Kingdom Phylum Class Order Family
Animalia Chordata Aves Passeriformes Motacillidae

Scientific Name: Motacilla alba
Species Authority: Linnaeus, 1758
Regional Assessments:
Common Name(s):
English White Wagtail, Pied Wagtail and White Wagtail
French Bergeronnette grise
Taxonomic Source(s): Christidis, L. and Boles, W.E. 2008. Systematics and taxonomy of Australian birds. CSIRO Publishing, Collingwood, Australia.
Taxonomic Notes: Motacilla alba and M. lugens (Sibley and Monroe 1990, 1993) have been lumped into M. alba following AOU (2005). Motacilla alba (Sibley and Monroe 1990, 1993) was split by Sangster et al. (1998) into M. alba, M. alboides, M. baicalensis, M. leucopsis, M. ocularis, M. personata and M. subpersonata but this treatment is not followed by the BirdLife Taxonomic Working Group because no vocal, morphological or phylogenetic evidence is provided by Sangster et al. (1998) and Alström et al. (2003) notes that all contiguously distributed subspecies of M. alba interbreed. Sibley and Monroe (1990, 1993) and Sangster et al. (1998) also split M. lugens from M. alba but these taxa are also lumped following AOU (2005).

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2014
Date Assessed: 2014-07-24
Assessor(s): BirdLife International
Reviewer(s): Butchart, S.
Facilitator/Compiler(s): Butchart, S., Ekstrom, J., Symes, A. & Temple, H.
This species has a very 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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely 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.

Population [top]

Population: Rich et al. (2004) estimated the global population to number 200,000 individuals. In Europe, the breeding population is estimated to number 13000000-26000000 breeding pairs, equating to 39000000-78000000 individuals (BirdLife International 2004). Europe forms 5-24% of the global range, so a very preliminary estimate of the global population size is 163000000-1560000000 individuals, although further validation of this estimate is needed.

Trend Justification:  In Europe the overall trend from 1980-2011 was stable, based on provisional data for 27 countries from the Pan-European Common Bird Monitoring Scheme (EBCC/RSPB/BirdLife/Statistics Netherlands).
Current Population Trend: Stable
Additional data:
Number of mature individuals: 50000000-500000000 Continuing decline of mature individuals: Unknown
Extreme fluctuations: No Population severely fragmented: No
Continuing decline in subpopulations: Unknown
Extreme fluctuations in subpopulations: No All individuals in one subpopulation: No
