The Common Starling, otherwise known as Sturnus Vulgaris or European Starling, is a medium sized songbird that is a member of the Sturnidae bird family. These birds are known to mimic sounds from other species and can even mimic human speech when held in captivity. They are very stout in their build and have short tails. They change color depending on the season, such as purple-green feathers in the summer and brown feathers with white spots in the winter. Common Starlings originated in Europe, specifically Norway, Russia, and Siberia. During the winter, they migrated to northern Africa and India. From there, Starlings have been introduced to several places such as Australia, New Zealand, Tasmania, South Africa, and North America. They are normally found in grasslands, agricultural areas, and urban settings. There have been a couple attempts to introduce Starlings to North America but both times resulted in failure. However, in 1890, the third attempt permanently established the species in Central Park, New York City by Eugene Schieffelin of the American Acclimatization Society. ...
In Cold Mountain and "A Poem for the Blue Heron", tone is established in a multitude of ways. These two pieces of literature describe the characteristics and actions of a blue heron, both aiming for the same goal. However, Charles Frazier and Mary Oliver approach their slightly differing tones employing organization, metaphoric language, and diction.
Many people think that Christopher Columbus was the first European to set foot in America, but this conventional belief is wrong; Leif Erikson, a Norse explorer set foot in Newfoundland almost 500 years before Columbus was even born. This paper will cover everything about Leif Erikson’s life including his grandfather’s banishment from Norway, and Leif’s father’s exile from Iceland. Leif Erikson’s early life, his family, and his visit to Norway to serve under the king. The first recorded European to see North America, Bjarni Herjólfsson, and Leif Erikson’s voyage to America. This paper is also going to talk about Leif Erikson’s brother, Thorvald Erikson’s voyage to Vinland because his tale is interesting. Near the end of this research paper, it will have a paragraph on Leif Erikson’s later life. Finally at the end of this paper it is going to talk about the unknown reason why no other Europeans sailed to Vinland, and Leif’s impact on modern day North America.
The purpose of conducting this experiment is to find out how an invasive specie affects different native animals. In the past, invasive species have spread disease, created more competition, and had grown exponentially to then destroyed land. By comparing populations between native birds and an invasive specie, in this case the Eurasian Collared Dove, we can find out how the native birds were affected. We are examining how the Eurasian Collared dove affected populations of native birds in San Diego. Further research would allow us to view the reasoning behind what occurred to the native species. We are choosing the view effects on San Diego’s native birds because the climate in San Diego is considered fair and stable year round fluctuating
The Black Capped Chickadee is not among the most majestic kinds of birds, but its over-sized head, small body, human curiosity, and musical talent make this a lovable bird. The cap of black feathers that cover the top of its head and extend down to the eyes give this bird the name Black Capped. Some of these birds’ physical features include white cheeks, gray backs, and short plump bodies. The Black Capped Chickadee is a very lightweight bird weighing only 11g and measuring 4 to 6 inches long. This bird has a 6 to 8 inch wingspan; this feature helps the bird land faster and with ease. Black Capped Chickadees have three-toed feet intelligently made for perching. These Chickadees have little feeling in their feet because they contain very few nerves and blood vessels.
Mytilus Californianus are known as California mussels that form dense mussel beds and considered one of the most abundant intertidal organisms. They are found clustered together in the upper-middle zone on the open coast. Mytilus Californianus attach themselves to rocks by byssal threads. They have geographic range from the Aleutian Islands of Alaska to northern Mexico of Baja California (Morris et al. 1980). “It provides habitat, refuge, and provides food for over 300 other species” including human (rust, 2011). For long period of time, human use these mussels as a food source. These mussels can grow up to 130 to 150mm in size but the process usually is attained in three years. Scientists
The European Starling or Sturnus vulgaris is a brownish black bird speckled with white spots. The juvenile is slightly browner, while the fully grown bird is black and more lustrous. They are native to Eurasia and North Africa. They have a stout stature, with a short tail.
Compared to the size of a teacup, the eastern gray squirrel is a small animal, with body length ranging from 25 to 30 centimeters tail lengths ranging from 22 to 25 centimeters, and weighing 400 to 600 grams. Contradictory to their name, their fur color is not gray but a combination of black, white, and brown colors. This fur coat that creates a gray illusion helps the squirrel blend into their environment.
Pitx1 is a gene with in a larger family of similar genes, referred to as homeobox genes that direct the formation of many body structures during early embryonic development. Pitx1 in particular, encodes for a protein of some 283 amino acids (varying slightly in different species) that acts as a transcription factor and is in charge of regulating the expression of other genes involved in the differentiation and function of certain developmental regions. The scientists in this study have been interested in the role of this Pitx1 protein and the differentiation and function of the development in particular of the hind limb regions in the threespin stickleback fish. Through their previously conducted studies these scientists concluded that the
SPECIES- Ursus Maritimus, Polar Bear, lord of the Arctic. Lives in an area of five million square miles of snow and ice. From Siberia to Alaska and across Canada, Greenland and the Islands north of Norway, he is the master of all living things except man. It lives in the brutal cold, ice, and snow.
the interior least tern is endangered due to destruction, alteration, and curtailment of nesting habitat. The least tern bird was put on the endangered list May 28, 1985 and has since been on the endangered list. The cause of Channelization, irrigation, and the construction in many reservoirs and pools have been a major cause to the elimination of much of the tern’s sandbar nesting habitat in the Arkansas and Red River systems. The birds can be found inhabiting in sandbars of the Arkansas, Mississippi, and Red Rivers during the summer months while they nest and raise their young. Least terns also nest on artificial habitats such as sand and gravel pits, dredge inlands, dike fields along the Mississippi River, ash disposal areas of power
It is a large and beautiful blackish-blue in color bird. They have a crest that is white and short. The feathers on their back and tail are a silvery-white. They have wattles that are red.
Blue jays aren't the only jays out there. For example, the Stellers jay has less white in his wings. His head and chest are black with darker under parts. A Scrub-jay's crest and wings are solid blue, and its tail is white, black and barring.
*All wild birds learn to mimic their parents and adults of their species early in life. Some can even mimic the sounds of other wild birds. *Most known for this behavior are myna birds, the Australian Lyrebird, and the mockingbird. *A bird's ability to understand or speak another bird's language can be very valuable in the wild. But what about those birds who learn to mimic human
Hello, I'll be talking about the constellation of fish as fish- this is my zodiac sign. Constellation Pisces consists of faint stars, the brightest of which is a fish the Arabic name Al Risha, which means "rope", it is in the place where knotted ribbon extending from the northern and southern fish. Find the star can be a bit random on the continuation of the underside of the Great Square of Pegasus star a and g. From Al Risha depart two lines of faint stars - one on the north to the Andromeda b, and the other is to the west; the first ends at the "north" fish that is ready to bite the Andromeda, and the second in the southern fish, which lies on the back of the winged horse Pegasus.
As colonial communities developed and overtook their indigenous counterparts, the dependency on the natives to participate in wolf predation and subsequent game management dwindled to a point where communities felt they could handle the predators internally. The problem and early solution, as described by Jon Coleman, fell in the field of local legislation: “Town councils across New England passed laws aimed at taming unruly beasts, but free-ranging livestock was a fact of life.” Early Americans were able to adapt folklore and stories about the dangers of wolves quite easily due to their shared sources of nutrition and the predator’s ability to capitalize on the slower and more vulnerable animal property. This integration of legend and property
