Naturalists are curious, observant, and passionate about the world around them, with a particular fascination for nature. Naturalists often document what they see, enjoy sharing their knowledge, and are motivated to continually expand their knowledge.
And he also stated that:
Many naturalists have no formal training in biology, and don’t have advanced degrees. They may have binoculars, probably have paper and pen, and they have an ability to observe carefully and critically and feel joy and appreciation about what they are observing. They are the elderly, they are children. My eldest son (when he was about 5 years old) collected, pinned and labelled some insects from our neighbourhood, and I consider that to be an activity of a naturalist.
