Nature covers so many different areas. It could never be boring - always something new to learn. Investigate birds, mammals, reptiles, arthropods, fish, plants, rocks, and how they all fit in the scheme of things.
Scouts must bring a blue merit badge card signed by their unit leader. Leader supervision is necessary for each event. Absolutely no walk-ins.
Read the Nature Merit Badge Handbook. Do requirement #4a 2 (bird feeder observation) and bring the notebook with you to class.
