The Chaffinch in winter– Chaffinches, which were on the rise, suffered set-backs in 2006, due to the prevalence of Finch trichomonosis, but they are still a widespread bird, with backs patterned to help their camouflage as they feed, mainly hopping along on the ground. In winter our numbers are swelled by migration, but Chaffinches are on of the species which practice “differential migration”, the females and juveniles travelling further south, probably  showing males fare better in harsher conditions, and meaning you are likely to see either more males or more females in your patch in winter. The head markings on the males, as you can see, are dull grey-brown in winter, and though you might assume they get their blue, breeding colouring by moulting, they don’t- the feather-tips gradually wear away to reveal the bright caps. Conditions: A dry spell with gentle breezes and sunny intervals. Temperature: Max 11 Min 7 C.
