In recent years, black vultures have been expanding their range northward. Common in the southeastern U.S., black vultures now range at least as far north as Pennsylvania and southern New England. 

The reintroduction of apex predator species to parts of their historical range continues to be a hot-button topic in the western U.S. Concerns and discussions have arisen in regard to federal plans to establish a grizzly bear population in the North Cascade Range of Washington state.

Despite growing questions about where the animals will be sourced from, Colorado wildlife officials are continuing with a plan to reintroduce a gray wolf population to the state by the end of 2023.
