Barn Owls
1. List the barn owl’s scientific name.
Tyto alba alba
2. What does the barn owl look like?
The under side is a light grey with numerous fine dark lines and scattered pale spots on the feathers. There are buff markings on wings and on the back. The underparts are white with a few black spots, occasionally none. Feathering on the lower legs may be sparse. The heart-shaped facial disc is white with a brownish edge, with brown marks at the front of the eyes, which have a black iris. Its beak is off-white and the feet are yellowish-white to brownish. Males and females are similar in size and color, females and juveniles are generally more densely spotted.
2. Describe the habitat of a barn owl: Where do they live? What kind of shelter do they need?
The barn owl is found in many different habitats but is mostly found in open woodland areas. They are normally found roosting in hollowed trees but have also been known to seek shelter in caves, wells, out-buildings and thick foliage. Their nests are typically about 20 meters high.
3. How is the barn owl especially equipped to catch its prey?
Very long legs and talons to help grasp their prey.
4. What do barn owls eat? Where do they find their food?
Barn owls typically will eat small ground mammals. The majority of this includes rodents such as gophers, mice, rats and shrews. Often these owls will perch themselves higher up where they can watch an open grassland for these rodents.
5. Describe any “special talents” of the barn owl.
Barn Owls are short-lived birds. Most die in their first year of life, with the average life expectancy being 1 to 2 years in the wild. Owl ears are located one higher than the other, increasing sound reception. During flight, the left ear captures sounds below while the right ear focuses on sounds from above.
6.Describe the life cycle of a barn owl. (including reproduction)
Barn Owls are short-lived birds. Most die in their first year of life, with the average life expectancy being 1 to 2 years in the wild. Barn owls are able to breed at any time of the year depending on the food supply. During courting, males may circle near the nest tree, giving short screeches and chattering calls. Barn Owls will lay 3 to 6 eggs at 2 day intervals. The eggs are incubated 30 to 34 days. Chicks are covered in white down and brooded for about 2 weeks, and are fledged in 50 to 55 days. After this, they will remain in the vicinity for a week or so to learn hunting skills and then rapidly disperse from the nest area. Young birds are able to breed at about 10 months.
7. What are some cool facts you learned?
Barn Owls are found on every continent, except for Antarctica. Barn Owls do not hoot, they screech.
Elf Owls
1. List the elf owl’s scientific name.
Micrathene whitneyi

The Elf Owl is the smallest of all the owls in North America. It’s only 13-15 cm long. It has a wingspan of
38 cm and a very short tail. It has spots of puff or white dapple. This owl has brown plumage and brown streaks on its breast. It has white eyebrows arched above its’ yellow eyes and its’ round head has no ear tufts.
3. Describe the habitat of an elf owl: where do they live? what kind of shelter do they need?
In the Sonoran Desert region, elf owls are found mainly in riparian habitats (places where there is water), or in areas where saguaro cactus are plentiful.
4. How is the elf owl especially equipped to catch its prey?
Elf owls have “silent flight” which means they don’t make any noise as they approach their prey. The sound of their wing beat is muffled by softened feathers on the leading edges of their wings.
5. What do elf owls eat?
They feed primarily on invertebrates such as moths, crickets, scorpions, centipedes and beetles.
6. Describe any “special talents” of the elf owl.
Elf owls will play dead if they are captured or if there is a predator near by.
7. Describe the life cycle of an elf owl.
In the wild, elf owls live 3-6 years. In captivity they usually live longer, between 6-10 years. The female Elf Owl will lay 2 to 4 white eggs. It takes about 24 days to hatch and 28 to 33 days to fledging.
8 . What are some cool “WOW” facts that you learned?
The Elf Owl will spend most its day hiding in a hole or dense leaves. They come out at dusk to hunt. Elf owls are sometimes drawn to campers’ fires, probably for the bugs circling the light. They also eat centipedes, scorpions, and occasionally small birds or lizards. If the owl is threatened, it will usually sit still and camouflage itself in the trees, looking like a broken branch.
Great Gray Owls
1. Strix nebulosa
2.This owl is dark gray with bars and flecks of light gray and white. It has yellow eyes, a long tail and a big head. It has a white mustache and a black bow tie. These owls make about as much noise as other owls but become more vocalized when they are mating and rearing their young.
3. These owls are most common in North America in swamps and forests. During migration they can be found in some fields as well.
4. They locate hidden prey with the help of large facial disks that funnel sound to their ears.
5. It eats small mammals and other small animals.
6. Great Gray Owls are able to plunge with enough force when catching their prey that they can crush a layer of snow strong enough to hold a 180 pound person.
7. Typically when these owls lay eggs they will lay three eggs about two days apart. They will hatch have to 28 to 36 days and will fledge after about 28 days.
