Which five animals require PGC approval to kill trap?

The answer identifies five specific animals that require Pennsylvania Game Commission (PGC) approval for killing or trapping. This requirement is in place primarily to protect certain species that are regulated due to their ecological importance, population levels, or conservation status.

In Pennsylvania, beavers and black bears are examples of game species that require special permits due to their management and conservation regulations. Woodpeckers and blackbirds are also included, as they are protected under both state and federal laws concerning wildlife. The inclusion of these species indicates the necessity for obtaining proper authorization before taking any lethal action against them.

The other provided options contain species that either fall under less strict regulations or do not require PGC approval for trapping or killing under certain conditions. For instance, species like raccoons and squirrels are often perceived as nuisance animals that can be managed more freely under current regulations. Thus, the distinction in management guidelines ultimately clarifies why option A is the focus, highlighting the need for permits with regard to those specific animals listed.
