This passenger pigeon egg is from the collection of James Bond, the real ornithologist and inspiration for the fictional spy. Bond worked at the Academy of Natural Sciences in Philadelphia and specialized in Caribbean birds. According to the label, the egg was collected in 1849 (not by Bond, who was born in 1900). It was later obtained by Jacques Perrin de Brichambaut and is now in the collection of the Muséum de Toulouse (Muséum d’Histoire Naturelle de la ville de Toulouse) in France.
