We're in danger of becoming a bit blase about Waxwings, but boy aren't they superb. More on the excellent Mid Wales Ringers site here - http://midwalesringers.blogspot.co.uk/
Beautiful in the hand a surprisingly large birds.
The undertail coverts are a superb rusty red colour. I keep checking for one that has got plain undertail coverts - you never know ;-)
The small Waxy tips and lemony yellow on this bird show it to be a female.
