MY FAVORITES BIRDS SPECIES
Ohayou min'na ,...
Today I want to share about my favorites birds species. I choose owl species as my favorite.
4. Northern Hawk Owl
6. Northern Saw-Whet Owl
8. Short Eared-Owl
9. Elf Owl
The Elf Owl (Micrathene whitneyi) is a very small owl with a very round head and no ear tufts. Its plumage is light gray and brown. The face often has a reddish brown facial disc with white eyebrows and gray spots on the forehead and wings. The belly is lighter grey to white and the tail is very short and striped. The wings are long, extending to the base of the tail feathers when resting. The feet and talons are covered in feathers and are very small and weak.
10. Snowy Owl
11. Great Gray Owl
The Great Gray Owl (Strix nebulosa) is characteristic of having a puffy head, yellow eyes, and a circular facial discs. It is one of the largest owls in the world and has an extremely long tail. The plumage of this owl is very fluffy and thickly feathered with gray or brown. The face has a white mustache under the facial disc. The feet are completely covered by feathers. The Great Grey Owl is the provincial bird of Manitoba, Canada.
12. Spectacled Owl
Spectacled owls (Pulsatrix perspicillata)are distinctly colored medium-sized owls with dark brown bodies and very white to yellow-ochre colored bellies. They have a white line outlining their chins. Their name comes from the white color surrounding their eyes that resembles eyeglasses, or “spectacles”. Spectacled owl babies have markings that reflect he exact opposite of their parents, with white bodies and dark faces.
14. Spotted Owl
The Western Screech owl (Megascops kennicottii) is a small owl with fluffy, gray or reddish brown plumage that often camouflages the owl when resting in a tree. Their facial discs are gray or reddish brown with black outlining. There are two different phases of adults. The first is the gray phase. Owls that have the gray-phase coloring are very light gray in color if found in the southwest, and will be darker in color and browner if living in the northwest. The facial discs of these owls are off-white with gray-brown. They have vertical stripes, bars and spots on their belly and under their wings, and have barring ont heir wings and tail. The second phase is the red phase, which is a rare bird to spot. It is darker and is more reddish brown or cinnamon in color than gray. He red-phase adult has spotting on its breast.
Owl Species Overview
Too many people lump owls into one category but there are
actually several different species of them. They vary in size & color even
though the overall anatomy of them is very similar. In fact, there are more
than 20 known species of owls and some experts believe that they will be able
to eventually find even more of them. Here is some information about a few of
them to get your started with your own research.
The Great Horned Owl is one that most people are familiar
with. In fact, it is the most common owl in all of North & South America.
They are well known out there due to the fact that they have been able to
easily adapt to a variety of different changing environments. Yet they are also
the ones that are the most difficult to see.
The Great Horned Owl is able to find great hiding places
during the day. They blend in so very well to the surroundings that it is hard
to identify them. Yet at night their mighty calls can be heard for quite a
distance. This is how most people know that they have such species of owls
living around them.
One species that people find interesting to look at is the
Long Eared Owl. It was first identified in 1758 & has held the fascination of
common people & researchers alike every since. They have ears that are three
times longer than most species and that gets them attention. These ears stand
erect too so that they can use them to pick up noise all around them.
1. Barn Owl
The Barn Owl (Tyto alba) is a medium-sized owl & is of 4 species with dark eyes. This owl has light gray on its upper body with
reddish brown & puffs of white feathers. It has gray spotting on its wings & head. The underside is very white. It has a very distinctly
heart-shaped facial disc that is sharply outlined with reddish brown. Its beak
is off-white & the feet are yellowish white with brown. Females often have
more spots than males.
This owl is nocturnal & preys upon small mammals like
voles, gophers, shrews, mice, rats & also bats, frogs & insects. They
use a combination of sight & hearing to detect their prey. Their hearing is
better than their sight & have the sharpest hearing out of any animal
tested. They have asymmetrical (not evenly placed) ear openings, the left one
being higher than the right one. This allows their ears to be more sensitive to
sounds from different directions. They often hunt in open grasslands. The Barn Owl is found on all continents besides Antarctica, including the entirety of
Australia. It resides in areas of open woodland, heaths & moors. They are
also found in open farmland.
These owls participate in a rising & falling courtship
flight that is performed by the male. The male will hover in front of the
female & show her potential nesting sites and offering her food. They nest in
scattered buildings, caves & tree hollows, where the females will lay 3-6
eggs. The majority of individuals of this species of owl only live between 1-2
years of age.
2. Long-Eared Owl
The Long-Eared Owl (Asio otus) is a medium sized
owl with brown & yellowish brown plumage. It has spots, patches & bars of
color over the majority of its body. It doesn’t have long ears, but rather long
tufts of feathers called ear tufts that resemble ears. It has a black bill and
heavily feathered legs & feet. The facial disc is reddish brown to yellowish
brown in color. Females are often darker in color than males. Its feather
assemblage allows it to have noiseless flight & maneuver easily within
densely covered forests.
This owl is nocturnal and is
active mostly at dusk. It is found in Europe, Asia & North America where it
hunts mammals, including voles, deer mice, kangaroo rats, squirrels, bats,
chipmunks, gophers, shrews & many others. When perched, it often disguises
itself to look like a tree branch by spreading its wings and body. It resides
in the woodlands, the edges of forests and riparian zones, among others. In the
winter they roost in more densely covered areas such as a thicket or in caves & are often found roosting communally.
Nesting sites are chosen during courtship behaviors. The
male owl will perform display flights around potential nests & then wait for
a female to then show her interest in a particular nest by hopping around it.
