Common Name/s:
English Black-necked Stilt
Taxonomic Notes:

Himantopus himantopus (del Hoyo et al. 2013) was previously split as H. himantopus, H. leucocephalus, H. mexicanus and H. melanurus following Sibley and Monroe (1990, 1993), contra Christidis and Boles (1994) and Turbott (1990) who included leucocephalus as a subpecies of H. himantopus, but H. melanurus was subsequently lumped with H. mexicanus following AOU (1998) and SACC (2006).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2013-11-01
Assessor/s: BirdLife International
Reviewer/s: Butchart, S.
Facilitator/s: Ekstrom, J., Butchart, S.
Justification:
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
History:
2012 Least Concern
