant companies to minimise the impact of tourism and development projects on forested mountains within its range.
