Medium Ground-Finch Skull Replica (Geospiza fortis) Information
Medium ground-finch skull replica measures 1.05 x 0.65 x 0.70 inches. Geospiza fortis skull is museum-quality polyurethane resin cast from California Academy of Sciences specimen. 2-part skull (separate cranium and mandible) 1:1. Adult male. Made in USA.
Anatomy of the Medium Ground-Finch
The Medium ground-finch is a cornerstone of evolutionary study in the Galápagos. The California Academy of Sciences maintains specimens that showcase the rapid cranial adaptations required for a generalist diet. Below are the unique features of this highly variable ground finch.
Robust Crushing Morphology
In mature males such as the CAS specimen, the bill is stout and conical, providing a powerful tool for crushing seeds. Furthermore, the structural depth of the beak at the base allows the bird to exert significant pressure. Unlike the more specialized tree finches, this adaptation is optimized for ground-based foraging.
The Seed-Cracking Generalist
The skull features a reinforced mandible designed to crack hard seeds. This allows the bird to access high-energy nutrients even when soft food is scarce. While it is primarily a seed specialist, its robust beak consequently enables it to exploit larger, tougher food sources during severe drought cycles.

Explore the intermediate beak morphology of this Galápagos finch with a 1:1 scale museum-quality cast of an original CAS specimen. This replica highlights the distinct culmen curvature and crushing depth essential for Darwin’s finch osteology studies. It serves as a vital comparative tool alongside our green warbler-finch skull, small tree-finch replica, and woodpecker finch cast. For a comprehensive evolutionary study, we also offer the complete set of 12 Darwin’s finches in our avian collection. This geospiza fortis model provides the precise anatomical detail required by professional biologists. Shop for more museum-quality replicas in our bird or aves replica store.
