Bridget Stutchbury is a biologist and ornithologist, who was born in Montreal, Canada, in 1962, but was brought up in Toronto, Canada. She received her M.Sc. from Queen’s University and her Ph.D. from Yale. She was also a postdoctoral fellow, a person doing research after receiving their doctorate degree, and a research associate at the Smithsonian Institution. Bridget became interested in songbirds in the 1980s. She studies the migrations of the tiniest birds and the threats posed upon them. (Cameron, 2013) Stutchbury had many questions such as: why do certain birds mate five or ten times an hour, how are mates chosen and how do they care for their offspring, and many more. She followed these songbirds to Latin America, their wintering grounds, and North America, …show more content…
The probability of nest survival didn’t change treatments, but density was usually higher in logged sites than reference sites. In recently logged sites, brown-headed cowbird parasitism was higher and reference sites produced more Hooded Warbler young per successful nest than standard selection harvest sites. Fledgling survival wasn’t negatively impacted by logging treatment. Overall, more than 50% of fledglings survived up to three weeks after sites had the highest Hooded Warbler density, they also had the lowest seasonal productivity, which raises the possibility of an ecological trap. The number of daughters produced top female per year that are expected to survive to their breeding age was lower in all treatments than the expected annual mortality of adult females. Regardless of the extent of partial harvest within the fragments, forest cut downs appear to be population sinks. (Eng, Stutchbury, Burke, Elliot,
Bridget Mason went from being a slave, owned by quite a few slave owners to the wealthiest African American woman in the early 1800’s. She became a very successful nurse in Los Angeles, California. Mason was well known for being a helpful woman to others, others in need of help. Others who were slaves needing help to establish in an area where slavery was not legal.
“Passenger Pigeon”, written by John James Audubon, is the author’s account of the now extinct pigeon at a time the bird soared across North America in great numbers. The work itself is an entry of a larger scientific work describing various birds and their traits, but Audubon’s exposition varied from the scientific documents his peers were writing. The work begins with a rich description of the passenger pigeon, but soon Audubon begins to discuss a personal story involving the bird. The cycle continues throughout the work, as Audubon goes from factual information to his individual encounters with the bird. Audubon’s story is summarized through his scientific descriptions of the pigeons and his stories of encounters with the passenger
Species for which the model in Dwyer et al. (2014) performed well are widespread and occupy many habitats in California, but those that performed poorly are at least seasonally tied to specific habitats or geographies. For example, all three species occupy areas with topographic variation. Golden Eagles and Turkey Vultures are obligate cliff nesters, while Common Raven is a facultative cliff nester that also nests in trees and sometimes on powerline poles and transmission towers (Thelander 1974, Grinnell and Miller 1944). In flat areas, power line poles may extend the usefulness of associated habitats to these species by offering elevation over surrounding terrain, a wide field of view, and a point for easy take off (Benson, 1981; Stahlecker,
This book is set against the backdrop of middle school; the primary focus of which is three girls who are best friends. The main character, Bridget, lives with her musician mother and coffee shop owner father in New York City. The story actually begins several years earlier, when Bridget miraculously survives being struck by a car as she skates through an intersection. The incident affected her significantly, as she then begins to view herself differently and wonders if there was a special reason why she survived.
The secretive marsh birds that the article refers to are almost impossible to find without high tech portable tools and even then that only works during the mating season of these birds were they are the most vocal. However, even those these birds are typically neither heard nor seen by humans they interact with their environment acting as the consumers of the dense vegetation that is plentiful in the wetland environment. They also act as the prey for their predators becoming a food source for these animals that without these birds would have a more limited source of food during the fall and spring seasons. Due to the fact that these birds do have an impact on the wetlands of Missouri it is important that we promote conservation efforts within these ecosystems in order to ensure that all of the species that live in and utilize the wetland have the resources they need to survive in the future. These conservation efforts can help promote the health of the ecosystem as a whole and ensure that the environment continues to possess the dense vegetation it needs in order to support the secretive wetland birds. This may help prevent these birds from being unable to find a satisfactory habitat in Missouri to support their current migratory patterns allowing them to remain a part of Missouri’s Wetland
After observing the westfield river and the wetland land area for birds as a group, we discovered a higher amount at the river. There was 21 birds spotted at the Westfield river and 19 at the wetland area. This proves part of our hypothesis correct. We believed from the beginning that this would be case because the wetland area acts as nesting zone for the birds. The dense vegetation at the wetland makes it easy for small bird species to to hide their nests from predators and for good shelter. Yet, birds don’t spend the majority of their time at the nests, they are spent scavenging for food which is better found in the floodplains of the Westfield river.
