Mr. James Barclay, and Mr. Smith of Uyea Sound, both say that the wild rock-pigeon can be easily tamed; and the former gentleman asserts that the tamed birds breed four times a year. Dr. Lawrence Edmondstone informs me that a wild rock-pigeon came and settled in his dovecot in Balta Sound in the Shetland Islands, and bred with his pigeons; he has also given me other instances of the wild rock-pigeon having been taken young and breeding in captivity.

[17] Domestic pigeons of the common kind are mentioned as being pretty numerous in John Barbut’s ‘Description of the Coast of Guinea’ (p. 215), published in 1746; they are said, in accordance with the name which they bear, to have been imported.
