Well...you've listed Cardinal twice and there is already a Princess of Cardinals, and a penhen is the female counterpart to a peacock so that one is also covered. Vulture is also on the list. the others would make some interesting princesses so get on it man!
How can this list be complete without the SHRIKE!!!! The little butcher bird. The world's only songbird and raptor! She'll sing you a song, then drop you on barbwire, and rip you to shreds as she feeds.
Most of these made me smile, and I can definitely see myself dipping into this list sometime in the future. The only two who I felt could us a little fleshing out, at least in appearance, were the parakeet and the sparrow. Average NPCs are perfectly acceptable, but it'd be nice to have a little more to use in a game. Go to Comment
Other improvisational weapons/tools:
Icicles are useful as daggers,
Bag Of Holding filled with copper pieces used by chucking the contents at foes, (by strolen)
sleeves make useful garrotes. Ya can't cut anyone's neck, but you sure can choke 'em!
Flaming Logs make great clubs, (any Barbarians out there?)
and Bee hives are very effective when thrown at a mob of enemies. :-)
