Auguste Boissonneau
Auguste Boissonneau (26 July 1802, Saumur – 7 July 1883, Paris) was a French ornithologist and ocularist. In the latter field he was a pioneer of ocular prosthesis.
As an ornithologist, he was the taxonomic authority of numerous species native to tropical and subtropical South America. The hummingbird genus "Boissonneaua" commemorates his name, as does the species "Pseudocolaptes boissonneautii" (streaked tuftedcheek), a bird circumscribed by Frédéric de Lafresnaye in 1840.

The genus "Oxypogon" was first described by French ornithologist Auguste Boissonneau in 1840.

The other member of the genus "Chalcostigma" lay outside the group, suggesting the genus might need revising in the future.
The most common species, the white-bearded helmetcrest, measures in length, it is a small hummingbird
