The below chart is a quick guide for intervention with baby birds.
Remember, in many cases, its best to leave the birds alone. Parents may be off the nest for hours at a time, baby birds may leave the nest before they are ready to fly, and in most cases, this is just a normal part of nature. However, if you suspect danger or injury to the birds, it's best to involve a licensed wildlife rehabilitator.
