4. Keep the bird warm, quiet, and in a dark environment
5. Lots of tender loving care

Always see the vet first for tests and then start by carefully going through his diet to make sure that he is getting the things he needs… fruit, vegetables, cereal, nuts, seeds, and sprouts.
If pesticides have been sprayed move the bird as far away as you can, even taking it to a friends home till the danger is over, best not to spray anything near to your bird.Heavy metal poisoning can come from a recently fixed bird cage, be careful with welding and painting.
Infections can be cured with antibiotics, always follow the vets treatment and finish the course.
Head injuries come with their own problems, find out if it will heal with time and patience and special nursing..
If it cant and the bird is severely injured think about doing the kindest thing and putting the bird to sleep.. This is a last resort !

Remember the all important tender loving care, warmth, love, quiet, darkened area, good food, clean drinking water..
Put a pillow in the bottom of the cage if need be, and lower the perches and food dishes..
