You can t learn everything about all species, so focus on a group that interests you and become as proficient as you can with it. For example learn to identify birds in all their plumage phases and by their songs. Learn about our mammals, their life histories, tracks, what habitats they use and how abundant they are. A lot of time spent in the field, with reference material and with people who have a similar interest will get you the experience you need. Join a naturalist club or a wildlife association or visit museums and talk with the people there about your interests.
Formal education is important too.
Completing High School is compulsory. For those wishing to further their education there are many Universities and technical schools in Canada offering training in fish and wildlife. No matter what schools you attend it is important to bring your experience and formal education together to develop your own interests. But don t feel that you must have a full-time job in the wildlife field to be important. Nova Scotia has a rich history of amateur naturalists who have made great contributions to the knowledge of fish and wildlife here and around the world.
