gray wolf

The most widely distributed wild canid, gray wolves range from North America across Eurasia in diverse habitats including tundra, forests, and grasslands. Highly social animals living in family packs led by a dominant breeding pair. As keystone predators, wolves regulate prey populations and profoundly shape ecosystem structure, as demonstrated by their reintroduction in Yellowstone. Once heavily persecuted, populations are recovering in many regions.

Green Hermit

A large hermit hummingbird of humid rainforest in Central America and the northern Andes, green hermits are named for the males' predominantly green plumage — unusual among hermits which are generally brown and buff. Females have blue-green upper parts and rufous underparts. Found from Costa Rica to Peru and Venezuela at elevations up to 1,600 meters in forest understory. They are important pollinators of large Heliconia and Calathea flowers along the forest floor, following established trap-line routes.
