Puzzle: Ernst Haeckel Hummingbirds

When German biologist Ernst Haeckel published Art Forms in Nature, it encapsulated his response to Charles Darwin's On the Origin of Species. But Haeckel also clearly saw his illustrations as more than just scientific documentation. His elaborate forms have been called a precursor to Art Nouveau, and his influence even stretched to architecture.

This 300-piece puzzle features Trochillidae - Kolibris, from Kunstformen der Natur (Leipzig and Vienna: Bibliographisches Institut, 1904), plate 99.
