Adult male Redpoll spp.

This adult male bird has a wing length (74mm) which is only 0.5mm outside the maximum range of Lesser Redpoll but is 4mm within the range of Common Redpoll, therefore possibily suggesting it is a Common Redpoll. However, it is a rather brown backed individual with brown wingbars and a largely brown rump suggesting Lesser Redpoll. Just to add more confusion, some Common Redpolls can be brown, so without a definitive wing length approaching the maximum of Common (say 78mm) then probably best not to speculate. Mmmm.
