Ya call a wild life centre,

You can give him.

1 Boiled Egg.

1 Regular Tums.

Some Apple Sauce.

Soaked Dog food.

Mix it all together and feed it to the bird with a stick, careful to not get it in it's air way.

If your scared of that .. phone a wild life centre asap, keep the bird in a box with a warm blanky.

Good luck!
