He became a FRSC in 1934 and won the Favelle Medal in 1946. He also studied the cyclical population fluctuations of birds and mammals through banding studies, and became a strong proponent of wildlife conservation. He was a noted artist whose works were exhibited in Canada and England. His drawing of a crane was chosen for a postage stamp.
