Eastern Canary Islands chiffchaff

The eastern Canary Islands chiffchaff or Lanzarote Island chiffchaff (Phylloscopus canariensis exsul) is an extinct subspecies of the Canary Islands chiffchaff endemic to the island of Lanzarote – and possibly also Fuerteventura – in the Canary Islands, Spain. The eastern Canary Islands chiffchaff was more chestnut-backed and shorter-winged than the western Canary Islands chiffchaff, Phylloscopus canariensis canariensis. These birds were formerly considered subspecies of the common chiffchaff but separated due to their morphological, bioacoustical, and mtDNA sequence differences.
