I recently stumbled upon two more passenger pigeon mounts I was unaware of. The Horninam Museum and Gardens in London, England, has two mounted passenger pigeons, a male and a female. Photos of the birds (NH.Z. 1768 and 1769) can be seen at the museum website.
The two pigeons are part of a natural history collection amassed by Samuel Prout Newcombe in the nineteenth century. Newcombe had owned a number of photography studios in London in the mid 1800s. He also was a writer, and in 1851 wrote a guide to the The Great Exhibition (also known as the Crystal Palace Exhibition) that focused on foods of the world, including an entry on the passenger pigeon. Around 1870, Newcombe sold his photography studios and retired to life a leisure.
Keenly interested in natural history, Samuel Prout Newcombe had amassed a large collection of specimens and books on natural history. … “Nature“, the International Journal of Science, reported in 1899 that: “Mr. S. Prout Newcombe has offered the London County Council his educational collection of natural history specimens and literature. This collection, which consists of about 21,000 objects, included a considerable number of works on natural history subjects“.

The Horniman received the Newcombe collection in 1905.
