Looks like a nasty injury there with cuts on the head. How is your bird behaving right now? Does it seem to be in shock or stressed? I took a quick look and found this: Though, for the time being I would want to treat for shock if your bird is behaving as in puffed up with eyes closed.. and where are you located?
Treat for Shock
Birds that are in shock appear weak, unresponsive, fluffed up and breathe in slowly and out quickly. Place the bird in a quiet, semi-dark, warm, humid environment. Warmth is essential – temperature should be between 25 and 30 degrees ( 80-85 degrees Fahrenheit) . Place a clean cloth or some newspaper in the bottom, which is laid out flat. A hot water bottle can be filled with hot water from the tap and wrapped in a slightly damp cloth, which is placed near the bird. The bird will take 4 to 6 hours to recover from shock – if it doesn’t – seek advice. While the bird is in shock, don’t force it to eat or drink.
When the Bird has recovered from Shock
Visually examine the bird
Stand a short distance away and examine the bird visually. Look for any deformity, unusual wing positions or lameness.
Note the following:
- Eyes – should be both open and bright. Pupils should be equal in size. Unequal pupil size may indicate head trauma. If eyes are partly closed then the bird is unwell. One eye closed may mean an injury or infection. Check to see if the bird responds to the movement of your hand.
- Head – head nodding, head tilting and periods of eye closing can indicate severe illness or trauma.
- Breathing – a healthy bird’s breathing is hard to detect.
- Cuts and Wounds
Cuts and wounds can be gently cleaned with a dilute solution ( 50% water-50%) of antiseptic such as Savlon or Hydrogen Peroxide 1% or a solution of warm salt water. Don’t remove any clots of blood as this can start the bleeding again.
