Northern Harrier Research Paper

burrowing owls are rapidly declining due to death. Burrowing owls have been killed by predators,

Northern Harriers usually fly slowly and low over the ground, their wings held in a V-shape as they glide. Most males have either one mate or two mates at a time, but some have up to five mates when food is abundant. Each male courts females and advertises his territory by performing sky-dancing displays: undulating, rollercoaster-like flights up to 1,000 feet off the ground, sometimes covering more than half a mile. Although they don’t protect large territories, both males and females vigorously defend the nest itself. Nesting females usually chase away other females, and males chase other males. Females incubate eggs and brood chicks, while males provide most of the food for the females and nestlings. Nest predators include coyotes, feral

The most effective predators on earth is a barn owls and it is less risky than using other predators such as snakes or other predatory birds. In addition, Barn Owls built their nest under natural conditions breed. For example, in cracks in rock faces and holes in trees. They have adapted well to using recesses or holes in buildings, particularly in rodent-rich environments. In farming areas like palm tree with pest rodent problems, Barn Owl populations can be increased by giving suitable nest boxes, spread widely across the farmland, for occupation and use by breeding owls. Once in residence, the owls will hugely increase the levels of predation pressure on the nocturnal rodent population, as well as reduce the rodent pest in the area by killing

The world has experienced many mass extinctions within its lifetime. More and more are occuring today with the help of homo sapiens. Everyone in the modern age has heard of the most recent extinction of the white rhino, that was hunted for their prized horns. However, not many have heard of the passenger pigeons’ claim to fame. There was an overabundance of them in the United States, particularly in eastern North America. Passenger pigeons had been in America before the Europeans dropped by and the United States was not even an idea yet. Following the colonization of America was the deconstruction of the passenger pigeon’s habitat and then eventually pigeons attacking the crops belonging to the farmers for provisions. They would fly in gargantuan flocks that

Prairie dogs inhabit among the Great Plains and grasslands in North America. They live underground in an extensive network of burrows that they build. Their burrows allow them to nurse their young and keep an eye out for certain predators that might be near by. Prairie dogs interact with other species in the area by allowing some species, such as snakes, owls, and ferrets to use their underground tunnels. This leads into the necessity of prairie dogs in their ecosystem. Prairie dogs’ tunnels provide habitats for many different species in the grasslands. They are also a food source for several different predators such as ferrets, coyotes, eagles, and badgers. The prairie dogs’ burrowing of the network of holes and tunnels also churns up the earth, allowing the soil to better support and sustain plant life. If the prairie dogs were to disappear or become extinct, then the food source of many animals would be lost, species that use their tunnels as shelter would be exposed to predators, and the soil will not be able to support the different species of

Our ever-growing hunting of predators in the natural world has exceedingly taken a toll on our ecosystem. As we are destroying the population of predators, the very problematic organisms that the predators prey on are having a population boom. The population boom of these less threatened prey have now resulted in seriously threatening changes to the ecosystem. For example, Amur Leopards have a beautifully patterned fur that can sell between $500-$1000 per pelt. With these sales, hunters are constantly hunting these gorgeous big cats, and their population has dwindled down to just a little more than 60 individuals living now. These cats, are crucial to the ecology of Asia, along with its economy and culture. They perform mutualism with other

Over the past three weeks my partner and I have been studying pests in the Bay of Plenty area and , and have chosen to research the European hedgehog due to Their extensive damage to the native species in the Bay of Plenty. Our task is to find an effective solution to mitigate the deleterious effects of hedgehogs in the Bay of Plenty area and answer some questions which we think are important to lessening the threat of hedgehogs and raising awareness.

They will primarily eat seeds and plants, so they affect the amount of seeds in the area. If they were to decrease in size, the number of insects and grain would rise. Because they are prey, they must take advantage of the tall grasses to hide from predators such as raccoons, coyotes, foxes, and even other birds of prey that include some eagles and falcons.

