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.

Rainbow-bearded Thornbill

One of the most colorfully named hummingbirds, rainbow-bearded thornbills display a distinctive long, multi-colored gorget — glittering from green to blue to violet — in a uniquely elongated beard-like pattern. They inhabit open páramo grassland and scrub at very high Andean elevations from 3,200–4,500 meters in Colombia, Venezuela, Ecuador, and Peru. Among the highest-altitude hummingbirds, they forage on low-growing páramo flowers and are adapted to sub-zero night temperatures through nocturnal torpor.
