Can you give a wild baby bird a bath?

Alot depends on the age of the bird, usually if it is a baby bird, I will clean it's beak with my fingernail...be careful to keep it's nose clean so it can breathe. I feed them canned dog food mixed with slightly warm water. ....works everytime. DO NOT wet the bird at night, or let it get in a draft....clean it lightly with a washcloth. It is also a good idea to put a desk light on the baby at night...not too close..just enough to warm it. Baby birds need fed often...about every 1/2 hr.... in the beginning you have to hold the bird in your left hand, and insert a very small measuring spoon with the warm food on it into their mouths....after a day or so...they will open wide for the food....they have to understand the process...and lastly..keep an eye on it's *EL BUTTO"....it must be cleaned if it hardens..so it's bowels will work properly....it is a lot of work on these litle guys..but I have saved many.....use paper towels in the bottom of the cage as these absorb waste readily, I also use shredded computer paper for nesting in the bottom of the case...they like that, I have had as many as 3 birds in a cage at a time....and different species....provide climbing sticks or just a small tree branch in the cage...and in a few weeks....they will be climbing up on it!...good luck!
