Bird is a feathered, two-legged, winged, egg-laying, warm-blooded vertebrate. They are characterized by their feathers, the hard-shelled laying eggs, a beak without teeth, a four-chambered heart, a high metabolic rate, and a lightweight but with strong skeleton. They have more or less feathery wings; the only known species without wings are THE MOA. Wings are evolved fore-limbs, the most of the bird species can fly however flightless birds include penguins, ratites, and diverse endemic island species. Some species of birds, like penguins and duck family are adapted for swimming. Birds also have respiratory and digestive systems that are only adapted for flight. Some birds, especially parrots and corvidae are among the most intelligent one; …show more content…
For better understanding the immense diversity of bird species it is useful to examine the main groups of birds. Many kinds of birds yearly migrate great distances. They are social; communicate with visual calls, signals, and songs, and participating in social behaviors as cooperative breeding. There are many different ways people studies and classified the birds into subgroups. Majority of bird species are socially monogamous maximum for year, but rarely for their entire life. Other species have polygynous (many females) or, rarely, polyandrous (many males) breeding systems. Most of the birds have a long duration of parental care after hatching the eggs which they usually laid in a nest and incubate.
Many species of the birds are economically important like domesticated birds and undomesticated birds (poultry and game) are important sources of meat, eggs, and feathers. Few of them are popular as pets for example songbirds, parrots, and other species. Guano is harvested for use as a fertilizer. About 120 to 130 species have become extinct due to human activity since the 17th century and hundreds earlier. Human activities threaten about 1200 bird species with extinction however the efforts are underway to protect
The evidence clearly indicates that this theropod had lung and respiratory mechanics similar to that of a crocodile—not a bird. There was evidence of a diaphragm-like muscle separating the lung from the liver, much as you see in modern crocodiles. These observations suggest that this theropod was similar to an ectothermic reptile, not an endothermic bird. Did feathered dinosaurs exist?
A significant motif of The Painted Bird is the comparison between the primitive aspects that the boy experiences in the countryside that contrast his upbringing in civilization. The child’s strongest memory of his past life is his “appendix operation when [he] was only four years old” (Kosinski 10). There he had access to modern medicine and recalls “the glossy hospital floors, the gas mask doctors placed on my face” (Kosinski 10). This directly contrasts with his experiences in village life. During his time with the village healer, Olga, the boy witnesses the many rituals she uses to heal people.
The Northern Spotted Owl is currently classified as threatened and is currently undergoing conservation efforts in order to bring its population numbers back up. The Northern Spotted owl is the largest of the three subspecies of spotted owls. They are medium sized, dark brown owls with barred tails and white spots on their head and breast. The males are slightly larger than the females and are often confused with the barred owl. They are primarily nocturnal but still forage opportunistically during the day.
Bald eagles are found in many environments in the United States. Those environments include deserts, mountains, freshwater, and marine areas. Bald eagles are known to build very large nests in treetops and always near water. The main source of food for bald eagles is fish, but they will sometimes eat other small animals.
Moreover, nest sites can be large and are often found in the taller trees high above ground and atop high cliff ledges. The nests are bowl shaped and are made up of sticks and leafy green branches measuring up to 6.5 feet high and 3 feet across with both male and female contributing in the construction of the nest. Fundamentally, the nests are made high above ground where they can have a dominant perspective of their surrounding landscape. Female Red-tailed hawks usually produce 1 to 5 eggs with an incubation period of between 28 to 35 days and a nestling period of between 42-46 days. The female stays with the young during the first week while the male brings the food to the nest.
Turkeys are the smartest animals there is in my opinion other than a dog, they cover the most ground other than a coyote. They roost where no other animals can get them. They know when they see something that they do not like. They will either run or fly or stay there where nothing can see them. In the fall time all the gobblers stay together in groups and all the hens stay together in a group.
Natural selection is seen in the finches that Darwin studied on the Galapagos Islands. Environment and food supply changes caused the finches beaks to adapt in a unique way. Studies on Darwin’s finches show us that natural selection in a natural environment is interpretable, observable, and repeatable (Grant, 2003). Natural selection is representable in different types of birds such as the Island Scrub-jay. A study published in 2015 on these Island Scrub-Jays (Aphelocoma insularis) demonstrates examples of natural selection.

In the story, “on Birds, Bird Watching and Jazz” by Ellison, the interesting theory as to how Charles Porter Jr. got his nickname as “Bird “ is told using humor in his stories along with a careful choice of syntax and his diction. In the first paragraph, the author uses alliteration,”...and despite the crabbed and constricted character…” to give us an insight on the figure he is speaking about. The author also chooses these words to build up an impression and then breaks it by saying Parker was a most intensive melodist. In the second paragraph of this story, Ellison establishes what a nickname does and how it would originate. Continuing on, Ellison introduces a new fact to the audience, that jazzmen were labeled as cats because they were legends.
When insects became abundant, finches have developed smaller and longer beaks.
Australia is home to diverse fauna and flora, many of them are on the brink of extinction. Unfortunately, Orange-bellied parrots is one of them, it’s time for Aussie to start saving these beautiful creatures. The Orange-bellied Parrots Many of the Victorian animals are under extreme threats due to human over exploration, a lot of these lovely, harmless animals are on the way to extinction or it has already extinct in the wild. The orange-bellied parrots (Neophema chrysogaster, under the family of Psittacidae) are now critically endangered and listed under the Environment Protection and Biodiversity Conservation Act 1999.
Birds are gifted with the extraordinary ability to fly. Their wings propel them above the ground and over people below. They are able to view the world from an angle that no one else gets to see. This is what makes birds and wings such powerful symbols in literature. These symbols characterize characters, move the plot and develop one more of the book’s ideas.
National Wildlife Federation is a wildlife organization founded by Ding Darling. The Wildlife Federation works to protect the ecosystem that is crucial to the native wildlife. The National Wildlife Federation took part in the passing of clean water act, clean air act, and endangered species act. In 2007 the water resources development act was successfully passed thanks to the help of the Wildlife Federation.
“Caged Bird” written by Maya Angelou in 1968 announces to the world her frustration of racial inequality and the longing for freedom. She seeks to create sentiment in the reader toward the caged bird plight, and draw compassion for the imprisoned creature. (Davis) Angelou was born as “Marguerite Annie Johnson on April 4, 1928 in St Louis, Missouri”. “Caged Bird” was first published in the collection Shaker, Why Don’t You Sing? 1983.
Animals in Their New Natural Habitat Why are different species becoming extinct? Do researchers know how many innocent animals are killed each year? When will animals be protected in a comfortable habitat? In man-made environments, such as zoos and other nature parks, animals that are born in the wild are protected and well taken care of. Due to animals running around in the wild, scientists and researchers can track the amount of animals being killed everyday.
