Unlike human babies, wild babies are not constantly watched by their parents and spend large amounts of time alone. In many cases, wild babies should be left alone.
In the event you do find a baby bird or mammal, unless you know that the parents have been killed or it is obvious that the baby is injured, observe the animal and the area from a distance to make absolutely sure the parents are not around before you intervene. Once the baby is removed from the area and transported to a local veterinarian, animal control or a rehabilitator, the resources available to us to return that baby, if he is healthy are limited.
It is our goal to keep the healthy babies with their parents which allows us to utilize our resources for the babies who really need our help.
