A late Common Whitethroat in the Beachy Head Hotel Garden
Whilst we considered the above individual didn't look out of the ordinary for communis any late Autumn Common Whitethroats are worthy of scutiny:
Eastern races of Common Whitethroat are not on the British List. Both icterops and rubicola may be identifiable owing to their cold, grey plumage tones (with greatly reduced rufous tones on the wings), while biometrics and moult strategy may offer some support. However, it is unclear whether volgensis, which forms a clinal bridge between the familiar communis and eastern rubicola may resemble icterops and rubicola in certain key characters. Consequently a ringing recovery from breeding birds seems the only way to be certain of racial origin at present. (Racial identification and assessment in Britain: a report from the RIACT subcommittee BB 99 December 2006 619 -645).