8. The most likely place to find them is in Minnesota.
Burrowing Owls
1. Athene cunicularia
2.It is a small ground dwelling bird with a round head and no ear tufts. They have white eyebrows, yellow eyes and long skinny legs. It is sandy colored on the head, back and upper parts of the wing. There is white on the chest and belly. They are easy to see because they are active during the daylight. This owl can make more than 17 different noises. These noised are mostly made during courtship.
3. This is a ground dwelling owl. They need prairie like terrain that has low vegetation, deep soil for burrowing mammals that dig burrows and have a good food supply.
4.
5. They eat insects, small rodents, lizards and birds that they find in the prairie like terrain.
6. These owls are able to eat half of their own body weight each day.
7. Nesting season for this species is from late March and during April. They will lay 6 to 12 eggs. They hatch in about 14 days and the young are able to leave the nest after approximately 44 days.
8. The name curicurlaria is latin for miner, given to the owls because of their ability to burrow into the ground like a miner.
Screech Owls
1. Megascops
2. The Eastern Screech Owl (Otus Asio Linneaus) is one of the varieties of screech owls commonly found in the United States. Like the Western Screech, it is the smallest eared owl at only 8 inches long with a 2-foot wingspan. It typically has 70 feathers per square inch of its body. Depending on where it lives, screech owls are red, brown, or gray. In its Rufous, or red color phase, the Eastern Screech Owl is North America’s only reddish eared owl. Eastern Screech Owls make a whinny or trilling sound. It descends in pitch. Loud calls are made when hunting and soft calls when begging or courting. If they are threatened, they will start to click their beaks.
3. These owls tend to reside in woodlands, deciduous forest, parklands, and lots more. They will also avoid dense forest because Great Horned Owl use that habitat. Eastern Screech Owls roost mainly in natural cavities in large trees including cavities open to the sky during dry weather.
4. Given that these owls are darker colors of browns and red, the screech owl is able to camouflage itself among the trees.
5. These owls mainly eat fish, insects, small birds and mammals.
6. Mother owls will attack animals twice their size to protect their infants.
7. An Eastern Screech Owl lays 3-7 eggs. It takes about twenty-six days for the eggs to be incubated and hatched.
8. They will click their beaks together if they feel threatened.
Snowy Owls
1. Nyctea scandiaca
2. The White Owl that has a rounded head, yellow eyes and black bill. The feet are heavily feathered. A distinctive white Owl, their overall plumage is variably barred or speckled with thin, black, horizontal bars or spots. It is only vocal during nesting season and is rarely heard at any other time.
3. The Snowy Owl lives in the Arctic tundra or open grasslands and fields. They rarely venture into forested areas. During southward movements they appear along lakeshores, marine coastlines, marshes, and even roost on buildings in cities and towns. In the Arctic, they normally roost on pingaluks (rises in the tundra) and breed from low valley floors up to mountain slopes and plateaus over 1,000 meters (3,000 feet) in elevation. When wintering in the Arctic, they frequent wind-swept tundra with little snow or ice accumulation.
4. The Snowy owls are able to camouflage themselves against the ice and snow of the arctic tundra that they inhabit so that their prey does not know they are there.
5. These owls prefer a sit an wait technique of hunting their prey, this means that most of their prey is small mammals and other birds.
6. They will sit and wait for hours for their prey. Females are better at catching prey when hidden with bushes and the like, whilst the male is a better hunter in flight because it is almost solid white.
7. These owls lay 5 to 7 eggs on the ground of the tundra. The females will incubate the owls for about 32 days while males bring the females food.
8. During hot weather, they can thermoregulate by panting and spreading their wings. Snowy Owls are very aggressive when defending their nest.
Great Horned Owls
1. Bubo virginianus
2. This owl has tail feathers that are motted with brown. The throat is pure white with under parts that are barred with black. The tufts or feathers are what gives the owl the “horns.” It has yellow eyes with large feet with big talons. It can either be reddish brown or a grayish color. The owl calls 3 – 8 hoots but most often 6. These hoots are quite deep.
3. The owl is a very adaptable bird and can live in coniferous forest, arid desserts, wooded city parks, trees, caves, cliff ledges and even on the ground. They can be found in cities, residential areas and industrial developments.
4. With their large talons and massive wing size these owls are able to overtake their prey. It can also turn its head 190 degrees and has binocular vision.
5. It can feed on almost anything, including: mice, rats, birds, fish, frogs, lizards, muskrats, large insects, squirrels, cats, rabbits, snakes, small dogs and other owls.
6. It can turn its head 190 degrees.
7. This owl does not build its own nest but will use the nest of other birds. They will raise 2 -4 young owls called owlets. The mother is very protective and after 7 to 10 weeks the owls begin to fly and leave the nesting area.
8. Often called a tiger with wings.
