To determine whether a comma or semicolon is needed in the given sentence, we need to understand the main components and their relationship to each other.

The sentence contains two main clauses: "conservation efforts to save the endangered whooping crane were instituted" and "more than four hundred of the birds are alive today." These clauses are connected by the coordinating conjunction "thus."

A comma is typically used before a coordinating conjunction when it connects two independent clauses, as is the case here. Therefore, we need a comma before "thus" to separate the clauses.

The corrected sentence would be: "In the late 1960s, conservation efforts to save the endangered whooping crane were instituted, thus more than four hundred of the birds are alive today."
