Notes Johanseni was considered no longer valid in WPE4 based on Burgers et al. (1991 Ardea 79: 307–316) , Sangster and Oreel (1996 Dutch Birding 18: 310-316) and Heinicke (2008 Casarca 11: 53-75 and 2009 Wildfowl 59: 77–99) all questioned the validity of subspecies johanseni and Ruokonen and Aarvak (2011 Molecular Phylogenetics and Evolution 48: 554–562) found no support for its existence using mDNA analysis. Besides the genetic basis, there is also strong morphological and ecological evidence that Bean Geese breeding in western Siberian taiga belong to subspecies fabalis (e.g. Burgers et al. 1991, Mooij and Zöckler 1999 Casarca 5: 103–120, Heinicke 2009). Instead a separate population of fabalis considered to winter in Central Asia and this view is adopted in the AEWA SSAP for Taiga Bean Goose. However. A. f. johanseni is still recognised by the HBW/BirdLife International, the taxonomic reference of AEWA, and other global authorities such as Clements 6th edition (version 6.9 incl. 2014 revisions), Howard and Moore 4th edition and IOC World Bird Names, version 4.04.

Notes

  • S3944 - 312 describes a small, geographically isolated wintering population and casts doubt on the validity of johanseni which was previously considered to be the form wintering in this area.
  • S7763 - Practically disappeared as winter visitor in Kyrgyzstan, no large numbers reported since mid-2000s.
  • S8270 - Practically disappeared as winter visitor in Kyrgyzstan, no large numbers reported since mid-2000s.
  • S9114 - Practically disappeared as winter visitor in Kyrgyzstan, no large numbers reported since mid-2000s.
  • S9184 - Practically disappeared as winter visitor in Kyrgyzstan, no large numbers reported since mid-2000s. However, satellite tagging shows that the bulk of the population may winter further east. 933 individuals were counted on migration in 2014 (Rozenfeld et al., 2018).
