Magnetic sensing is a type of sensory perception that is present in many living organisms, allowing them to perceive magnetic fields and to use the information from earth’s magnetic field in orientation behavior.1 This can be found in many animals like migratory birds, sea turtles, honeybees and even bacteria. Migratory birds use magnetic clues to find their way south in fall and north in spring.2 The navigation ability of birds has been studied mainly in migratory birds and pigeons. Scientist attached
guide, along with its taxonomy, ecology, and anatomy. taxonomy The Phorusrhacidae is a large flightless bird that existed until 2 million years ago. It used its hooked beak for smashing the prey’s body on the ground repeatedly and tearing its flesh from the body. Thus, it is a carnivorous terror bird. Most phorusrhacids can run at very fast speeds of about 45 km per hour (“Terror birds,” n.d.). It is the ancestor of today’s eagle, seriema (Degrange, et al., 2010) and the hippogriff. Since their
Puffins breed and nest in big colonies. Both the male and female take turns digging tunnels for nesting. The birds dig out holes on the hill side and sometimes fill the tunnel with nesting material. Digging nest is one way that puffins bond, the other is a practice called billing. Billing is when a male a female approach each other moving there heads side to side and rattling their beaks together. This is a very important element in puffin’s courtship. Puffin usually lay their eggs in April. Female
needed for metabolism, digestion and other important processes without protein. Protein is also important for development and growth in children, teens, and pregnant women. Natural proteins are proteins purified from natural sources. There are three types of protein and it can be classified as: Natural Proteins: On hydrolysis they yield only the amino acids and occasional small carbohydrate compounds. Examples are: albumins, globulins, glutelins, albuminoids, histones and protamines. Conjugated Proteins:
What would it mean to you to have someone you love very dearly move on to the next life? A symbol is something that represents something else. In the poem “The Raven” by Edgar Allan Poe, the raven is a symbol. At the beginning of “The Raven” the narrator is reading, and it is late at night. He reads to hopefully rid his sorrow of his wife’s death. The narrator doesn’t take his wife’s death lightly and is suffering from sorrow. The raven represents Lenore, his long lost love. The narrator was sitting
Montezuma, the last Aztec Ruler, wore a huge headdress made of feathers from over 250 birds. 2. The feathers that the Aztecs used were very vibrant in color. 3. Some fans that the rulers used were intricately made with many feathers to be attached to a bamboo handle. C. The Aztecs did not approve of public nudity with Men wearing loincloths
Land areas that are isolated form their own unique plant and animal life. Before humans arose, islands like Hawaii and New Zealand had no land animals. “Each of these places had a great number of plant, insect, and bird species that were found nowhere else in the world. The most likely explanation for the existence of Australia's, New Zealand's, and Hawaii's mostly unique biotic environments is that the life forms in these areas have been evolving in isolation from
Bio-inspired inventions are relatively new inspirations to modern engineering. However, humans have been mimicking animals for thousands of years. For example, ancient humans routinely would imitate animals’ hunting patterns to find reliable sources of food. The application of animal inspired inventions today has been applied to important roles in conservation, military, and societal needs. One creative example of an invention inspired by an organism is a robotic jellyfish developed by the U.S. Navy
