Blue-tailed Emerald

A small, jewel-like hummingbird named for the brilliant blue-green iridescence of the tail feathers, male blue-tailed emeralds display glittering green plumage throughout with a contrasting deep blue-green forked tail. Found in lowland tropical forest edges, savannas, and gardens from Venezuela and Colombia east to Trinidad and south to Bolivia and Brazil. They are common in disturbed and secondary habitats, making them relatively resilient to habitat modification compared to more specialized hummingbirds.

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.
