Adult (3CY+) male Continental Stonechat S. t. rubicola at Beachy Head, East Sussex. July 2011.

Female Continental Stonechat S. t. rubicola at Beachy Head, East Sussex. July 2011.

This female was seen feeding the juvenile male that was accompanying the adult male. It is a very close match to that portrayed in Plate 110 in (Hellstrom and Waern 2011) labelled as a probable female. Some female rubicola are extraordinarily dark, especially in Summer, an effect that becomes more pronounced due to wear, and may result in a rather male-like appearance. Female British Stonechat S. t. hibernans shows no white on sides of neck (Urquhart 2002) and it is interesting to note that the breeding female portrayed on p. 295 therein lacks a white inner-wing covert patch.
