Naturalist Legal & Safety Notice
Bird Feathers: Under the Migratory Bird Treaty Act (MBTA) and CITES, possessing feathers of native wild birds (even found on the ground) is strictly prohibited without scientific permits.
Scat Hygiene: Never touch animal droppings with bare hands; carnivore scat may harbor zoonotic parasites (e.g. Echinococcus or Toxoplasma).
