Hi Wolfbirder.
It has an obvious white rump, but that's about it tbh.
It's head was typically flammea (obvious contrasty ear coverts, and lacking that small-billed appearance exilipes can often show when relaxed), the upperpart ground colour was that 'mealy brown' as oppose to that lighter sandy/buffy brown you would expect for most 1st yr exilipes......... Oh.... and it had 2 thick arrowheads on the UTCs too !
I'm no expert but I assume this bird is probably a 1st year male flammea. It shows the white rump (with a few streaks/flecks) and reduced flank streaking suggesting a male, but is lacking the red that you might expect to see on adult males.
If you want a redpoll to properly mess with your head, check out the structure on this thing ! Taken at Rainton a couple of weeks ago.
