Common name: Blue-headed Sapphire. From A monograph of the Trochilida, or Humming Birds, 1849-1877.
John Gould was an English ornithologist. The Gould League in Australia was named after him. His identification of the Galapagos birds (now nicknamed "Darwin's finches") as being all finches was pivotal in the advent of Darwin's theory of evolution by natural selection.
Throughout his professional life Gould had a strong interest in hummingbirds. He accumulated a collection of 320 species, which he exhibited at the Great Exhibition of 1851. Gould published many works on birds and mammals, one of which was A Monograph of the Trochilidae or Humming Birds with 360 beautiful plates, among them a number of the plates in our collection.
