Twenty years ago when I was writing The Red Canary—the story of how in the 1920s a bird enthusiast and a biology teacher created a red canary—I needed to include an overview of the history of canary domestication. To obtain the necessary information, I started to collect eighteenth- and nineteenth-century books on canary breeding. As this was before many of these books became available on-line, I regularly checked for editions available at local and international booksellers.
Charles Darwin’s book The Variation in Animals and Plants under Domestication, from 1868, provided an overview of variation, selective breeding and the process of domestication. In it, he covered the domestication of dogs, cats, pigeons, chickens, and (briefly) the canary. As his main source of information on the canary, Darwin cited a book by Bernard Brent . Brent was a shipbuilder who was also a pigeon, poultry and cage bird enthusiast. He lived not far from Darwin and was a regular contributor to the Cottage Gardener  to which Darwin subscribed.
I eventually obtained a wide range of books on canaries, but Brent’s book, The Canary, British Finches, and some other Birds, eluded me. Despite regular inspection of the on-line second bookshops over several years, I never once saw Brent’s book offered for sale. Although this was slightly frustrating, it was not a major obstacle for my research since, I was able to use the copy once owned by Darwin himself, in the Cambridge University Library.
The apparent scarcity of Brent’s book made me suspect that only a few copies had been printed, but it also made me wonder whether Brent might not have been highly rated by the cage-bird cognoscenti. This view was reinforced, when I discovered that Brent had made a mistake—and one that Darwin repeated in Variation —when he claimed that there existed a feather-footed breed of canaries. Brent had obtained this information from a mistranslation of the word ‘duvet’ (meaning down feathers) as ‘rough-footed’ (for unknown reasons) in the English edition of a well-known book about canaries by the French author J-C. Hervieux . In his book, Brent wrote: “The rough-footed or feather-legged Canaries now seem to be very scarce, if the breed is not altogether lost, as I do not remember having seen but one, and that many years back.”  This suggests that he thought he may have seen one, which, of course, he could not have done as they do not exist.
My scouring of the on-line second-hand bookshops identified some twenty other books on canaries that Darwin could have cited in Variation, so why did he use Brent? The main reason I think was that Brent was one of first to enumerate and illustrate the different canary breeds. The drawings aren’t great (see illustration to the left ), but as they say, a picture is worth a thousand words. A further five or ten years were to pass before images of the different breeds in colour became available (see below).
Darwin knew Brent personally. They first met after Darwin became interested in the artificial selection of pigeons in 1855 and attended a fanciers’ meeting in London . After this initial encounter Darwin wrote to his son William referring to Brent as “a very queer [meaning unusual] little fish”, adding that “all pigeon fanciers are little men, I begin to think” . Brent was indeed small in stature  and, according to Darwin. both “a very obliging kind man, but very crotchetty”  and “eccentric” . Nevertheless, Brent and Darwin corresponded and Brent visited Darwin’s home  and became Darwin’s chief source of poultry information , as well providing other details such as the breeding canary-finch hybrids . It is also possible that Brent gave Darwin the copy of his Canary book.
Last week, some fifteen years after The Red Canary was published, I was looking for another old bird book on-line. Failing to find it reminded me of my earlier quest for Brent’s book. I looked again, and to my amazement, there was copy in a bookshop on England’s south coast. I couldn’t resist it—hence the inspiration for this essay.
