Hummingbirds are stunning creatures, but their future can be bright only if they have plenty of flowers for food and trees for shelter. Unfortunately, human population grows too fast for the hummingbirds' habitats. Once a person knows more about these charming animals, they will find the forests a richer place to protect. Hummingbirds are the smallest and most brilliantly colored birds. Their aerial maneuvers fascinate all.
Hummingbirds are promiscuous animals, and families generally consist of a single mother and two baby chicks. It all starts during mating season, when a male tries to attract a female. He may hover in front of her showing off his gorgeous wings, tail, beak and plumage. If she isn?t interested she just flies away. If he wins her affection, they will sleep together one night. In the morning they?ll fly away in separate directions and probably never meet again.
Males obviously take no part in raising the young. Two white pea-sized eggs are generally laid, several days apart. The hummingbird mother works very hard to care for her young. The two chicks are born naked, blind, and smaller than bumblebees, but they grow quickly. By the time they are three to four days old, their eyes open, and the mother continues feeding them. The duration of nesting period is fourteen to thirty-one days depending on the food available and the strengths of the chicks and the mother. When they are ready for fledging, the chicks may be 4.5 grams while their exhausted mother is down to 2.5 grams after the feat of raising her young.
After a month or so, the hummingbirds leave their nest and master flying quickly and easily. They are continued to be fed because they end up wasting a lot of time mistaking hats, signs, and other bright objects for flowers.
The average life span of a hummer is probably three to five years. The record has been twelve years. There are about three-hundred and twenty different species, and the Bee Hummingbird is the smallest. 8 cm is not only half of the length of my pen, but also the length of the largest hummingbird, the Giant Hummingbird.

Flying Tigers is the name of a mercenary group of American pilots that helped defend China and the Burma Road from the bombing of the Japanese during World War II. The name of their planes was Tomahawks, but the Chinese called them Fei Hu for the sharks teeth painted on their planes.

In Cold Mountain and "A Poem for the Blue Heron", tone is established in a multitude of ways. These two pieces of literature describe the characteristics and actions of a blue heron, both aiming for the same goal. However, Charles Frazier and Mary Oliver approach their slightly differing tones employing organization, metaphoric language, and diction.
The birds show symbolism in more than one way throughout the text. As the soldiers are travelling from all over the world to fight for their countries in the war, the birds are similarly migrating for the change of seasons. The birds however, will all be returning, and many of the soldiers will never return home again. This is a very powerful message, which helps the reader to understand the loss and sorrow that is experienced through war.

The piping plover usually nests on the sandy beach, some distance away from the water and is often located near a large rock or clump of grass. There are usually 4 eggs in the nest. The eggs begin to hatch for 25 to 30 days.
“It is my conviction that killing under the cloak of war is nothing but an act of murder,” Albert Einstein. The Vietnam War was a war that America did not need. America believed they were doing good. They believed that they were protecting the people of Vietnam. America did not realise that they were only making a bad situation worse. America stopped nothing. They didn’t stop communism; they didn’t save the people of Vietnam. America caused the number of casualties in Vietnam to increase and had their own people killed. They caused diseases and destroyed the environment with the help of Agent Orange. America sent soldiers on a mission with a result of hundreds of civilians murdered. America did not help anyone. America sent people out to murder others and to be killed in the line of duty.
The frightening truth is our little pollen buddies are losing their numbers by the millions. Bees are essential to the ecosystem, mainly due to the pollination that they provide to many crops ( “ First” ). Bees pollinate during most of their life which is why they are so vital for most crops to produce seeds. They have hairs on their legs which, gather the pollen on the crops and allow for viable seeds. While some plants can pollinate through other natural ways, a study in the United States concluded that “39% of crops were highly dependent on bees for pollination” ( “First” ). Considering the amount of food that we as

Dead Birds This movie is about a tribe on the island of Papa New Guinea. They are called the Dani. This tribe lives in the middle of the island. Near their enemy, another near by tribe. They live in little huts made from mud and wood.
Hummingbirds rely on plant nectar to supply the necessary energy for their highly energetically and expensive flying and feeding behaviors. Hummingbirds obtain energy from the nectar of flowers using their tongue and it is thought that up to half of the tongue is made up of cartilage making it easier to direct and control and in turn more efficiently eat. (Tamm, Gass 1986). Hummingbirds have the ability to drink their own weight in nectar only in a matter of hours (Tamm, Gass 1986) and in order to meet their daily energetic needs they must visit several thousand flowers a day (Tamm, Gass 1986).
Honey Bee Population Decline Daisy Childs 11-20-14 Professor Garcia ENG 1027. INTRODUCTION: Apis mellifera, commonly known as the honey bee, are solely responsible for pollinating one-third of the world’s crops, and they are in danger of dying off, according to the article “Natures Dying Migrant Worker,” written by Josephine Marcotty for the Star Tribune. This honey bee population decline poses a huge threat to our environment, farmers, and economy. It is assumed by BBC News writer Zoe Gough in her article,"Wild Honey Bees: Does Their Disappearance Matter?" that all of the wild honey bees in England and Wales are gone.

When the colony becomes well established, the queen begins to lay some eggs that develop into queens and males. It takes a few years before a colony becomes large enough to send out winged males and young queens to start new colonies. The cycle will now begin all over again. Nests come in all shapes and sizes. One tropical species built a nest that extended forty feet below the surface of the ground.
