Two birds that were victims of overhunting are passenger pigeons and great auks (a type of bird). Both were hunted to extinction.

What are some examples of overharvesting?

Overharvesting is alive and well. For example, unsustainable fishing practices, such as bottom trawling and blast fishing, are still practiced today, and we’ve seen significant declines in several commercial fish populations, such as Atlantic halibut, to the point where their survival is threatened.
