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.

Ruddy-breasted Seedeater

A tiny, chestnut-red seedeater of open grasslands, weedy fields, and marshes distributed across Central America and most of South America east of the Andes to Argentina, ruddy-breasted seedeaters have warm rufous-red plumage in males with darker wings. Among the most widely distributed Sporophila seedeaters, they thrive in disturbed agricultural landscapes and secondary growth. They forage in small to large flocks on grass seeds and cereal crops. Least Concern with populations benefiting from agricultural expansion.
