Reading Comprehension/ Animals Name _________________________________ Date ____________________ OWLS An owl is a bird. There are two basic types of owls: typical owls and barn owls. Owls live in almost every country of the world. Owls are mostly nocturnal, meaning they are awake at night. Owls are predators- they hunt the food that they eat. Owls hunt for mice and other small mammals, insects, and even fish. Owls are well adapted for hunting. Their soft, fluffy feathers make their flight nearly silent. They have very good hearing, which helps them to hunt well in the darkness. The sharp hooked beaks and claws of the owl make it very easy to tear apart prey quickly, although owls also eat some prey whole. Owl eyes are unusual. Like most predators, both of the owl’s eyes face front. The owl cannot move its eyes. Owls are far-sighted, which means they can see very well far away… but they can’t see up close very well at all. Fortunately, their distant vision is what they use for hunting, and they can see far away even in low light. Owls have facial disks around their eyes, tufts of feathers in a circle around each eye. These facial disks are thought to help with the owl’s hearing. Owls can turn their heads 180 degrees. This makes it look like they might be able to turn their heads all the way around, but 180 degrees is all the owl needs to see what’s going on all around him. Perhaps because of the owl’s mysterious appearance, especially its round eyes and flexible neck, there are a lot of myths and superstitions about owls. -

PARALLEL VARIATION IN NORTH AND MIDDLE AMERICAN SCREECH-OWLS JOE T. MARSHALL, JR. My objective in this paper is to provide for the first time a delineation of species of North and Middle American Otus based on acquaintance with their biological traits in the field. Next I wish to show their racial convergence in concealing color patterns. Finally, I attempt to portray the dramatic geographic variation in those evanescent colors and patterns of fresh autumn plumage, in recently collected specimens (largely taken by myself). -

Predator and Competitor Management Plan for Monomoy National Wildlife Refuge
Appendix J /USFWS Malcolm Grant 2011 Fencing exclosure to protect shorebirds from predators Predator and Competitor Management Plan for Monomoy National Wildlife Refuge Background and Introduction Background and Introduction Throughout North America, the presence of a single mammalian predator (e.g., coyote, skunk, and raccoon) or avian predator (e.g., great horned owl, black-crowned night-heron) at a nesting site can result in adult bird mortality, decrease or prevent reproductive success of nesting birds, or cause birds to abandon a nesting site entirely (Butchko and Small 1992, Kress and Hall 2004, Hall and Kress 2008, Nisbet and Welton 1984, USDA 2011). Depredation events and competition with other species for nesting space in one year can also limit the distribution and abundance of breeding birds in following years (USDA 2011, Nisbet 1975). Predator and competitor management on Monomoy refuge is essential to promoting and protecting rare and endangered beach nesting birds at this site, and has been incorporated into annual management plans for several decades. In 2000, the Service extended the Monomoy National Wildlife Refuge Nesting Season Operating Procedure, Monitoring Protocols, and Competitor/Predator Management Plan, 1998-2000, which was expiring, with the intent to revise and update the plan as part of the CCP process. This appendix fulfills that intent. As presented in chapter 3, all proposed alternatives include an active and adaptive predator and competitor management program, but our preferred alternative is most inclusive and will provide the greatest level of protection and benefit for all species of conservation concern. The option to discontinue the management program was considered but eliminated due to the affirmative responsibility the Service has to protect federally listed threatened and endangered species and migratory birds. -

Galliform Baraminology 4 Abstract This study investigates the number of galliform bird holobaramins. Criteria used to determine the members of any given holobaramin included a biblical word analysis, statistical baraminology, and hybridization. The biblical search yielded limited biosystematic information; however, since it is a necessary and useful part of baraminology research it is both included and discussed. -

Eastern Screech-Owl (Otus Asio)
Wild Things in Your Woodlands Eastern Screech-Owl (Otus asio) The Eastern Screech-Owl is a small, nocturnal, predatory bird, about 8.5 inches in size. The robin-sized owl has short, rounded wings, bright yellow eyes, and a rounded head with visible “ear tufts.” The ear tufts, which the bird raises when alarmed, are otherwise inconspicuous. The facial disc is lightly mottled and has a prominent dark rim along the sides. The tail and the flight feathers of the wings are barred. The eastern screech-owl occurs in two color morphs, red and gray. The red color morph is more common near the coast, and the grey color morph is more common in the interior of the state. Male and female screech owls look alike. In the fall, light and temperature conditions mimic those of spring, and birds and amphibians sometimes begin calling again, a behavior called autumnal recrudescence. At this time, the screech owl’s tremulous call can be heard in a variety of habitats including open woodlands, deciduous forests, parks, farms, riparian areas, swamps, old orchards, small woodlots, and suburban areas. This small owl is an often common, nocturnal bird in much of New York State, though it is uncommon in heavily forested regions, at high elevations, and on Long Island. The screech owl is a year-round resident, spending both the breeding and non-breeding seasons in the same area. The screech owl nests in natural hollows or cavities in trees, old woodpecker holes, nesting boxes, and occasionally crevices in the sides of buildings. Screech owl pairs may roost together in the same tree cavity during the day throughout the breeding season. -
Raptor Mews: Meet Our Birds
Raptor Mews: Meet our Birds Birds of Prey or “Raptors” are birds with hooked beaks and sharp talons that are strict carnivores: they only eat other animals in order to survive. Hashawha houses several raptor species at the Raptor Mews. These have been evaluated and deemed non-releasable by veterinarians and rehabbers. They are part of our educational programs at Bear Branch Nature Center and Outdoor School. Eastern Screech Owl Otus asio Eastern Screech Owls are the smallest species of owl found in Carroll County. Their color pattern can vary from bright red to gray. The strong patterns on the belly and back, as well as the ear tufts, allow them to blend in with their environment, making it easier to hunt for prey and hide from predators. Though they are predators, they frequently fall prey to larger owl species themselves. Barred Owl Strix varia Also known as ‘Swamp Owls’, Barred Owls can be found mainly in hardwood marsh areas. They are mostly nocturnal, and usually like to hunt at night. However, it is not uncommon to see one in the late afternoon, getting a jump on the day’s hunting. They will eat a variety of prey, including mice, frogs, and even crayfish! Barred Owls have a very distinct call. If you listen closely, it sounds like they are asking a question: “Who cooks for you, who cooks for you all?” Great Horned Owl Bubo virginianus These ‘tigers of the night’ are amazing creatures. Great Horned Owls are the top predator in the woods at night. They are extremely powerful and able to carry much larger prey in relation to their body size then other birds of prey.
