Class: AVES
Order: FALCONIFORMES
Family: CATHARTIDAE
Common Name/s: TURKEY VULTURE (Eng)

Assessment Information

Red List Category & Criteria: LC    ver 3.1 (2001)
Year Assessed: 2004
Assessor/s: BirdLife International
Evaluator/s: Ekstrom, J. & Butchart, S. (BirdLife International Red List Authority)
Justification: This species has a large range, with an estimated global extent of occurrence of 28,000,000 km². It has a large global population estimated to be 4,500,000 individuals (Rich et al. 2003). Global population trends have not been quantified, but populations appear to be stable (Ferguson-Lees et al. 2001) so the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
History:
1988-Lower Risk/least concern (BirdLife International 2004)
1994-Lower Risk/least concern (BirdLife International 2004)
2000-Lower Risk/least concern (BirdLife International 2000)
