Beak

An ostrich’s beak was made for eating herbivorous things, such as plants or small animals that eat mainly plants even though an ostrich will eat almost anything he can get his talons on. An ostrich eats many plants in his preferred diet, but on occasion will also eat mice, lizards, and insects, even though his talons and mouth aren’t made to consume those types of food. Owl’s use their beak to kill, and use the assistance of their claws to tear food…

anatomy, their beaks. A decurved bill such as the one present in Numenius arquata has numerous advantages over a straight bill for such foraging on mudflats. Foraging Curlews use probing as a way to take their prey from the soil surface. Nebel, Jackson, & Elner (2005) define probing as a foraging technique that consists in inserting the bill into the sediment, allowing the capture of invertebrates that live below the surface (infaunal prey). Based on that, a bird with a decurved beak will be…

Charles Darwin was a scientist. He lived from 1809 to 1882. He observed variation happening in nature. He hypothesised the Theory of Evolution, which was how life had changed over time. This could also be known as how modern species have developed from ancient organisms. Darwin observed that organisms normally produce more offspring than can survive. Also not all offspring are identical. There is variation (differences) in their physical traits. Lastly, different organisms must compete to…

At the end of the lab, there were several different Chromaseratops offspring. It is like that because of meiosis. That process creates the cells and gives them chromosomes which become homologous pairs. From there, you can make a lot of different combinations of gametes. For this lab, there was 8 different gametes since there was 3 homologous pairs. For a human there would be way more combinations since we have 23 pairs or 46 chromosomes. Through independent assortment, you receive 2 homologous…

Australia. Physical description-A large 'goose sized' bird. It has a long black neck, ending in a wave of white. A slice of white shines from its black tail feathers, and the top of it's wings, back and front, are also white. It has a sharp, orange beak. Lifestyle-These birds live in large groups, mostly consisting of over 100 of them. Habitat-These birds live in floodplains and wet grasslands. This probably means their diet consists of fish. Food-Since the Magpie Goose lives in floodplains…

The Venetian Masks are an old traditional mask of the city Venice in Italy. These types of masks were usually worn during carnivals and other times they were used to hide someone’s identity or social status. They let people be free and interact with people out of their normal social world. Some other purposes they were used for were for criminal purposes and others used them for a romantic encounter but sometimes the reasons were unknown. These masks have a unique design that contains ornate…

magnirostris. Character displacement in finches can describe the evolutionary divergence from traits needed in in organism life cycle. As proposed by Lack in the Grant and Grant paper, character displacement caused G. fortis to evolutionary develop smaller beak sizes in order to consume smaller seeds. As smaller seeds were prevalent, finches would consume those as a food source. Once diminished, large seeds were the seed of choice for them. Unfortunately, they were not able to adapt their small…

Evolution is an idea that has been toyed with by many other scientists for centuries, but is generally considered to be the “unifying theme” and the “binding force of all biological research” (Evolution: Theory and Science). Georges Cuvier and Jean-Baptiste Lemarck both had theories that kind of headed towards evolution, but they simply had pieces of the whole picture. The writings and theories of these two naturalists and others are what inspired Darwin on his travels. All this along with his…

Everglades it eats many crayfish. The white bird has a curved, long beak that helps it get through the mud to find fish. Ancient Egyptians thought that the bird was going to be the reincarnation of Thorth, their God. Wood stork is a larger bird than Ibis. The bird eats in an unusual way. It shuffles it feet and puts it’s head in the water. When the fish swim away from the feet of the bird they run into it’s beak, and the bird’s sensitive beak grabs the fish in about a fraction of a second!…

fluffy bird. This type of bird has a light blue and black color on its throat and also a little bit above the throat. The belly of the bird has a light grey and brown color on it and the beak is a very dark black. On the other hand the female malurus had a brownish color for it’s soft fur and a orange gaping beak. The shape of the malurus is a oval , round shape. The typical weight for the male is 8 through 13 grams but , the weight of the exact weight of the female is unknown what it is known…
