If you have found a hatchling or young nestling that is warm, has a smooth abdomen, seems energetic, balanced and uninjured, it can be renested (returned to the nest). Renesting takes one of three forms - placing the bird back in the original nest; placing a fallen nest in a suitable container, attaching it to a tree, then putting the bird in it; or making a substitute nest, attaching that to a tree and placing the bird in that. (see next page for examples)
	Never place a naked or partly naked bird in a substitute nest if there are siblings in the original nest. Parents can feed their young in more than one nest but can only keep one nest warm. In addition, any attempts at renesting must be done with several hours of sunlight. After renesting, watch for one or two hours to see if the parents return. If they don't, the bird must be brought inside. It's a good idea to contact a rehabilitator early in this process so that you know what to do if the renesting attempt fails.
	When you find a naked or partly naked bird, observe for a short time to see if parents are around, then put it in a warming box while you decide what to do next. One way to create a warming box is to use a shoebox with holes in the lid. Inside the box place two disposable gloves partly filled with very warm water and tied (like water balloons), placing one on either end of the box. In the middle place a tissue nest made by wrapping toilet paper around your fist. (DO NOT use green plant material for a nest - it will chill the bird.) Instead of the gloves, you might use four zip-lock bags. Fill one with very warm water, close, and then zip it inside a second one to help avoid leaks. Place one double bag on either side of the tissue nest, not directly in contact with the bird. Put the nestling in the nest and place the box in a quiet, protected location. Now is a good time to try contacting a rehabilitator.
