The Greek word for gymno is “naked” or “bare”, and the word for gyps means “vulture”. The California condor is a bare-headed vulture. The California condor’s species name is G. californianus. The name californianus comes from where the Condor lives, California. But the word condor is derived from the Ecuadorian Quechua word cuntur. The California condor has black feathers with a triangle of white on each wing. The adults have a bald head and on their neck they have a fluffy black ridge of feathers that look like a collar. They grow between 117 to 134 centimeters long and weigh from 17 to 24 pounds. The California condor is the largest flying bird in North America, living only in the south western United States.

The California condor or, Gymnogyps californianus, for instance, it has a hooked beak so that they can dig into the carcasses left by previous predators. Unlike its close looking cousins like the eagle or vultures, the condors don’t have a good sense of smell so they depend on their eyes to see their prey. They consume mostly large mammals on which they can eat for days. The California condor is often called "nature’s cleanup crew", because they eat all the dead carcasses left behind. Being scavengers, Condors don’t kill their food; instead they depend on other predators in the area to kill the animals so they can consume the remains. 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. They don't breed until they are between six and eight years old, and the female lays only one egg every two years. If that egg is removed, however, she will lay a second or a third. With this in mind, scientists captured wild condors for captive breeding and also began to collect eggs for captive …show more content…
They use their large wings to fly around and spot carcasses below. “There are about 435 California condors in the world today, in which 237 are living in the southwestern part of California. They live in California, Arizona, and Baja California, Mexico.” (Defenders of Wildlife, 2013) They’re as north as Big Sur to Ventura County and as east as the Sierra Nevada Mountain range, with other populations inhabiting the Grand Canyon in Arizona. Their habitat consists of forests, canyons, gorges and mountains. They make their nests high in caves, or cliff faces. California condors require large areas of remote landscape for foraging and nesting. Condors roost on large trees or openings on tall isolated rocky cliff faces. The condors need places with minimum disturbances for the hatchlings to be safe. The population almost went extinct in 1980 but now they fly freely throughout the southwestern part of the United
Grizzly bears live in a variety of environments .All of which includes dense forests, subalpine meadows, open plains and arctic tundra . In the past though, they could be found from Alaska to Mexico, and from California to Ohio. Though Nowadays there are efforts trying to make it so grizzly bears can make a comeback and the wild, and all of their efforts are proving to be working, there are 4 times as many grizzlies in the wild as there were in 1975, at

Everyone has a family member, friend, or beloved pet so sick you were not sure if they would live or die, and you find out about a new surgery procedure or medicine available to save them. Have you ever wondered where these new surgery procedures or medicines come from? When you think about all the major medical advancements over the last few decades and beyond, it has depended on animal research. As research moves into the future, we need to understand how the body works and how diseases progress. We need to find ways to treat, cure, or prevent disease and disability. The use of animal research is providing us with new technologies and medicines, which are benefiting both humans and animals in treating and extending lives.

First, the Eagle has certain traits about it that makes it such a unique and majestic bird. The bird’s Latin name is the Haliaeetus Leucocephalus which translates to “Sea Eagle with a white head” (Bald). As far as the bird goes, it has a life span of about 30 years living at the top of the food chain. An Eagle has a few weapons for hunting that make them a dangerous predator. Those weapons include the beak and talons which are both made from the substance human fingernails are made of; Keratin. The beak has a hook at the tip which is used for tearing, which creates a “scissor effect”. The talons are a powerful weapon, yet they are delicate enough to groom and feed their young. Talons are also used to kill the Eagle’s prey by penetrating its fle...
They Hyena mostly live in Africa, south of the Sahara, but except in the Congo Basin. Also large numbers of Hyenas live in Ethiopia, British Somalialand, and Ngrongoro Crater. Their habitat is usually a flat grassland. It is mostly dry and sometimes rocky area. There are few trees or plants. Mostly there are shrubs. There are also some mountains in the region.
Thousands of different types of birds roam the Earth as we know it today, so let’s begin consider the origin of these beings. How had these creatures come to be? What was their original form? The evolution of birds has only recently begun to explode with new information within the last decade (Savile, 1957, p. 212). Birds are unique creatures and inhabit a wide variety of locations, but constant among them is the fact that they came from Archaeopteryx. Over time, three key changes have developed with the bird’s anatomy that makes it a paradigm of evolution.
