Bird Characteristics - Animals and Wildlife - About.com Birds are unmatched in their command of the skies. Albatrosses glide long distances over the open sea, hummingbirds hover motionless in mid-air, and eagles swoop down to capture prey with pinpoint accuracy. But not all birds are aerobatic experts. Some species such as kiwis and penguins, lost their ability to fly long ago in favor of lifestyles suited more for land or water. Birds are vertebrates, which means that they are among those animals that possess a backbone. They range in size from the minute Cuban Bee Hummingbird (Calypte helena) to the grand Ostrich (Struthio camelus). Birds are endothermic and on average, maintain body temperatures in the range of 40Â °C-44Â °C (104Â °F-111Â °F), though this varies among species and depends on the activity level of the individual bird. Birds are the only group of animals to possess feathers. Feathers are used in flight but also provide birds with other benefits such as temperature regulation and coloration (for display and camouflage purposes). Feathers are made of a protein called keratin, a protein that is also found in mammalian hair and reptilian scales. The digestive system in birds is simple but efficient (enabling them to pass food through their system quickly to minimize the extra weight of undigested food and the time it takes to extract energy from their food). Food travels through the parts of a birds digestive system in the following order before it is excreted: esophagus - narrow tube that carries food to the crop crop - a sack-like widening of the digestive tract where food can be stored temporarily proventriculus - the first chamber of a birds stomach where food is broken down by digestive enzymes gizzard - the second chamber of a birds stomach where food is ground up by muscular action and small stones or grit (ingested by the birds) intestines - tubes that continue to extract nutrients from food after it has passed through the gizzard Refs: Attenborough, David. 1998.

Essay on Women and Men in the US

Essay on Women and Men in the US Essay on Women and Men in the US Example essay: Major issues facing women and men in the U.S. today There are very many issues that are facing both men and women in the U.s today. The effects are far reaching although others do not have very significant outcomes. Gender disparity is mong the major issues that are known to affect people in the U.S. The population in the United States has been established to be having many women than men. However, this is not depicted in the public area. The Supreme Court for instance has a higher male population than women. The country? presidents from Regan to Obama have tried to eliminate this disparity by making special appointments of females judges into the Supreme Court. Another issue that is facing men and women in the U.S is the one that pertains to abortion. Facts, information and statistics about abortion and pregnancy in the U.S place a lot of evidence on teens being the most affected. There have been increased cases of sexual assault, rape, prostitution and domestic violence. In one way or another, either a man or a woman is being victimized. In many occasions, it is women who fall victim due to the notion by the society that they are a weaker sex. There are facts, statistics and stories that surround abuse and survival together with the appropriate ways that can be adopted to reduce these forms of abuse. In all creations, all people seek for love and intimacy. Yet, it is becoming evident that neither of them is a certain thing. People are different; some seek for soothe and stability while others have the desire for excitement and experimentation. As humans, we may know one another, but it is also a fact that it takes two to tangle. Currently, the issues that pertain to women? reproductive rights and the diverse forms of contraception are widely and legally accessible to all women in the U.S. Other issues that have been seen to affect people in the U.S are those that are linked to pay equity, healthcare, and leadership, feeding habits, obesity and citizenship. All these factors have a way in which they affect the people. What is important though is how the society approaches and tries to find solutions towards solving them in a more amicable manner. I would say that there are many problems that face men and women in the United States just like any other country of the world whether developed or not developed. In comparison to the less developed countries and more specifically those that are non-democratic, America is more dwarfed in the way her people are faced with the problems. Some of the problems are as a result of the religious doctrines that permeate abuse and pose subservient regulations on those who are linked to social problems. Sometimes, it becomes very hard to contemplate on the traditional, feminist issues and think of obtaining a female president in the U.S unless more women and men start cherishing diplomacy endowed with more actions and soft power. Such issues can also be overcome if more women get involved in business activities and political positions so that their voices, votes and plans can be felt. An opinion I have held over time now is that gender issues will always continue to be factors in social interactions. This is due to the loopholes that the society has allowed to prevail. For instance, the feminist issues that are still being talked about in the current society are majorly applicable to those who are aware and relish freedom. It is also appropriate for those who want a gentler and comfortable society. Although the U.S is in pursuit of these key factors, it is none the less faced with issues of gender disparity and discrimination. To make sure that gender issues are eliminated, then it is imperative that all of us exert positive influences that will terminate the undercutting on one another. It is also very vital that the society learns to have faith on one another. It should also develop an innate belief in the ability of women to lead in a diligent way. The society should also make sure that it rises up an entity and extends its hand throughout the aspects of develo pment in the spirit of change that will impact positively on the lives of our sisters, not only in the United States but also to the rest of the world.
