Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2016
Date Assessed: 2016-10-01

This species has a small population, which is suspected to be declining as a result of habitat loss. The species is likely found in more than one subpopulation and the largest subpopulation likely contains >1,000 mature individuals. Therefore, it is thought to approach the threshold for Vulnerable under criterion C2a(i), and hence is listed as Near Threatened.

Geographic Range [top]

Range Description:Cyornis djampeanus, Tanahjampea Blue-flycatcher, is found only the islands of Tanahjampea and Kalao, Indonesia.

Population [top]

Population:It has been described as common (Clement 2016, J. Eaton in litt. 2016) and is suspected to fall in the range of 1,000-2,500 mature individuals, with the population on Tanajampea suspected to be >1,000 mature individuals. This population size estimate fits with population density estimates for closely related species and the assumption that only a proportion of available habitat is inhabited.

Trend Justification:  The population is suspected to be in decline as a result of continued habitat loss.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:1000-2499Continuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:It is known from closed-canopy forest, and is rarely found in degraded mangroves, if at all (Clement 2016).
Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):3.2
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): The species's habitat is threatened by continued logging on the islands.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway

Conservation Actions ProposedConduct surveys to ascertain more accurate population size and trend estimates. Protect its remaining habitat.
