An Arctic biologist, Dr. David Gray has studied mammals and birds in Canada’s Arctic since 1968. Currently a Research Associate with the Canadian Museum of Nature, he has made over 30 research trips to the Arctic islands, studying the behaviour of several of the region’s birds and mammals. David has also written two books about the Arctic and has worked on a number of Arctic films and museum exhibits.
What is an Arctic biologist? A biologist studies the life of plants and animals and how they relate to their environment. Studying the behaviour of Arctic birds and mammals reveals the details of how certain species survive in the harsh environment, and how changes in their behaviour may be related to changes in the Arctic environment.
For Expedition Arctic, David set off on a mission to study and explore the Arctic’s exciting and awe-inspiring wildlife. As the Arctic climate changes, David is interested in how changes in a species’ behaviour may be related to changes to its habitat.
