Population [top]
Population: The global population size has not been quantified, though in Europe, the breeding population is estimated to number 10-100 pairs, which equates to 20-200 mature individuals (BirdLife International 2015), with Europe forming <5% of the global range. National population sizes have been estimated at c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in China and c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009).
Trend Justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats. The tiny European population size trend is unknown (BirdLife International 2015).
Current Population Trend: Stable
Additional data:
? Number of mature individuals: Unknown ? 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
Habitat and Ecology [top]
Habitat and Ecology: In the breeding season this species inhabits bushy tundra and taiga swamps with tall dense sedges, reeds, shrubs and even trees, in the zone between tundra to the north (inhabited by Anthus cervinus) and taiga forest to the south (inhabited by Anthus hodgsoni). It breeds from late June to July in Siberia. The nest is a cup of grass and other leaves, lined with finer material and built on the ground in low vegetation or in the shelter of a tuft of grass. Clutches are generally four to five eggs (Tyler 2016). It feeds mainly on invertebrates. The species is migratory and the wintering range is poorly known (Tyler 2016).
Systems: Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat: Unknown
Generation Length (years): 3.7
Movement patterns: Full Migrant
Threats [top]
Major Threat(s): There is no evidence for any recent contraction of range or population decline (Tyler 2016).
Conservation Actions [top]
Conservation Actions: Conservation Actions Underway
Bern Convention Appendix II. There are currently no known conservation measures for this species within its European range.
Conservation Actions Proposed
As little is known about this species’s requirements and populations status, it would benefit from more research, surveying and monitoring.
Amended [top]
Amended reason: Map revised.