The Charadrius nivosus, more commonly known as the Snowy Plover is a small bird that resides typically in sandy coastal beaches or by soft sanded areas by water. This species has over time had its population decimated largely due to habitat destruction. An unfortunate coincidence, the Charadrius nivosus generally lives and lays their well-blended eggs in sand dunes and beaches that are commonly trampled by humans. Conservation actions have been taken to reduce predatory factors and promote breeding that have shown some impact, but there is still much to be done to protect this species from extinction.

Our national bird is the Great Bald Eagle, as most Americans know. The Bald Eagle is similar to the Golden Eagle, which has a wingspread up to seven-and-a-half feet. The national bird is protected by law, but the Golden Eagle is not. The result is that hunters are rapidly diminishing the number of these great bird. If the Golden Eagles are not also given the protection of the law, they may become extinct in a few years.

The common snipe to a certain extent is not considered a species of concern, although its number of conservation is going downwards. This may be because it has a very large population which may lead to the declining. Due to the draining of rivers, and the agricultural use of all types of land and grasses leads to the destroying of their habitat which intern leads to the animals overfeeding the wrong areas. Humans are also impacting on the future of the birds as today they are being hunted but a scheme is being implemented to prohibit this so that hunters to not kill this common bird. (Snipe bird

Amsterdam albatross has shown a steady decline since a massive environmental threats such as the introduction of other species that have continually damaged its habit. While that problem has lessened considerably but recent issues of diseases carried by other marine birds have continued to destroy the population. Scientific research has detail that the only population of this part of the albatross family lives and breed on the island called Amsterdam Island. With all these factors taken in along with the staggering small population of about a 100, the IUCN has classified them as Critically Endangered since 1994. With the such a small population, residing on one island and spreading of various diseases the chances of its survival are at best being very slim to its extinction being inevitable.

There are over 1000 species of birds found in the United States that are federally protected [1]. Those that are endangered or threatened need and deserve our special help and steps must be taken to protect them from population declines and extinction. However, hundreds of species--not considered to be in danger-- are still protected by federal law in a way that can prevent economic growth and the expansion of renewable energy in the United States. The 1918 Migratory Bird Treaty Act (MBTA) and related legislation make it illegal (without a waiver from the USFWS) to "pursue, hunt, or take" any native migratory bird [2]. Enforcement is often impractical but can still sometimes a barrier to the development of more renewable energy sources such as wind and solar energy. It is time for congress to revisit and reform this act to keep up with the issues that our country is facing in this, the 21st century.

To begin with, in order to understand mechanisms that influence avian population changes biologists often seek to explore similar characteristics such as biological and ecological similarities that occur across entire ‘guilds’. A guild in this sense, is a grouping of species sharing a common life-history or an ecological trait such as a shared niche. There are numerous guilds that could be classified according to factors such as comparable habitat and food varieties, reproduction and clutch size, as well as migration and nesting strategies used by the species in question. The guild of ‘aerial insectivores’- consist of birds that feed exclusively on flying insects. These insects include flies, mayflies, moths, butterflies, grasshoppers, crickets, beetles and other insects Aerial insectivores in other words, are classified as a dietary guild because of their similarities in allocating food resources. The guild of aerial insectivores consist of flycatchers, nighthawks, martins, swifts, swallows, and whip-poor-wills As this research essay is constrained in its nature it is thus impractical to spotlight the entire guild of aerial insectivores. In this research essay rather, I will be focusing on one particular species of aerial insectivore: Chrodeiles minor, otherwise known as common nighthawk, a species that consists of nine subspecies that inhabit Canada (as well as the United Sates) during the breeding season from May to

Nature surrounds us everywhere no matter where we go. It is often taken for granted or not taken as seriously as it should be. Throughout the years many species have drastically evolved while others have gone completely extinct. Some species have gone extinct due to not being able to survive the changing environment. A lot of the time species have gone extinct because people do not think about nature as something that they should care about. Conservation is a big issue that is not always thought about or addressed. In this paper there are several topics that will be discussed such as what conservation status is and who assigns it to species, what critically endangered means and how the status is determined, and details regarding one critically endangered species: The Mongoose Lemur.
