In this section, examples of Gould's works are presented in chronological order, showing how the drawing techniques developed as Gould matured. The artists employed in the illustrations differ in each period, and because of developments in the lithographic and colouring processes, at first glance the later works seem to be the more beautiful. However, it can be said that Gould's illustrations for each of his works represent the highest standards of such works in the time of their respective publication dates. It is because each illustration is a realisation of Gould's vision of Nature that these plates continue to fascinate, more than 100 years after their publication.

It would be biased to emphasise only the beauty of his illustrations when assessing Gould's achievements, since he also published many written works, as well as a large number of scholarly treatises. His books were the accumulation of such treatises, and there are many birds which have entered the public knowledge through his works. Gould's greatness lies in his scholarly achievements as well as his illustrations.
