In the January issue of the BOU’s journal Ibis, the BOU Records Committee’s Taxonomic-subcommittee present their latest taxonomic recommendations for Western Palearctic birds.

The items are summarised below, but for full details of each item please see the full paper. View paper (free to view from 24 Nov) (Sangster et al. 2014).
 

Newly recognized species

The status of species on the British List is indicated by their category (e.g. Category A).
 
Ostrich Struthio camelus to be treated as two species:
• Common Ostrich Struthio camelus (recorded in the Western Palearctic)
• Somali Ostrich Struthio molybdophanes (extralimital)
 
Shy Albatross Thalassarche cauta to be treated as three species:
• Shy Albatross Thalassarche cauta (recorded in the Western Palearctic)

• Sakhalin Leaf Warbler Phylloscopus borealoides (extralimital)
(A warbler photographed at Southwell, Portland, Dorset, on 22 October 2012 has been accepted by BOURC as either Phylloscopus tenellipes or P. borealoides)

New superfamily

Penduline tits (Remizidae) and tits (Paridae) are removed from Sylvioidea and placed in their own superfamily, Paroidea, based on new information about their evolutionary relationships.
 

Taxonomic sequence

The taxonomic sequence of the species of larks (Alaudidae) and accentors (Prunellidae) is revised based on new insights into their evolutionary relationships.
 

Generic changes

Note the new generic names.
