California condor, the largest flying bird in North America area, is now defined as endangered species. The term endangered species refer to species threatened with extinction by changes in its environment. The condor as scavengers, no matter how dangerous they may sound, are the essential member of our ecosystem (Verner, 1978). However, the population of the California condors decreased tremendously during the late 1970s, with only 22 reported alive worldwide in the year 1982-1983 and only nine in the wild by 1985. It was the lowest recorded number of this creature (Church, 2006). And the habitats also shrunk from several locations to only California area. The Condor was then added to the endangered species list of the United States. Moreover, Condor comes under the category of critically endangered (CR) species which is the most severe category under conservation status subjected to species at the highest risk of extinction. Since then various organizations and societies are working on conserving this creature and bringing it back to wildlife.(USFWS, N.D.) Condor that people talks about can be classified into two categories: Andean condor of South America and California condor of North America. Although they classified into two genera, they are close enough to have a similar ecology. Andean Condors are …show more content…
California condor is also black with very fewer feathers. The color of its’ bald head, which equipped with a pair of reddish brown eyes, varies from white to purple. Unlike Andean Condor who has a grayish white lining on their wings, California condor has bold white coatings at their underwings area (Houston, 2001). The weight of this massive creature is around 18lbs to 31lbs while a fully-grown-up adult California condor can stretch its wings to about 2.7 meters compare to 3.2 meters for Andean condor. It can fly as high as 4,600 meters (15,000
Mutualistic relationships occur between eagles and farmers when farmers begin to plant crops in their fields. When crops are planted, prey are attracted to the field to eat. Bald eagles will surround fields to prepare to eat the prey that come in. The eagle will eat the prey that are coming into the field benefiting it by providing energy to the bird, and the farmer benefits because his crops are protected and have the ability to
The bald eagle (Haliaeetus leucocephalus) is a bird of prey and is most commonly found in North America. Its habitat is anywhere near large areas of water surrounded by many tall trees. They feed mainly on fish, which they grab from the water with their talons. Due to human impact, particularly from the use of guns, the bald eagle has faced extinction.
The population of the whooping cranes most definitely gets affected from precipitation, because the population gets affected negatively with high precipitation levels present, while positively with low precipitation levels. The population of the whooping cranes gets affected this way because if there were high precipitation levels for a year, the hatching success rate drastically decreases from the precipitation, who damages the eggs laid by the cranes. By either breaking the eggs, making the cranes not be present to incubate their eggs, or actually destroying the birds’ nests. Also, the high precipitation levels may even cause a few fatalities, which is a very serious problem involving this particular endangered species. While with low precipitation
Of the birds of Arizona, the cactus wren is likely to be the most well known, as it is the state bird. The cactus wren is a very vocal bird with the white eye stripes behind each of it’s eyes. Its breast is heavily flecked with dark brown and black, whilst its tail feathers alternate between black, brown and white. Its beak also has a faint curve to it. The cactus wren makes its home in a variety of desert environments, most commonly in the foothills with all manner of scrub such as yucca, mesquite, and its namesake, cactus. One of the most numerous birds of the city is quail who tend to live in washes and bushes as they are often too heavily weighted to fly far off the ground or for long distances. The Northern mockingbird also
The condor will eat anything from the remains of a deer, to a large marine mammal like a whale. “California condors can soar on warm thermal updrafts for hours, reaching speeds of more than 55 miles per hour and altitudes of 15,000 feet with flights up to 150 miles. Condors hold their wings in a horizontal position and fly very steadily.” (Calvin & Rosanna Hamilton, 2005-2008) California condors mature and reproduce slowly.

In 1782, the bald eagle was elected as the national symbol of the United States of America, yet by the early 1960’s, it was nearly extinct in the Continental United States. A combination of many dangers, with the main danger being the pesticide DDT, the bald eagle was on the verge of extinction. Yet, through conservation measure applied by the United States government the bald eagle cam back from the brink and was taken off of the endangered species list in 2007.
(Kuipers) Luckily, as the years grew Californians started to find sea otters roaming out in the water again. Slowly but surely the population was growing in these recovering areas, but the southern sea otters (Enhydra lutris nereis), also known as California sea otters, were listed as threatened in 1977 under the Endangered Species Act. (Carswell) There are a number of reasons for why sea otters have come close to extinction.

The California’s symbols were designed by the Great Gold Rush. First, the California State mammal is the Grizzly bear. Before the bears with destroyed, they lived in valleys and mountains in California. Impressively, when the settlers came, the bears did not run they lived off the people's livestock and resources. Sadly, the last bear was killed in the early 1920’s. But in 1953, the Grizzly bear was voted in to be the official state animal. In 1931, the valley quail was the named California state bird and is known for its ability to adapt fast. The valley quail has a white stripe under its beak, a black bib, and a black plum on its head.This fat bird is smaller than a pigeon. There are different names for the valley quail, and they are California
For years people have been taught to not be afraid of vultures. Although it is true that one or three vultures can't harm you. It's a different story when it's a committee of vultures vs. your neighborhood. But don't worry, when a committee roosts in your neighborhood and destroys it, you can use some proven solutions to stop them.
A peregrine falcon is a medium-sized bird about the size of a crow. Female peregrines are
Any species which fall into the categories vulnerable, endangered, or critically endangered are considered to be at risk of extinction. Robert Redford said “I think the environment should be put in the category of our national security defense of our resource’s because it’s just as important as defense abroad otherwise what is there to defend?” People should all take the environment more seriously and protect the future for those to come. It’s our responsibility to ensure that the children to come may enjoy all of earth’s beauty, and not through old issues of National Geographic’s.
In the world today there are about five thousand endangered species. Around one specie dies out every year. Some animals become endangered because people are killing them for their horns, as in the case of the Black Rhino of Africa. Others become extinct because pesticides are put on the food we eat, causing the animals that eat the insects off the plant to become contaminated, which causes their predators to become contaminated, which often affects the shell of that organism?s egg. Here is a list of the endangered species, 91 endangered birds, 76 endangered mammals, 36 endangered reptiles, 21 endangered amphibians, 115 endangered fish, 70 endangered clams, 35 endangered snails, 44 endangered insects, 12 endangered arachnids, 21 endangered crustaceans, 594 endangered flowering plants.
In our world today we have approximately 26,021 endangered species. Endangered species are organisms that may possible become extinct. The term 'endangered species' refers to all species that fits this description. However some conservation biologists and scientists normally use the term ‘endangered species’ to refer to species that are put on the IUCN(International Union for Conservation of Nature)Red List. Many factors can be looked at when considering the conservation status of a species. Factors such as human threats or environmental threats can cause a species to become endangered.
