Eagles

Eagles are iconic raptors known for their impressive size and formidable hunting prowess. These apex predators possess large, hooked beaks designed for tearing flesh, powerful talons for gripping prey, and extraordinary vision that allows them to spot potential meals from great distances. Their keen eyesight is up to eight times sharper than that of humans, enabling them to detect prey from high altitudes. Eagles are found across diverse habitats, from lush rainforests to expansive grasslands. The Bald Eagle, a symbol of national pride in North America, and the Golden Eagle, known for its agility and strength, exemplify the diverse adaptations of eagles.

Bald Eagle

Bald Eagles (Haliaeetus leucocephalus) are majestic birds of prey known for their striking appearance and symbolic significance. As the national bird and symbol of the United States, they are easily recognized by their white heads and tails contrasting with their dark brown bodies and wings. These large raptors have a wingspan of up to 7.5 feet, making them impressive in flight.

Bald Eagles are found near large bodies of open water with abundant fish, their primary food source. They prefer habitats such as coastlines, rivers, lakes, and marshes where they can hunt for fish, waterfowl, and small mammals. Nesting in tall trees or cliffs, they build massive nests that they often reuse and expand each year.

Bald Eagles go through four maturation stages. Each stage takes one year. The first stage occurs when they hatch, they have dark eyes, pink skin, and flesh colored talons. Within the first 18-22 days their skin turns bluish in color and their legs turn yellow. Within the first year, they will develop white feathers and their beaks and eyes will turn dark brown. In the second stage, their eyes turn grayish brown and their feathers become more mottled white. In the third stage, their eyes and beak turns yellow. During the fourth and final stage, their body feathers are mostly dark/brown while their head and tail remain white. Their adult plumage is achieved in their fifth year of life. Females are larger than males. They can live up to 28 years in the wild.

Habitat/Range:

These birds are native to North America and prefer areas near large bodies of water. They are very skittish and will avoid areas where humans are present.

Size:

Length: 31-37in. Wingspan: 70-90in. Weight: 9.5lbs.

Bald Eagles can go several days without eating. They will even store food in their crop for later digestion.
They have a 6 foot wing span and are mostly scavengers.
Bald eagles build the largest nest of any North American bird.
The grip of a bald eagle talon is 10x stronger than that of humans.
Bald eagles are not actually bald. Their heads are covered in white feathers. The name comes from an older meaning of the word "white-headed".
Eagle eyes are the same size as a human's. Their vision is so precise, they can spot prey up to 2 miles away.
Bald eagles return to the area they were born when they reach reproductive maturity and mate for life.

Conservation efforts have played a critical role in the recovery of Bald Eagle populations. Once endangered due to habitat destruction, illegal shooting, and the effects of DDT pesticide, they have made a remarkable comeback thanks to legal protection, habitat restoration, and banning harmful chemicals. Today, Bald Eagles serve as a powerful reminder of successful wildlife conservation efforts.

Conservation Action:

Protected under the Migratory Bird Act. Some areas have habitat conservation plans in action.

Owls

Owls are unique among raptors for their nocturnal hunting adaptations. With large, forward-facing eyes and exceptional hearing, owls are masters of night-time predation. Their large eyes provide excellent low-light vision, while their highly sensitive ears, often aided by facial discs that funnel sound, allow them to locate prey in near-total darkness. Owls also have specialized feathers that enable silent flight, reducing noise and making them almost invisible to their prey. This silent flight is achieved through a combination of unique feather structures that minimize air turbulence. The Barn Owl's heart-shaped face enhances sound detection, and the Great Horned Owl's tufted feathers contribute to its distinctive appearance and auditory capabilities. There are over 200 owl species worldwide, each adapted to its specific habitat, from dense forests to urban areas.

Barn Owl

Barn Owls (Tyto alba) are captivating nocturnal birds of prey known for their distinctive heart-shaped faces and silent flight. These owls are widely distributed, found on every continent except Antarctica. They typically inhabit open countryside, grasslands, and farmlands, where they roost in barns, tree cavities, and other secluded places.

Barn Owls are remarkable hunters, relying on their acute hearing and keen eyesight to locate prey, primarily small mammals like mice and voles. Their silent flight is facilitated by specialized feather structures that reduce noise, allowing them to stealthily approach their prey.

These owls play a crucial role in controlling rodent populations, making them valuable allies to farmers and an integral part of the ecosystem. Unfortunately, Barn Owl populations face threats from habitat loss, pesticide use, and road collisions.

Here at the Little Rock Zoo you can see the Barn Owl in the Arkansas Heritage Farm.

The Barn Owl has excellent low-light vision, and can easily find prey at night by sight. But its ability to locate prey by sound alone is the best of any animal that has ever been tested. It can catch mice in complete darkness in the lab, or hidden by vegetation or snow out in the real world.
The oldest known North American Barn Owl lived in Ohio and was at least 15 years, 5 months old when it died.
It does not hoot, a call often made by other owls, instead they produce a characteristic rasping screech.
The barn owl has acute hearing, with ears placed asymmetrically for improved detection of sound position and distance, and it does not require sight to hunt.
Owls eat their prey whole but cannot digest bones, beaks, feathers, fur and claws; these materials are regurgitated several hours after eating in the form of ‘owl pellets’.

Barn Owls are listed as least concern by the IUCN. They are relatively common throughout most of their range and a 2012 census reported that their population is at about five million adult individuals. Although they are not considered globally threatened, their numbers have been declining in parts of their rage primarily due to habitat loss. Pesticide use, prey depletion and traffic deaths are also threats.
