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.

Red-crested Cardinal

A striking medium-sized bird with brilliant red crest, white face, and grey body native to South America from Bolivia and Brazil to Argentina, red-crested cardinals have been introduced to Hawaii and other Pacific islands, becoming iconic garden birds in Honolulu. They inhabit dense shrubs, grassland edges, and suburban gardens, foraging on seeds and small insects. Despite their name and superficial resemblance, they are not closely related to North American cardinals but belong to the tanager family.
