In addition, the ornithological collections are particularly rich, with eggs, nests and taxidermy of all of the birds of Maine-et-Loire. There are also specimens belonging to extinct species, including a Carolina parakeet and a passenger pigeon; casts of an "Aepyornis" egg and of a moa's leg bones can be seen. There are also historical specimens, including one of the last sturgeons fished out in the Loire in 1811, and cetacean bones of the same period. Among the last remarkable acquisitions, the arrival of an okapi (accompanied by its skeleton) is noteworthy.
