Eagles Found In Texas
How many species of eagle are there?
Eagles are birds of prey in the family Accipitridae; there are approximately 60 different species. The majority are found in Eurasia and Africa, with only 14 species found in other areas including North, Central and South America, and Australia.
What do eagles look like?
With the exception of some vultures, eagles are generally larger than other birds of prey. They have strong muscular legs, powerful talons and large hooked beaks that enable them to rip the flesh from their prey.
Eagles vary in size. One of the smallest species, the little eagle, is around 17.7–21.7 in (45–55 cm). In contrast, Stellers’s sea eagle is around 36–42 in (91–106 cm) in size, and wingspan can reach approximately 72–96 in (2–2.5 m).
What do eagles see?
Sight is the strongest of all eagle senses. The eyes are large, can take up almost 50% of the head, and can weigh the same amount as a human eye. An eagles vision is 4–5 times better than that of a human. Eagle eyes are angled 30 degrees away from centre of the face, which gives eagles a greater field of view. Eagles can see five basic colours to our three, and can detect UV light.
Cones are light detecting cells that are sensitive to colour. One of the reasons that eagles have better vision than humans is because their retinas, a layer at the back of the eyeball, have more cones. We have 200,000 cones per square millimetre, whereas eagles have one million.
Do eagles mate for life?
Eagles are monogamous, so generally mate for life. They have strong site fidelity, so a mating pair tend to reuse the same nest year after year. Nests, composed of sticks, vegetation, and downy feathers, are built by both males and females.
Location of the nest varies with species. Bald eagles for example, most likely nest in tall trees whereas as golden eagles prefer cliff faces or more open areas.
How many eggs do eagles lay?
The number of eggs laid will depend upon species, but many eagles lay between one and three eggs; four egg clutches do occur, but they are rare.
What do eagles eat?
Eagles are apex predators, meaning they are at the top of the food chain. What eagles eat depends upon the species and the food that is available to them, but they are all carnivorous and live on a diet of meat and/or fish.
Eagles can be divided broadly into four groups; sea eagles, booted eagles, snake eagles and giant forest eagles. Booted eagles have a relatively wide diet consisting of birds, small mammals, reptiles, rodents, amphibians and insects, whereas others are more restricted. Sea eagles or fish eagles feed mostly on a diet of fish whilst snake eagles specialise on capturing reptiles. Giant forest eagles feed on various forest animals. One of the largest eagles, the Harpy eagle, feeds on larger animals including monkeys, sloths and coatis.

With acute eyesight and swift flying ability, the Bald Eagle (Haliaeetus leucocephalus) is a magnificent bird of prey unique to North America.

Bald Eagle Information
Adult bald eagles, both male and female, have a distinctive white head and tail, and a body and wings of a dark brown color. Their beak and feet are bright yellow. The average size of a full grown eagle is 30 to 32 inches tall, and has a wingspan measuring six to seven feet. Male bald eagles weigh between 7 and 10 pounds, with females being considerably larger, and weighing up to 14 pounds. Young eagles, or “eaglets,” have plumage that is brown and speckled with white, and have a dark brownish-black beak. The eagle will not develop a distinguished white head and tail until they are 4 to 5 years old.

Bald Eagles are a monogamous bird, which means they stay with the same mate their entire life. If either bird happens to die, the eagle will find a new mate. Every mating season, which occurs anywhere from late September to early April (depending on the region), the female eagle will lay one to three eggs. She lays the eggs about five to ten days after mating. Both sexes take turns incubating the eggs for 32 to 35 days until they hatch. After the eaglets have hatched, the young will remain in the nest for 10 to 12 weeks while both parents share the responsibility of feeding them. After they have learned to fly and hunt, the eaglets leave the nest. However, disease, starvation, bad weather, and predation cause more than 50% of eagles to perish during their first year. If the eagle survives, it can live about 20 to 30 years in the wild.
Bald eagles have tremendous eyesight with a visual acuity six times better than that of humans. They are capable of seeing over 1-1/2 miles away. This exceptional vision, along with their long, sharp talons, make them very effective predators. An eagle will make screeching sounds to warn predators not to venture into their territory. This noise is also used to deepen the bond between the male and female. Bald eagles primarily eat fish and carrion, but they also eat ducks, snakes, other small birds, reptiles, and small mammals. Bald eagles have even been known to kill young deer and adult raccoons.
Bald Eagle Facts & Trivia
- Male bald eagles weigh between 7 and 10 pounds. Females are considerably larger, weighing up to 14 pounds.
- Eaglets and juvenile bald eagles are brown in color, with some white feathers. They do not get the distinct coloration of a mature bald eagle until they are about 4-6 years old.
- Bald eagles are capable of carrying a little more than half their own weight in flight, up to 8 pounds.
- Bald eagles are exceptional swimmers. If they catch a fish which is too big for them to carry in flight, they will swim with it to the shore.
- Bald eagles require old-growth forests of coniferous or hardwood trees for perching, roosting, and nesting. They will often build their nests in trees that have good visibility of a nearby waterway.
- Most bald eagle fatalities are either directly or indirectly human related. Common causes of death are trauma cause by impact with man-made structures, gunshot, poisoning, trapping, and electrocution.
- In the mid-20th century, bald eagles numbers severely dropped due in part to the use of the pesticide DDT. DDT interfered with the bald eagle's calcium metabolism, which made eggshells too brittle to withstand the weight of a brooding adult.
- After Bald eagles were protected through the Endangered Species Act of 1966, and DDT was banned in 1972, bald eagle numbers dramatically shot up. In 2007, the bald eagle was removed from the list of protected and endangered species.

Bald Eagle Habitat
Bald eagles are found only on the continent of North America. They prefer to inhabit areas near large, open bodies of water such as lakes, rivers, wetlands, and ocean coasts. By living near water, they can easily find food. Eagles will migrate in order to find temperate environments. In northern regions, they will travel south in the winter to avoid the chill. In southern regions, they will migrate northwards to escape extreme heat. Eagles build large nests in the forks of tall trees or along cliff faces. They return to the same nesting site each year, adding new materials to the previous year’s nest. A bald eagle’s nest can reach ten feet across and weigh up to 2,000 pounds.
Bald Eagles In United States History
Bald Eagle Information For Kids
- In 1776, the eagle began to appear on coins in the United States.

- The topic of what the national emblem of the United States of America should be was disputed over for more than six years.
- Benjamin Franklin was a prominent opponent of the bald eagle being chosen as the national bird of the United States. In a letter to his daughter, Franklin wrote that the bald eagle was a 'a bird of bad moral character. He does not get his living honestly.' Franklin thought that because the Bald Eagle robbed other birds of their prey, and because the eagle would flee instead of fight when mobbed by sparrows, that the bird was a poor choice. He wrote that the wild turkey, another bird native to North America, would have been more representative of the United States, because although the turkey was a little vain and silly, it was a bird of courage, because the turkey would not hesitate to attack British troops that invaded his farm yard with a red coat on.
- In 1789 Congress chose the bald eagle to represent the nation, and since then it has been the national emblem of the country.
- It was chosen as the national bird of the U.S. because of its majestic beauty, strength, grace, long life, spirit of independence, and loyalty. It was also chosen because it is native to North America.
