That’s why they tend to hang around garbage dumps (a great place to take your friends birding). The tail is moderately long and slightly wedge-shaped. Birds. [47], In Florida, nesting habitats often consist of mangrove swamps, the shorelines of lakes and rivers, pinelands, seasonally flooded flatwoods, hardwood swamps, and open prairies and pastureland with scattered tall trees. While common loons normally avoid conflict, they are highly territorial and will attack predators and competitors by stabbing at them with their knife-like bill; as the range of the bald eagle has increased following conservation efforts, these interactions have been observed on several occasions, including a fatality of a Bald eagle in Maine that is presumed to have come about as a result of it attacking a nest, then having a fatal puncture wound inflicted by one or both Loon parents. An adult bald eagle can lift & fly w about four (4) pounds depending on the circumstances. Eagles have structures on their toes called spicules that allow them to grasp fish.

Occupying varied habitats from the bayous of Louisiana to the Sonoran Desert and the eastern deciduous forests of Quebec and New England, northern birds are migratory, while southern birds are resident, remaining on their breeding territory all year. Tree species reportedly is less important to the eagle pair than the tree's height, composition and location. There is video from about a year ago of a dead fawn hanging over a power line w a bald eagle nearby. It may swim to safety, in some cases pulling the catch along to the shore as it swims,[102] but some eagles drown or succumb to hypothermia.

[111], The bald eagle is thought to be much more numerous in North America than the golden eagle, with the bald species estimated to number at least 150,000 individuals, about twice as many golden eagles there are estimated to live in North America. In 1930 a New York City ornithologist wrote that in the state of Alaska in the previous 12 years approximately 70,000 bald eagles had been shot. For a scavenger like the bald eagle, a seal or deer carcass would be an unexpected large food supply.

If its territory has access to open water, it remains there year-round, but if the body of water freezes during the winter, making it impossible to obtain food, it migrates to the south or to the coast. [51][55] Eggs in Alaska averaged 130 g (4.6 oz) in mass, while in Saskatchewan they averaged 114.4 g (4.04 oz). [50], While wintering, bald eagles tend to be less habitat and disturbance sensitive. The flight includes swoops, chases, and cartwheels, in which they fly high, lock talons, and free-fall, separating just before hitting the ground.

[61] Bald eagles also regularly exploit water turbines which produce battered, stunned or dead fish easily consumed. [43] The young eaglets pick up and manipulate sticks, play tug of war with each other, practice holding things in their talons, and stretch and flap their wings. The medicine man touches the fan to the center pole and then to the patient, in order to transmit power from the pole to the patient.

[43] Healthy adult bald eagles are not preyed on in the wild and are thus considered apex predators. [132] In one case, an adult eagle investigating a peregrine falcon nest for prey items sustained a concussion from a swooping parent peregrine, and ultimately died days later from it. [100] It has been estimated that the gripping power (pounds by square inch) of the bald eagle is ten times greater than that of a human. Female eagles laid eggs that were too brittle to withstand the weight of a brooding adult, making it nearly impossible for the eggs to hatch. The closely related African fish eagle (Haliaeetus vocifer) (from far outside the bald eagle's range) also has a brown body (albeit of somewhat more rufous hue), white head and tail, but differs from the bald in having a white chest and black tip to the bill.

Wyoming eagles may inhabit habitat types ranging from large, old-growth stands of ponderosa pines (Pinus ponderosa) to narrow strips of riparian trees surrounded by rangeland. Gorging allows the bird to fast for several days if food becomes unavailable. [44][45] Trees used for nesting in the Greater Yellowstone area average 27 m (89 ft) high. Rich in … Today, the contiguous state with the largest number of breeding pairs of eagles is Minnesota with an estimated 1,312 pairs, surpassing Florida's most recent count of 1,166 pairs.

The bald eagle is an opportunistic feeder which subsists mainly on fish, which it swoops down and snatches from the water with its talons. [8][42], The bald eagle is a powerful flier, and soars on thermal convection currents. [21] Wintering bald and golden eagles in Utah both sometimes won conflicts, though in one recorded instance a single bald eagle successfully displaced two consecutive golden eagles from a kill.

[93] In landlocked areas of North America, wintering bald eagles may become habitual predators of medium-sized mammals that occur in colonies or local concentrations, such as prairie dogs (Cynomys) and jackrabbits (Lepus). [171], During the Sun Dance, which is practiced by many Plains Indian tribes, the eagle is represented in several ways. During or after preening, birds like to shake off. DDT itself was not lethal to the adult bird, but it interfered with the bird's calcium metabolism, making the bird either sterile or unable to lay healthy eggs.
