They also eat waterfowl, shorebirds, colonial waterbirds, small mammals, turtles, and carrion often along roads or at landfills. Because they are visual hunters, eagles typically locate their prey from a conspicuous perch, or soaring flight, then swoop down and strike.

Bald eagles require a good food base, perching areas, and nesting sites. Their habitat includes estuaries, large lakes, reservoirs, rivers, and some seacoasts. In winter, the birds congregate near open water in tall trees for spotting prey and night roosts for sheltering. Eagles usually mate for life, choosing the tops of large trees to build nests, which they typically use and enlarge each year.

Bald eagles may also have one or more alternate nests within their breeding territory. In treeless regions, they may also nest in cliffs or on the ground. The birds travel great distances but usually return to breeding grounds within miles of the place where they were raised. Bald eagles generally nest near coastlines, rivers, and large lakes where there is an adequate food supply.

They nest in mature or old-growth trees, snags dead trees , cliffs, and rock promontories. Recently, and with increasing frequency, bald eagles are nesting on artificial structures such as power poles and communication towers, and away from large water bodies. In forested areas, bald eagles often select the tallest trees with limbs strong enough to support a nest that can weigh 1, pounds or more.

Nest sites typically include at least one perch with a clear view of the water, where they forage. Eagle nests are constructed with large sticks, and may be lined with moss, grass, plant stalks, lichens, seaweed, or sod. Bald eagle nests are generally feet wide and feet deep, although the nesting pair will add nesting material to the nest every year.

Some eagle nests stay small, but some can reach 10 feet across and weigh a thousand pounds! Many eagles that are not called "fish-eagles" still hunt fish, many eagles not called "hawk-eagles" can still look similar to hawks, and many eagles not called "snake-eagles" will prey on any snakes they can catch.

Because these birds have wide ranges, it is also common for a single eagle species to have several different common names, each of which may highlight a different characteristic or trait. Because common names can be so widely varied and confusing, learning and using birds' scientific names to note individual species is always a good idea for official lists and records.

Bald eagles are choosing to nest close to human activity, but no one knows why. When the federal government released its last population estimate, which used data from , there were believed to be just over 72, birds. Across the U.

In recent years, the booming eagle population has led the birds to increasingly take up residence in more urban areas. A pair of bald eagles nested in a pine tree on the side of Highway 39 in the San Gabriel Mountains in , drawing crowds of enthusiastic and sometimes overly aggressive bird watchers.
