Eucephala caerulea (Blue-chinned Sapphire)

The image was produced using lithography, a printmaking technique, and was then hand-colored to achieve vivid representations of the birds and plants. The level of detail in the illustration highlights the artist's skill and attention to naturalistic accuracy.

The print is from Gould's extensive ornithological studies, which were often collaborative efforts with illustrators like his wife Elizabeth Gould and artists such as Edward Lear. His work, including the seven-volume 'The Birds of Australia', was influential in the field and later contributed to Charles Darwin's research.
