Siberian chiffchaff (Phylloscopus collybita tristis)
Once considered a sub-species of the Chiffchaff the Siberian Chiffchaff is now considered a separate species. The bird is considered rare in the UK but it is believed that it is probably more common than is reported due to the difficulty of establishing the birds identity from the now common wintering Chiffchaff, especially in the South West.
