This species is known only from two locations within a very small range, where its specialised habitat is very restricted and declining. It is listed as Endangered because habitat loss and degradation is almost certainly now impacting the known location.

Previously published Red List assessments:
2008 Endangered (EN)
2006 Endangered (EN)
2004 Endangered (EN)
2000 Vulnerable (VU)
1994 Lower Risk/near threatened (LR/nt)
1988 Near Threatened (NT)

Geographic Range [top]

Range Description: Metallura iracunda occurs on the cerros Tres Tetas, Viruela, Pintado and Tetari, and probably Sabana Rubia, in the Sierra de Perijá on the border of Colombia (Guajira) and Venezuela (Zulia) (Meyer de Schauensee 1978, Fjeldså and Krabbe 1990, A. Viloria per J. Fjeldså in litt. 1998, Hilty 2003).

Population [top]

Population: The population is estimated to number 20,000-49,999 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size (e.g. the lower quartile of such estimates spans 50-130 individuals per km2) and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied.

Trend Justification:  Although there is very little information from its range, this species's population is suspected to be declining at a slow to moderate rate, in line with habitat loss and degradation.
Current Population Trend: Decreasing
Additional data:
Continuing decline of mature individuals: Unknown
Extreme fluctuations: No Population severely fragmented: No
No. of subpopulations: 2 Continuing decline in subpopulations: Unknown
Extreme fluctuations in subpopulations: No All individuals in one subpopulation: No
No. of individuals in largest subpopulation: 1-89

Habitat and Ecology [top]

Habitat and Ecology: It inhabits small areas of open páramo vegetation near summits (A. Viloria per J. Fjeldså in litt. 1998). Cerro Pintado comprises karstic limestone covered by elfin forest, Swallenochloa bamboo and grass páramo (A. Viloria per J. Fjeldså in litt. 1998). Cerro Tetari is sandstone and supports a different type of páramo vegetation (A. Viloria per J. Fjeldså in litt. 1998). It occurs at elevations of 2,800-3,200 m (A. Viloria per J. Fjeldså in litt. 1998), but as low as 1,850 m in Venezuela (Meyer de Schauensee 1978, Hilty 2003, Sharpe and Lentino 2008).

Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 4.2
Movement patterns: Not a Migrant

Threats [top]

Major Threat(s): Habitat on the lower slopes of the Sierra de Perijá is severely threatened by narcotics cultivation, uncontrolled colonisation, cattle-ranching and mineral exploitation, which are all facilitated by the many roads approaching the sierra from the Colombian side (C. J. Sharpe in litt. 1997, 2000, A. Viloria per J. Fjeldså in litt. 1998, R. Strewe in litt. 2003, Sharpe and Lentino 2008). However, Cerro Tetari remains as yet unaffected by these developments (A. Viloria per J. Fjeldså in litt. 1998). Only patches of montane forest remain on the steepest slopes of the Cerro Pintado (R. Strewe in litt. 2003). Forest is still being lost to burning and poppy cultivation. Security problems make access very difficult (R. Strewe in litt. 2003).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
CITES Appendix II. Cerro Tetari is formally protected by Sierra de Perijá National Park, Venezuela, but there is no active management (Rodríguez and Rojas-Suárez 1995, A. Viloria per J. Fjeldså in litt. 1998). Cerro Pintado lies to the north of the park, but the inhabitants of the Villanueva village, Colombia, attempt to protect the natural habitat (A. Viloria per J. Fjeldså in litt. 1998).

Conservation Actions Proposed
Estimate the population size (C. J. Sharpe in litt. 1997, 2000, P. G. W. Salaman in litt. 1999, Sharpe and Lentino 2008). Study its ecological requirements (C. J. Sharpe in litt. 1997, 2000, P. G. W. Salaman in litt. 1999, Sharpe and Lentino 2008). Assess habitat availability using aerial photographs (C. J. Sharpe in litt. 1997, 2000, Sharpe and Lentino 2008). Manage and effectively protect Sierra de Perijá National Park (Rodríguez and Rojas-Suárez 1995, Sharpe and Lentino 2008).
