help please (out of area)

as some of you may know i went to scotland this summer. i got my new bird (we have this thing in my family-a new bird every holiday) a redpoll, and lots of them. i was updateing my ticklist last night and it suddenly dawned on me that i didnt know whether these redpolls were mealy or lesser (or arctic). please could somebody help me. i've got some pictures but their not to any great standard. thanks
