Explanation:

The two independent clauses "Storks live mainly in Asia, Africa, and Europe" and "however, one species, the black - necked stork, also lives in Australia" are connected. When using a conjunctive adverb like "however" to join two independent clauses, a semicolon should be used before the conjunctive adverb.

Storks live mainly in Asia, Africa, and Europe; however, one species, the black - necked stork, also lives in Australia.
