They only appear to be orphaned or abandoned. Chances are, a parent is nearby watching you and waiting to care for the young. Do not touch or handle young wildlife. Remember to watch for wildlife all around you, not just on the ground. Follow signs and obey posted rules.
Rules prohibiting removing, touching and feeding wildlife are extremely important.
When humans feed animals, the animals' chances for survival may be jeopardized. Animals fed by humans tend to lose their sense of place in the natural world and may grow dependent on handouts or become hostile toward humans. In addition, pets are best left at home or in your vehicle while you're watching wildlife. Dogs or other pets may chase or injure wildlife, so keep your pets secure and away from restricted areas. Be courteous to others.
