Summarize the following:
Walk towards the fledgling until you’re less than 3 feet (0.91 m) away. Crouch down and inspect the young bird for any signs of injury. These can include a drooping wing, visible broken bones, or any signs of blood. Also watch the bird as it moves. If it holds its wings against its sides and doesn’t show signs of pain, it’s probably not injured. A seriously injured fledgling may have flies buzzing around or, if it’s in very bad shape, have a few maggots crawling across its body. Wildlife rehabilitators are trained professionals who know how to care for orphaned or hurt fledglings. Also call a rehabilitator if the fledgling doesn’t seem to be injured but appears to have been abandoned by its parents. The rehabilitator will inspect the fledgling and, if needed, can take the bird to a wildlife care center.  If you live in the United States, you can find a website for wildlife rehabilitators in every state online at: https://secure.mediapeta.com/peta/PDF/WildlifeRehabilitatorsbyState.pdf. If you live outside of the U.S., contact your local government or animal-control center and ask about wildlife rehabilitation personnel. In some situations, you won’t have time to wait for a wildlife rehabilitator to arrive on the scene. For example, if feral cats live in the area where the fledgling has fallen or if you see a hawks circling, the fledgling is in immediate danger. Gently slide your hand beneath the fledgling, lift it up, and place the fledgling onto a low tree branch or sturdy bush. It’s a good idea to still call a wildlife rehabilitator after you’ve placed the fledgling into a tree. Domesticated animals can be dangerous to fledgling birds that are unable to fly. Housecats especially would enjoy toying with and eventually killing a defenseless fledgling. So, if the fledgling is within 1⁄4 mile (0.40 km) of your home, keep all pets indoors for up to 2 weeks, or until the fledgling has flown off. If you have neighbors with housecats, advise them to keep their pets indoors for the same amount of time also.

Summary:
Inspect the fledgling to determine whether it’s injured. Call a wildlife rehabilitator if a fledgling is injured. Place a fledgling on a low tree branch if it’s in immediate danger. Keep housecats and other pets indoors until the fledgling moves off.
