Note 27 — Chapter V · DOMESTIC PIGEONS.
Reading edition
‘Coup-d’œil sur L’Ordre des Pigeons,’ par C. L. Bonaparte (‘Comptes Rendus’), 1854-55. Mr. Blyth, in ‘Annals of Nat. Hist.,’ vol. xix., 1847, p. 41, mentions, as a very singular fact, “that of the two species of Ectopistes, which are nearly allied to each other, one should have fourteen tail-feathers, while the other, the passenger pigeon of North America, should possess but the usual number—twelve.”
