Redwing showing characteristics of Icelandic Redwing

A flock of about 200 Starlings were feeding in a field at Hallbankgate, North Cumbria on 4th March.  A little further away at around 150m range some Fieldfares and Redwings moved nervously as they fed on the short grazed turf. One of the Redwings was strikingly more heavily marked on the breast with dense dark streaks which merged to form large dark patches in parts -

There is a brief view of one of the other Redwings behind, showing the much paler overall look and the less heavily streaked breast. 

 This shows one of the paler birds -

   

 Video grabs show the features better.   The putative Icelandic bird Turdus iliacus coburni  shows these features - 

 Darker mantle colour

 More ochre coulour of supercilium 

 More heavily marked under-tail coverts

 Rusty brown legs

In contrast the other Redwings had - 

 Paler mantles with a grey cast

 Whiter supercilia 

 Cleaner under-tail coverts 

 Pale straw coloured legs
