Percy Algernon Taverner, Canadian Ornithologist

Percy’s Biography can be found at (

P.A. Taverner was born Percy Algernon Fowler in Guelph, Ontario in 1875. After his parents separated and his mother remarried, he took on his mother’s second husband’s surname. Taverner, a self-taught naturalist, was the first ornithologist at the National Museum of Canada, now the Canadian Museum of Nature, from 1912 to 1942. He also helped to establish the Point Pelee National Park and a number of bird sanctuaries across Canada, including Bonaventure Island.

He is the original designer and engineer of the now called Taverner Purple Martin House which has been modified in both wood and aluminum to suit today’s housing standards. Have a look at his bio., his original plans and some of the articles and books which he authored. He was well ahead of his time in both his martin observations and suggestions.

In 1919, he wrote an article called “Bird-houses and Their Occupants”, that was printed in the early 1919 edition of a publication called The Ottawa Naturalist.

The original blueprints of his Martin house design:

Taverner’s first attempt at a Purple Martin House (Photo below) required that the house could only be accessed with a ladder or taken down at the end of the season. Nevertheless, the martins in numerous numbers occupied this house in Ottawa, Ontario.

P. A. Taverner’s second attempt at building a purple martin house for his garden turned out just as his plans were designed. Since he was a fine architect as well as an ornithologist, he seemed to know what was best for the purple martin. His thinking about the design was ahead of its time: a house that can be lowered; a house that could trap invasive species; a house that could be monitored. He was truly a Purple Martin house builder ahead of his time over 100 years ago.
