Update - 9 January 2013: After studying and learning about redpoll subspecies classification (given the current state of knowledge), my assessments of these photos are as follows:
A-flammea/exilipes..........G-flammea/exilipes..........M-flammea/exilipes
B-flammea/exilipes..........H-flammea/exilipes..........N-flammea/exilipes
C-flammea/exilipes..........I-flammea...................O-flammea/exilipes
D-flammea...................J-flammea/exilipes..........P-exilipes
E-exilipes..................K-flammea/exilipes..........Q-flammea/exilipes
F-flammea...................L-flammea...................R-exilipes

Numerically:
exilipes -- 3/18 (17%)
flammea -- 4/18 (22%)
indeterminate -- 11/18 (61%)
