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.

Yellow-bellied Seedeater

A small, distinctive seedeater with yellow underparts and a conspicuous black bib in males, yellow-bellied seedeaters inhabit weedy fields, forest edges, and grasslands from Costa Rica through South America to Argentina. Males have black upper parts with chestnut flanks contrasting with yellow belly. They form large flocks on grass seeds and agricultural weeds. Popular as cage birds in South America for the males' attractive plumage and melodious song. Listed as Least Concern with widespread and stable populations.
