Hart admits that she has good help, but without a money tree, she has space and people shortages. In some cases, there is just no room at the inn. Even though her employees are not required to take in the animals, they often do take on the task of getting the needy critters to other volunteers or rehabilitators in the area. In some cases, educating the rescuer is all that is warranted. Their parents are most definitely the best caregivers.
Mammal babies are harder to put back for their parents to return to, but sometimes that even works.
Baby squirrels, if not cold or covered in ants can be put into a pillowcase and nailed high in a tree close to where they fell. Usually the parents will retrieve them. Most of the time nature knows what it is doing says Hart. But if some intervention is needed, rehabilitators are the best resource. And if they can't help, they will direct those with injured or abandoned babies to someone who can.
