The U. S. Capital and its bird

It's hard to believe we were going to choose the turkey over this distinguished looking
bird.  This is a serious looking creature.  It says don't mess around with me - I am very proud.  I was lucky to get to visit our nation's capital this summer and help make decisions on what we would like our National Education Association to do and endorse this coming year.  I was a part of 11,000 delegates from all over our country listening to debate and making decisions.  I learned first hand how a caucus works.  We also had people come talk to us - the Vice President and his wife, the Teacher of the Year, and even President Obama via phone.  It was 10-12 hour days with fun activities in the evenings.  I even got to see the 4th of July fireworks over the Capitol.  What an experience!  Well, on to some information about eagles.  I actually took this picture in Ft. Collins, Co.

Description

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.[2] 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.[3][4]
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.[5][6]
Among the eagles are some of the largest birds of prey: only the condors and some of the Old World vultures are larger. It is regularly debated which could be considered the largest species of eagle. They could be measured variously in total length, body mass or wingspan. Different lifestyle needs among various eagles result in variable measurements from species to species. For example, many forest-dwelling eagles, including the very large Harpy and Philippine Eagles, have relatively short wingspans, a feature necessary for being able to maneuver in quick, short bursts through dense forested habitats.[7] On the other hand, eagles in the genus Aquila are found almost strictly in open country, are superlative soarers, and have relatively long wings for their size.[7]
Here are lists of the top five eagles going on weight, length and, lastly, wingspan. Unless otherwise noted via reference, the figures listed are the median reported for each measurement in the guide Raptors of the World (Ferguson-Lees, et al.), in which only measurements that could be personally verified by the authors were listed.[7]
This information comes from Wikipedia and, of course, we know this is a bald eagle.
