Barred owls are large, stocky owls with rounded heads, no ears tuffs, and medium length rounded tails. Barred owls live in large, mature forests near water. Spotted owls are dark-brown, large owls with rounded heads, the wings are broad and rounded, and the tail is short. Spotted owls also live in mature, large forests but, are sensitive to habitat disturbance. Now, Barred owls and Spotted owls are in a intense war for homes. Originally barred owls originally lived on the east coast but recently they have been invading the home of the spotted owls living on the west coast. While they are invading they are pushing out the native spotted owls. Northern spotted owl population have fallen by about 12 percent each year. (Washington Post). In addition

To determine the migratory patterns and population patterns of the Barn Swallow, I examined different charts provided by the BPP website that allow me to examine the population numbers of Barn Swallows in different parts of North America during their mating seasons. According to the information provided by the BPP website, Barn Swallows have a tendency to live closer to areas that have a higher amount of water. This means that they nest in areas where the climate is more damp. Barn Swallows make their nests out of mud and twigs which makes it necessary for them to live in areas where the environment has more rain or is damper so that they can use the mud to create their nests. The information provided by the BPP clearly shows this due to the fact that throughout the years, larger populations of Barn Swallows are shown to be along the eastern coast and the Great
The Northern Spotted Owl is one of the three subspecies, a division of a species, of spotted owls. A medium-sized, chocolate brown owl with dark eyes, the northern spotted owl is a nocturnal "perch-and-pounce" predator that captures its prey (primarily small forest mammals) with its claws.

The barn owl is the most widely distributed species of owl, and one of the most widespread of all birds. Barn owls are birds of prey. These birds eat mostly rats, mice, voles, lemmings, and other rodents; also shrews, bats, and rabbits. Barn owls are the most widespread of all owl species. They are found in Europe, Africa, India, southeast Asia, Australia, North America, Central America, and North America.
They are losing grasslands and woodlands to hunt for prey and dense, suitable trees to nest and roost. Habitat loss is caused by land development, forest thinning, and conversion of softwood forests to hardwood forests. Another decrease in population is because of predation, or the preying of one animal on another. After increases in grasslands in Iowa no population increases were reported. Long-eared Owls nest in the dense part of trees or in abandoned nests of crows or magpies so often, people destroy their nests without knowing. The last reason for decrease in population is the conservation groups often overlook Long-eared Owls. Iowa is increasing their grasslands and woodlands to help the Long-eared Owl get off of the threatened list. Also, people are setting weaved baskets for the Long-eared Owls to nest and roost.
Soaring high above the ground late at night, under the dark canopy of trees. Stooping down low to catch a small rodent. It flies back up into its nest, ready to eat. There is only one animal that matches all of these descriptions, and that’s an owl! A particular owl, called the Northern Spotted Owl, is a small brown bird that lives in old-growth forests also known as “cloud forests”. This essay will provide information on the northern spotted owl and discuss its appearance, habitat and diet, and give you some interesting facts about it.
In terms of the specific concerns you have raised, first, we will find a shelter for these animals to grow and thrive. Shortly after, we will clear out the owls and their young from the construction site. It would bring us great joy to allow you to come onto the site and look for any other owls that may have been left behind. We will immediately move the owls into a shelter that we have chose. Finally, while the owls are settling into their new home, construction will continue.
Have you ever wondered what a Northern Spotted Owl is? Well then you will want to read this. This will hold information about a Northern Spotted Owls appearance, habitat and diet, and give you some interesting facts about them.
Fortunately, barn owls are able to fly away silently and undetected by their
Snowy owls tend to be like other owls in that they are monogamous and mate for life. They are fiercely protective of their nests and breeding area. They will go so far as to attack wolves if they believe them to be a threat (“Snowy Owl”, 2012). This extreme protection does not just stop with their own nest. They create an unintentional benefit to dark-bellied brent geese who nest close to snowy owls for the protection of their own nests. The closer these geese place their nests to the snowy owl’s nest the safer they are as well as if their nest is far from the snowy owl nest there is more danger and thus a higher chance of nest abandonment. The more protection these geese have the larger the number and size of their eggs as well (van Kleef, Willems, Volkov, Smeets, Nowak, & Nowak, 2007).
Many different species of animals are threatened by harmful chemicals and pollution that hinder said species literal existence. DDT, PCBs, organophosphate pesticides, and mercury, for instance, sneak into many different predators, including the barn owl. The barn owl preys on specific species of animals; however, the barn owl is not embedded with the chemicals themselves. Chemicals like DDT, PCBs, etc. are within creatures called mice, moles, shrews, and voles; therefore, the owls retrieve these deadly chemicals when they prey on these specific animals. Ecologists fear for the barn owls existence because of the insecticidal chemicals and their impact on the bird.
The California Spotted Owl (Strix occidentalis occidentalis) is a subspecies of the Spotted Owl. They are found in northwestern California, western Oregon, western Washington, and southwestern British Columbia. They live in old growth forests around 200 years old, preferring Douglas-fir and high canopy areas. They are described as medium sized, brown owls with white spots. The California Spotted Owl has a height of about 1.5 feet and a wing span of around 4 feet. The California Spotted Owl is a nocturnal bird whose diet consists of rodents, reptiles, invertebrates and birds. The lifespan of the California Spotted Owl is around ten years. They mate for life and require a vast amount of territory (National Wildlife Federation, 2015).
Great Horned Owls generally use nests built by other species. They usually lay two eggs per season, but can lay anywhere from 1 to 5. It takes between 30-37 days for the eggs to hatch.

Bald eagles live only in the United States and Mexico. Bald eagles will only live near lakes and rivers. A bald eagle's nest is about 70 feet above the ground in tall pines or deciduous trees. Nests are almost 7 feet wide and five feet deep. The territory of a Bald Eagle has a carrying capacity of 10 to 40 square miles, per eagle.
