Helping Out a Healthy Bird.
If you don’t see any injuries on the bird, but are worried that it has been abandoned follow these steps based on how mature the bird is.
Nestlings: If you find a nestling away from the nest, the best thing you can do is try to return it to its nest. That thing about mama birds abandoning their young because they have the scent of humans on them? Totally untrue. If you can’t find or reach the nest — sometimes they are very well hidden — place the bird in a strawberry box (or any type of small box) that has been lined with tissue. Suspend the box from a branch close to where you think the nest is. Next, and this is very important, leave the area. The bird’s parents are very wary of disturbances, and it might take hours for them to come back and retrieve their young. The longer you linger, the longer this will take.
Fledglings: If you find a fledgling on its own, it is usually best to not do anything at all. The bird may seem helpless and abandoned, but that is almost never the case (unless, of course, the fledgling has been injured). The most you should do is try to keep people and other animals away from the fledgling — placing it back in its nest won’t be much help.
The Bottom Line: The vast majority of baby birds don’t need your help. Removing a healthy, growing bird from the wild is far more dangerous than letting it stay outside — the baby may not be able to learn the vital skills it needs to survive. When in doubt, contact your local wildlife rehabilitation center.
