Owlets, like this Eastern Screech, will leave the nest before they can fly. That doesn't make them an orphan!

The best thing you can do to help them is to make sure your pets are inside. You can watch from afar, preferably with binoculars, to insure the presense of a parent or two. They won't come near if you are too close!

Incidentally, the same applies for a fawn. Its mother will leave it alone in a hidden location. The fawn's spots resemble dappled sunlight falling through the leaves and so it helps to camouflage the animals tiny body. The doe will return to nurse her offspring and then will lick it completely free of scent. The fawn is kept safer this way, as it is unable to flee from danger with the speed and agility it will attain as it ages. Many people happen across these fawns and in meaning well, will actually fawn-nap them from their mothers. If you don't see a deceased parent, you probably aren't seeing an orphan. As with the owlets, if you stand a close watch, the parent will not return.
