= = = We learn about the world through our senses -- sights, sounds, smells, touch, and how things make us feel. If we want to learn about a particular person, place or thing, we might go to an encyclopedia or look at a photograph. But if we wish to EXPERIENCE this subject, perhaps a creative writer or poet is our best resource. = = = = Below, see what you might find if you were trying to learn about eagles. Notice how each type of resource -- the encyclopedia entry, the photograph, and the poem -- informs us about different elements of the eagle. Clearly, depending upon our purpose and needs for this research, each resource may or may not be helpful. How does each of the 3 resources inform us about eagles differently? =

===Eagles are large, powerfully built [|birds of prey], with a heavy head and beak. Even the smallest eagles, like the [|Booted Eagle] (//Aquila pennata//) (which is comparable in size to a [|Common Buzzard] (//Buteo buteo//) or [|Red-tailed Hawk] (//B. jamaicensis//)), have relatively longer and more evenly broad wings, and more direct, faster flight (despite reduced size in aerodynamic feathers). Most eagles are larger than any other raptors apart from some [|vultures]. The smallest species called eagle is the [|South Nicobar Serpent Eagle] (//Spilornis klossi//), at 450 g (1 lb) and 40 cm (16 in). The largest species are discussed below. Like all birds of prey, eagles have very large hooked [|beaks] for tearing flesh from their prey, strong muscular legs, and powerful [|talons]. The beak is typically heavier than most other birds of prey. They also have extremely keen eyesight (up to 3.6 times human acuity for the [|martial eagle]) which enables them to spot potential prey from a very long distance. This keen eyesight is primarily contributed by their extremely large pupils which ensure minimal [|diffraction] (scattering) of the incoming light. The female of all species of eagle known are larger than the male.===

===Eagles normally build their nests, called [|eyries], in tall trees or on high cliffs. Many species lay two eggs, but the older, larger chick frequently kills its younger sibling once it has hatched. The dominant chick tends to be the female, as they are bigger than the male. The parents take no action to stop the killing. Due to the size and powerful of many eagles, they are ranked at the top of the food chain as [|apex predators] amongst the avian world.===
