Black-and-white Seedeater

A small, boldly patterned seedeater with striking black-and-white plumage in males — jet black upper parts and wings contrasting with white underparts — black-and-white seedeaters inhabit open and semi-open habitats including grassland, forest edge, and plantation shade in the Andes from Colombia to Bolivia. One of the more distinctively patterned Sporophila seedeaters. Females are plain brown and buff. They forage on grass seeds and are sometimes kept as cage birds for the males' patterning and song.

common bottlenose dolphin

The most studied and recognized dolphin species, bottlenose dolphins inhabit warm and temperate oceans worldwide, from coastal shallows to the open sea. Highly intelligent with large brains relative to body size, they demonstrate self-recognition, complex communication, and social learning. They live in fluid fission-fusion societies and cooperate to herd fish. A keystone indicator species for marine ecosystem health.
