[6] In 1927 de Kiriline Lawrence emigrated to Canada and continued to work as a nurse, joining the outpost service of the Canadian Red Cross Society.
Percy A. Taverner encouraged her to band birds; Doris Huestis Speirs and Margaret Morse Nice also served as mentors to de Kiriline Lawrence.
[6] From 1948, she conducted a 15-year correspondence with Alexander Skutch, with whom she shared interests in natural history, field observation, and writing accessible to the general public.
[8] She is recognized for her study of the red-eyed vireo, which identified the songbird as capable of producing 22,197 distinct calls in a single day.
[9][10] She published nearly twenty scientific papers in The Auk, The Wilson Bulletin, and The Canadian Field-Naturalist and more than 40 articles for Audubon and other popular magazines.
[6] De Kiriline Lawrence carried out the majority of her scientific work on her property, located outside of North Bay, Ontario.
Working from the most northerly bird banding station in Ontario, de Kiriline Lawrence made significant contributions to the knowledge of the northern limits of many North American species, chief among them red crossbill, Loxia curvirostra.
