Peafowl

Marion Petrie began her controlled breeding experiment with peacock offspring by observing peahen mate preferences in Whipsnade Park, UK. Observations showed that peahens appeared to have a preference for peacocks with more elaborate trains (i.e. larger in size and more eyespots). Petrie was interested in finding out why the peahens were mostly attracted to the peacocks with the most elaborate trains in this population. To test this idea, Petrie took eight males of different attractiveness from Whipsnade Park and separated them into individual pens. She then placed four females in each peacock’s hen at random – there were 32 peahens total used in this experiment. Petrie’s hope was that the peahens would mate with the peacock so that she could observe their offspring and keep track of their growth as it was affected by paternal genetics. On day 84 of the observation, the size of the offspring was measured to see the effect the males’ genes on the offspring’s growth. From the data that Petrie collected, she found that there were differences in the growth among the fathers, the sons, and daughters. Taking into account this detail from the data, Petrie conducted a multiple regression analysis, and found that the tarsus length, the train length, and the size of the eye spots on the father’s train affected the size of the offspring. These variables along with the hatch date and egg weight – which are an important factor in this experiment because if the eggs hatch early, they are…

Peafowl are exotic, beautiful birds. Most people are not educated about peafowl; most people don’t even know what the word peafowl means. Peafowl is the general term when talking about the peacock, peahen, or peachick. The peacock is the male, the peahen is the female, and peachick is the baby. People that do not raise peafowl nor educated in peafowl know what it takes to produce high quality feathers or chicks, that there is more than one variety of peafowl, nor do they know peacocks molt.…

The Strengths in the Original Poem of “Intimacy” By removing “Peacock feather,” the delicacy of the feather is diminished. A wheelbarrow is a rough object. The wheelbarrow does not offer the same imagery with the line of “wide eye tamed with dirt” as the “peacock feather does”. A wheelbarrow is neither wild nor tamed, but a peacock is a free animal, and one that is not typically domesticated or tamed. The father also references to the title: “Intimacy” of being a soft and fragile concept. The…

more creative than someone who can't relate to the subject. In one study, subjects that are put in a "mating mindset" express increased creativity compared to those that are shown a picture of a street. The suggestive nature of the woman's picture ignited a creativity that the street did not. This creativity was predominantly shown by the men who participated in the study. Why do men who have strong sexual motive depict a more creative mindset when it comes to writing? Ultimately, it came down…

hypothesis: male and female humans are virtually indistinguishable when it comes to behavior and intellectual prowess. She then proceeds to use examples from different species to disprove this hypothesis, saying female elephants are more social and verbose than their male counterparts and male zebra finches are more talented at singing than females. She then tells the reader, perhaps most shockingly, about the green spoon worm. This creature, found at the bottom of the ocean, has such…

sexual reproduction taking genetic information from two individuals to make one individual for the next generation. The ideal mates become those that a population identify as possessing the characteristics most likely to survive and carry on their bloodline, this includes the ability to reproduce. This is sexual selection and it plays an important role in the continued evolution of a species. Intersexual selection is a result of an individual of one sex choosing the other as a mate because…

myths, folklore, religion, arts and culture. The oldest visual image of the human fascination, love and reverence for nature in India can be found in the 10,000 years old cave paintings at Bhimbetka in Central India depicting birds, animals and human beings living in harmony. The Indus Valley civilization provides evidence of human interest in wildlife, as seen in depicting images of rhino, elephant, bull, etc. The earliest concern for the wild life law could be traced to 3rd century B.C. when…

It is beneficial that the researchers realized especially students with their laptops can verbatim type more than others who prefer long-hand. However, the others as use long-hand, they always be more successful from the typing learners.Therefore, nowadays although how much we feel that, while we are improving in some technological field, there is also another inevitable truth of further disconnection from the natural world, from our senses and actually from our own being. As it seems,…

of high rate of killing of young ones on the one hand and delay in conception on the other (Balme and Hunter, 2004). 2.5.1.2. Feeding behaviour Leopard in different habitats prey on different species of animal available there. Leopards kill prey like impala (Aepyceros melampus), hyrax, civet and mongoose in Kruger National Park in South Africa (Bailey, 1993), whereas in the Kalahari desert they prey on Bat-eared foxes (Otocyon megalotis), jackals (Canis spp), genets (Genetta spp), hares (Lepus …

Singing the virtues of Dharma(duty), the Gita, one of the most priced scriptures in Indian Mythology, is the advice given by Shri Krishna to the grief laden Arjun, who is terrified at the thought of killing his kin, on the battle ground. Mahatma Gandhi revived these virtues again, breathing new life in them, during India’s freedom struggle against British Colonialism. An ardent believer in communal harmony, he dreamt of a land where all religions would be the threads to form a rich social…
