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.

White-sided Flowerpiercer

A medium-sized flowerpiercer of humid Andean cloud forest and forest edges from Colombia south to Bolivia, white-sided flowerpiercers have distinctive white flank patches contrasting with dark grey-blue plumage. Like all flowerpiercers, they use their sharply hooked and slightly upturned bill to pierce the base of tubular flowers and steal nectar without pollinating — earning them the reputation as nectar thieves. Found at elevations of 1,500–3,500 meters, they are commonly encountered in Andean gardens and forest edges.
