Here's what to do, according to
Project Wildlife:
- If you find an injured or orphaned hummingbird on the ground, lift it along with the material it is sitting on, and place it on crumpled tissue in a small box with holes in the lid.
- Always use tissue or paper towels, NOT cloth. The bird's feet may become entangled in the cloth. Provide the bird with a low heat source, but be careful not to overheat the bird. If it starts open-mouth breathing or its neck is outstretched, it is too hot.
- Hummingbirds can die within four hours if not fed. Offer adult hummers a sugar water mixture of 1 part sugar to four parts water. Hummingbird babies that are fed sugar water or commercial hummingbird nectar for more than 24 hours may develop crippling deformities.
