Don’t be too eager to rescue a fully feathered young bird (fledgling) that can’t quite fly.
Fledglings have short tails and are completely feathered with no bald spots. They can hop but not fly well. When the fledgling first leaves the nest they may still be on the ground with mom and dad feeding them for a few days until they can fly. If you find a fledgling that is in a dangerous place: e.g. beside a busy road or in a dog fence, you can move it to a nearby shrub or to the other side of the fence. Try and keep this distance no more than 20-30 feet and the parents will find them. Do not relocate a fledgling because of a cat. Relocate the cat. Keep children, dogs and cats away.
Do not use wire cages to transport a bird.
If a bird’s nest has been built in an unsuitable location (example: a boat parked in the driveway and not used much) then move the nest 10 inches a day until you relocate to a better place.

Many times people think that a nest has been abandoned and call for help. The parents may be away from the nest gathering food and you may not see them rush in and rush out to feed. Don’t be alarmed if you haven’t seen the parents in a while. If you have concerns then sit in a car or watch from a window for an hour. Do not look away.
It is not uncommon to find a nest on the ground after a storm. Securely replace the nest to the location it came from or as close as possible...keeping it out of direct sun and not exposed to predators. Replace the babies and quietly back away so the will not jump out. It is not true that birds will abandon their young after humans have handled them. Watch for a couple of hours and see if the parents come to feed. If not then bring the babies inside and keep in a warm place until you are able to reach a rehabber.
If a baby has fallen from the nest and you can see the nest but it is too high to reach, then you may try creating a nest using a small woven basket or berry basket lined with shredded paper towels. Attach it securely to a location close to the original nest. Watch to see if the mom and dad will continue to feed and care for the baby. Place this makeshift nest out of direct sunlight. It would be great to have the nest protected from rain as well.

If you have found an injured adult bird place him in a well ventilated box or pet carrier (not wire cages) with paper towels or an unfrayed towel on the bottom. Keep the bird in a warm isolated part of your house away from children or pets. Only check in on the bird when necessary. The bird will freak out every time you peek in on him which could do more harm to his injuries. If you are unable to reach a rehabber right away you may provide seed and soaked dry dog or cat food. Provide a small container of water…making sure the container is heavy enough not to turn over.
Birds that have run into windows will many times recover. Place the bird in a paper bag or in a box with air holes. Place in a QUIET place for an hour. Each time you check on the bird, bring him back outside. Open the bag or box and if the bird doesn’t take off then try again in another hour. Try for 3 hours. If the bird has one wing down (dragging) or a bad head tilt then the caller will need to get the bird to a vet or rehabber.
During the summer months (usually around July), you may hear chattering in your chimney. This is usually from a nest of Chimney Swifts. Please do not build a fire and smoke them out. They cannot leave until they are able to fly. PLUS there is a fine of $15,000.00 or six months in jail for failing to follow regulations in dealing with removal. Consider yourself lucky to have these beautiful delicate birds that can eat up to 2,000 insects a day. If one of the babies should fall down into the fireplace then you can try reaching up into the chimney, above he damper, and the baby will grip the side and crawl back up. Close the damper once the baby has crawled up. If he is too weak to climb then call a rehabber. Once the babies have left the nest (several weeks) and you don’t want them to return next year, then you must have your chimney capped.
An injured adult will need an experience rehabber. Please call and get advice.
If you should find a baby owl or hawk then try reaching a rehabber before removing it from the area.
