. The Canadian field-naturalist. 1996 Cranmer-Byng: A Life with Birds 83 tion? The first and chief result was that Tavemer, as the ornithological specialist at the National Museum of Canada, had been able to form an opinion, based on research, of the cormorant question: His first impressions were given in a letter to his mother and sister as follows: "The Cormorant question is interesting. I always thought the damage they do was exaggerated but not to the extent that the evidence shows. Their effect on the salmon is almost nil. Those in tide and salt water feed almost entirely on sculpin and eels. Those in fresh must eat salmon, but one of their bitterest enemies only admits of seeing 3 or 4 Cormorants up river in a year, so you can see what that means. However I will have an interesting report to write as it touches several phases of the subject that I have always wanted to write about.'"^^ His nature observations were set down in a study 'â printed in the museum Bulletin in April 1915 entitled "The Double-crested Cormorant {Phalacrocorax cutritus) and its Relation to the Salmon Industries on the Gulf of St. Lawrence".36 This dealt with the bird's food habits at length. His conclusion, based on data examined, was that they fed almost entirely on species other than salmon, but that they inconve- nienced fishermen locally by taking some of the her- rings out of their nets. Taverner also took this oppor- tunity to start a study of a colony of breeding Northern Gannets including a collection of his own photographs. This study was to continue the follow- ing summer and was eventually published in The Ottawa Naturalist in May 1918 at a time when the whole future of Bonaventure Island was uncertain. This article represented his mature thoughts on the birds of Bonaventure Island, especially the Gannets. Finally the expedition was a valuable learning expe- rience for Tavemer that did much to increase his self confidence. He matured as a consequence. He
