Common Seal

The most widely distributed pinniped, harbor seals inhabit temperate and subarctic coastal waters of both the North Atlantic and North Pacific. Adults reach up to 130 kg and spend roughly equal time at sea hunting fish, squid, and crustaceans and hauling out on beaches or rocks to rest. Their large, expressive eyes are adapted for underwater vision in low light. Harbor seals are a critical food source for orcas, sharks, and polar bears.

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.
