      In keeping with our focus on Appalachian culture grades K-3 will be looking at the owl, a typical bird of prey found in the Appalachian mountains.  We will also be studying about the naturalist and ornithologist John James Audubon who drew the birds that were indigenous to Ky. and the area along the Mississippi River.



 John James Audubon (Jean-Jacques Audubon) (April 26, 1785 – January 27, 1851) was a French-American ornithologist, naturalist, and painter. He was notable for his expansive studies to document all types of American birds and for his detailed illustrations that depicted the birds in their natural habitats. His major work, a color-plate book entitled The Birds of America (1827–1839), is considered one of the finest ornithological works ever completed. Audubon identified 25 new species and a number of new sub-species.


 Bedsides drawing a realistic portrait of an owl the students will be learning the following facts about these magnificent birds of prey.  Owls are a group of birds known for their distinct calls, nocturnal habits and silent flight. Owls are familiar to many people because they are often depicted in various ways in popular culture. They rank on par with bats and spiders as the most celebrated of Halloween creatures. Owls also appear as wise and noble characters in many children's stories, including Winnie the Pooh, Mrs. Frisby and the Rats of NIMH and Harry Potter.
Here we'll go beyond the myths and the stories of owls to explore ten facts about real-world owls:
FACT: There are about 205 species of owls.
Owls belong to a group of birds that includes about 205 species. These species are sorted into two basic groups, the barn owls and the true owls.
FACT: Owls are predators.
Owls feed on a wide variety of prey. Their main food source consists of small mammals such as mice, squirrels, voles and rabbits. They also supplement their diet by feeding on birds, insects and reptiles. Owls cannot chew their prey since, like all birds, they do not have teeth. Instead, they swallow small prey whole. They must tear larger prey into small pieces before swallowing. They later regurgitate pellets of indigestible material such as bone, fur and feathers.
FACT: Most owls are nocturnal.
Most owls hunt at night and in doing so avoid competition with daytime avian hunters such as hawks and eagles. Although nocturnal feeding is the norm for most owls, some species such as burrowing owls and short-eared owls feed during the day. Still other species, such as pygmy owls, feed at dusk or dawn.
FACT: Owls' eyes are fixed in their sockets.
Owls are unable to move their eyes within their sockets to a great extent, which means they must turn their entire head to see in a different direction. Because owls have forward-facing eyes, they have well-developed binocular vision.
FACT: Many species of owls have special flight feathers adapted for silent flight.
Owls have developed special feather adaptations that enable them to minimize the sound made when flapping their wings. For instance, the leading edges of their primary feathers have a stiff fringes that reduces noise while the trailing edge of their primaries have soft fringes that helps to reduce turbulence. Downy feathers cover the surfaces of the wing to further reduce sound.
FACT: Owls have long been a part of human folklore and legend.
Owls are depicted in cave paintings in France that date back 15,000 to 20,000 years. Owls also appear in Egyptian hieroglyphics. They have held a variety of symbolic roles in culture and have represented misfortune, death, prosperity, and wisdom.
FACT: The tufts of feathers atop some owl's heads, referred to as 'ear tufts' are for display only.
Owls' ears are located on the facial disc behind the eyes and are concealed by feathers. Owls have an acute sense of hearing that helps them locate and capture prey. In some species, the ears are located asymmetrically on either side of the facial disc to enhance their ability to pinpoint the origin of the sounds they hear by sensing the minute difference in the time that sound reaches each ear.
FACT: Owls have strong feet like raptors, with two forward-facing toes and two backward-facing toes.
FACT: Owls have a long, hooked bill.
In many species, the bill is partly concealed by feathers so it appears smaller than it actually is. Owls use their sharp bill to tear their food.
FACT: Owls do more than just hoot—they create many different vocalizations.
Owls create a wide variety of sounds or vocalizations. The familiar hoot is usually a territorial declaration, though not all species are able to hoot. Other sounds owls might make include screeches, hisses, and screams. Owl vocalizations are loud and low-pitched. Their cries travel well through the night air, enabling them to locate mates and declare territories despite the darkness.