McCaffrey, 2005). Therefore, as an additional component of this project, the Park Monitoring Program was established. The data provided by this program was biased because it allowed the scientist to observe any point of interest on a quarterly basis. In conjunction, experience picked up from planning the TBC program, selecting volunteers, making the information accessible to people in general and analysts, and standing up to the difficulties connected with such a study, can serve as a case for different specialists inspired by setting up resident science–based ventures/projects in urban territories. In conclusion, this project has sanctioned a more detailed information of the Tuscon-area bird species, which was more than a whooping of 200 bird species. The TBC exhibits the benefit of using subject researchers to gather citywide information for checking urban flying creatures. In the present, the TBC is the main repeating volunteer-based, citywide urban winged creature observing venture on the planet (Rachel E. McCaffrey,
“Focusing isn’t just an optical activity, it is also a mental one.” -Bridget Riley. Bridget Riley was born on April 24, 1931 in West Norwood. The daughter of a businessman, John Fisher Riley. She spent her childhood in Cornwall and attended Goldsmiths College and the Royal College of Art. She began painting figure subjects in a semi-impressionist manner, then later changed to pointillism around 1958 but mainly producing landscapes.
Prior to 2008, the only known inhabitants of the St. John’s College garden had been the songbirds and squirrels that darted across the neatly cropped lawn and hid in an ancient beech tree. Generations of dons and students had strolled

It is clearly stated in the Surface Mining Control and Reclamation Act of 1977 (SMCRA) that surface mining operations cause environmental and social damage “by impairing natural beauty, by damaging the property of citizens, by creating hazards dangerous to life and property by degrading the quality of life in local communities...” (#6). Surface mining causes more damage to the environment than other methods. Everything ranging from air and water pollution to degrading land and loss of biodiversity has been caused by surface mining. The Appalachian mountain region is the most diverse forest in the world. There are a large number of salamanders and migratory birds, along with waterways, the first link in the food chain that supports the entire forest. Valley fills, where overburden from surface mining is dumped, can cover up streams, thus breaking the food chain. In an Environmental Protection Agency (EPA) study, it was found that a large number of mayflies have disappeared. This may seem like a small loss, but it will affect other creatures in the future. As more and more chains break in the food chain, the less diverse the forest is. It was also found that the cerulean warblers, a migratory bird, has been decreasing in population. In fact, over 40 years, the cerulean warbler has decreased by 82% (McQuaid). These small creatures are vital to the diverse ecosystem of the Appalachian mountains.
On a nice spring day the buzzing sound of a hummingbird flying can often be heard, and people look out the window for a chance to see the intriguing little bird. There are over three hundred and fifty species of hummingbirds some as far south as Chile and others as far north as Alaska. Hummingbirds are beautiful creatures that range five cm. to twenty cm. tall. The remarkable birds are the only type of birds who can fly backwards and are characterized by their long beaks. With so many different types of these fascinating birds most people don’t stop to think they could be in danger. Hummingbirds are an endangered species because of the causes of they’re endangerment, what they need to survive, and the effects of their endangerment on humanity.
Bird use fine-tuned homing and migration techniques for a variety of different reasons. Migration and homing will most often conjure ideas of birds that migrate thousands of miles on a seasonal basis from their breeding grounds to their wintering areas. Almost half, over four thousand of the world’s ten thousand species of birds migrate on a regular basis. They do this to find suitable habitat for breeding and wintering. The godwit bird will travel from Alaska to Australia flying day and night over the Pacific Ocean (Heinrich 70), raptors will travel thousands of miles during the day over land along well-established corridors (Bildstein 2) while thrushes travel at night over land, typically taking off after sunset (Chu 53) . Homing also plays a very real role in everyday living. Birds also use their homing instinct on a daily basis because of their constant coming and going from their nest. Albatross will travel hundreds of miles crisscrossing the ocean in search of a meal to bring back to their nest and once finding it will fly straight back home (Heinrich xi) and Shearwaters will never cross land spending all their time over water gathering food (67). Compared to other areas of research about bird’s lives most about how birds migrate is unknown. There are over a million birds a year that are banded in just America to try to understand how and where different species travel (Heinrich 67). What is understood is that
On an average given day in early spring, a beautiful Monarch butterfly floated on the air hundreds of feet above the valley. This butterfly considered herself quite lucky because she just happened to be made of her favorite colors. Her wings were a deep, rich orange outlined in black with white dots scattered around the edges. From her perspective, she could see both the south and north woods in their entirety. She could see the whole lake and noticed a young cougar, the cub from the previous summer, now fully grown. He was napping in the warmth of the sun on the same large boulder that Fox found to be so useful. He seemed content and at peace. Below her was Willows pond. She floated down as gently as a feather and landed in the grass on the west edge of the pond.
Translocation of native birds to offshore islands has been a part of ecological restoration in New Zealand and has started since 1890’s. This translocation to mainland islands was started by the Department of Conservation in the year 1995. Wenderholm Regional Park has an area of 60 hectares maintained for ecological restoration. The area has been fenced to prevent the entry of livestock and the pasture land is reforested. The ecology of the park was restored to the status of enabling bird release into the park by reducing the number of predators. North Island robins were introduced into the park in 1999. The productivity rate of the robins was very high. But the dispersal rate has also been high as the young fledged away to nearby habitats. As the park is linked to adjacent forest areas, it makes it easy for bird dispersal into surrounding areas. The result of such translocations is not sure and hence further translocations must consider various factors before any bird introductions.
