Bald Eagle
Least ConcernThe bald eagle is a majestic bird of prey and the national bird of the United States. Easily recognized by its snowy-white head and tail, dark brown body, and bright yellow beak and feet, it is a powerful flyer.

They build the largest nests of any North American bird, which can reach up to 4 meters deep and 2.5 meters wide.
Birds (Aves)
Emperor Penguin
Near ThreatenedThe emperor penguin is the tallest and heaviest of all living penguin species. Living in the harshest winter environment on Earth, they breed during the Antarctic winter on sea ice. Females lay a single egg and immediately return to the ocean to feed, leaving the males to incubate the egg. Males balance the egg on their feet under a warm brood pouch for about 64 days, fasting through extreme winds and temperatures as low as -60°C.
Birds (Aves)
Peregrine Falcon
Least ConcernThe Peregrine Falcon is a widely distributed bird of prey renowned for its incredible flying speed. It holds the title of the fastest animal on Earth, reaching speeds exceeding 320 km/h (200 mph) during its signature hunting dive, known as the 'stoop'. Peregrines are highly skilled aerial hunters that specialize in capturing medium-sized birds mid-air. Once severely endangered by pesticide usage, populations have recovered successfully under conservation laws.
