Currently there are no non-mammalian amniote ontologies but in future this may import a chick ontology. Uberon ontologies with the prefix 'collected' are ontologies that import the core Uberon ontology together with one or more external typically species-centric ontologies plus *bridging* axioms that connect Uberon to the species-centric ontology. Bridging axioms may be direct equivalence axioms, taxonomic equivalence axioms, or subclass axioms. See the Uberon homepage for details.
