Throw a rock or chunk of ice to distract it then sneak behind it and try to get a stab in.
The bird goes over to the rock thinking it might be prey, then you come out and stab it, but the bird quickly flies out of reach before you hit it. It now turns back and is heading to attack. (I was surprised by this, but the dice rolled a 12, which meant a deadly blow.) It strikes before you can react and punctures deep nails into your chest and pecks at your face. It jabs your eye and suddenly your vision is limited (sorry for the gore, but hey, it's the hunger games). The odds have not been in your favour, the bird crawls further up your chest until it's nails are nearly up to your heart. With incredible luck, you throw the bird of your chest and stab it. You survived this, but are horribly injured.
You are sick from freezing, badly injured, and an eye is damaged beyond recovery.
Use feathers from the wounds to try to stop up the bleeding by filling the bleeding areas with feathers. They may work as improvised bandages. Can you still manage to climb a tree?
You use the feathers from the bird to block the wounds, they work fairly well, not great, but better than nothing. You can still climb a tree, the wounds are nowhere in your legs or arms, it just may take a while.
WASH THE WOUNDS AGAIN AND APPLY NEW FEATHERS TO PREVENT INFECTIONS. AND HIDE UP IN THE LEAVES WHERE IT IS WARMER.
I flipped a coin to see what you do BTW.
Out of desperation you light a fire to keep warm, but attract some other tributes. You hear them coming, they will be here soon. It sounds like these might be the Careers.
Current Conditions: Bad wounds freshly cleaned, and a dead eye.
