Bald eagles are an iconic species of bird native to North America, particularly prevalent in regions surrounding water bodies such as rivers, lakes and oceans due to their preference for fishing as a primary food source. Renowned for their distinctive white heads and tails contrasting with dark brown bodies, they embody a powerful presence with wingspans reaching up to 7.5 feet. Adults can weigh between 3-6.5 kilograms while juveniles are slightly smaller. They have excellent vision that allows them to spot prey from great heights and sharp talons for capturing and carrying fish. Nests, referred to as 'aeries', are built high in trees or on cliff edges using branches and twigs, often reused and added upon year after year. Known for their monogamous nature, bald eagle pairs typically mate for life, engaging in elaborate courtship rituals involving calls, swoops and cartwheels in the sky. Their population decline during the 20th century due to habitat loss, pesticide exposure and hunting led to them being listed as endangered; however, protective measures have resulted in successful recovery, leading to their removal from the Endangered Species List in 2007.
