Fully feathered baby birds. Place them in a nearby tree or bush. The parents will generally feed them occasionally until they are getting along well on their own. Healthy babies that have been touched by humans. It is a myth that the parent will no longer care for them.
All wild animals are risky to handle.
If the animal bites you, it may have to be euthanized and checked for rabies. Ffor its sake as well as your own, call for help if you are unsure whether you can capture it safely without assistance. Adult mammals that are mobile will require special equipment in order to catch them, even if they are injured. Do not attempt to catch them yourself. Leather gloves can protect you from nips and scratches.