Often nest sites are found in old crow or hawk nests made of sticks that are
well-covered by dense forest & at least 15-30 feet off of the ground. From
mid March to May, an average of 4-5 eggs are laid. Females aggressively guard
their nests. Long-Eared owls can live for up to 10 years. Threats include
threats by humans and death by road kill. Natural enemies include raccoons
invading nests for eggs & young owl babies. Great Horned Owls & Barred Owls can also become threats to this owl.
3. Barred Owl
The Barred owl (Strix varia) is one of 4 species
with dark eyes and is also known as the Hoot owl. It gray-brown in color and is
medium in size. The chest is patterned with horizontal white bars and vertical
bars on the belly. They are of the typical owl family, exhibiting round facial
discs that are white to brown in color with dark brown edging. Males and
females exhibit the same coloring.
This owl is nocturnal. It perches
on a tree branch or something similar while it watches for prey. Their prey is
wide-reaching, and includes mammals like meadow voles, shrews, deer mice, rats,
bats and squirrels, birds, insects like grasshoppers and crickets and also
fish, frogs and snakes. It is an opportunistic feeder and is sometimes seen
feeding hunting just before dark.
Nesting sites often include cavities in trees and abandoned
nests from hawks, squirrels and crows. It is highly vocal, and often can be
heard calling during the day and night. They have a courtship call different
than their usual call. Courting begins in February, and they breed from March
to August. Courting is begun when a male hoots out and a female responds back.
Males display to the female, in a behavior that includes raising and opening
the wings and moving back and forth on a branch. Females usually lay 2-4 white,
round eggs every 2 to 3 days. The male brings food to the female during this
time.
It is found in the majority of North America, and a large
part of the southern territory of Canada in deep, moist forests, wooded swamps
and woodlands that are in close proximity to water sources. Anthropogenic
threats to this owl include shootings and roadkill and natural threats include
the aggressive Great Horned
owl. They are currently expanding to further western habitats. This
expansion raises concern regarding competition for resources with the
endangered Spotted
Owl.
The Northern Hawk Owl (Surnia ulula) is medium in size, with
an off-white colored facial disc with black rim on the edges and white
eyebrows. Their bodies are dark grey to grayish brown with white spots on the
head. They have what appear to be false eyes on the back of their heads and they
have white to off-white spots on their dark grey backs. Their shoulders exhibit
a white banding pattern. They have a very long tail, which helps them maneuver
around the forests in which they hunt.
This owl is diurnal and is
often found perching on treetops or posts that are uncovered.
The female often selects the nesting site, which is often
cavities in tree trunks, abandoned woodpecker holes, and sometimes will use
nests made of sticks from other birds. The female lays eggs in April and May.
Usually between 5 and 13 eggs are laid and incubated by the female.
This owl inhabits Eurasia in Norway, Sweden and Finland,
throughout Siberia extending east to North China. They also inhabit Central Asia
and North America from eastern Alaska and in most of Canada. They live within
boreal coniferous forests
in lowlands (the area at the base of the mountain that is often lower in
elevation) or mountains. They hunt mainly small mammals like voles, and also
frogs and fish and sometimes fast-flying songbirds.
5. Burrowing Owl
The Burrowing owl (Speotyto cunicularia)is a small owl
that is of the typical owl family. It has a round, light brown facial disc. Its
head, back and upper wings are light brown and the breast and belly are
off-white or cream colored and often have darker barring. They have a distinct
white stripe outlining their chins. Males are often lighter in color than the
females. This owl sometimes preens its parents or preens its nest mates.
This owl is active in the daylight, usually at dusk and
dawn. It can often be found perched standing on one foot on a mound of dirt or
on a fence post where it watches for prey. Their prey includes beetles and
grasshoppers, small mammals like mice, rats, rabbits, and squirrels, reptiles,
birds and amphibians. It nests underground in abandoned burrows of mammals in
open, dry grasslands, desert habitats that have burrowing animals and
agricultural lands. In March or April they will lay between 6 and 9 eggs,
incubated by the female. The male will take care of nestlings later on in
development.
These owls are found in the western United States in all
states west of the Mississippi Valley, in Florida, Mexico, Central America and
largely in South America. Their breeding location is western United States,
their permanent locations are in Mexico, Central America and South America ,
and their wintering location is east of Texas into Arkansas, Mississippi and
Louisiana. They are ground-dwelling birds, so their nests are at risk of
invasion from outside predators. This species of owl is slowly declining from
the prairies, and is listed as endangered and threatened. Their predators
include domestic cats and dogs, larger owls, hawks, skunks, ferrets, armadillos
and snakes. Sometimes, while foraging across roads they are killed by vehicles.
Population declines of this species are recently due to habitat loss and
alteration and pesticides used on agricultural land.
The Northern Saw-whet Owl (Aegolius acadicus) is a small owl
with a short tail and a very large head. There are no ear tufts, and they have
very large, yellow eyes. Their facial disc has a lot of white around the eyes
with brown, grey and whitish streaks on the edge. The majority of the head is
brown to grey brown. They have white streaking on their foreheads. Their bodies
are covered in fluffy, brown or red- brown feathers with spots on their backs.
They have streaks of white on their undercarriage. Their legs and feet are
heavily feathered.
They are found permanently on the western part of the United
States and in some of Mexico and the southern portion of Canada, including
Ontario, Southern Quebec, northern New Brunswick, Prince Edward Island, and
Nova Scotia. They migrate south for the winter to areas of central and eastern
United States, including the Atlantic coastline and the Ohio River Valley. They
reside in coniferous and deciduous forests. These areas often have shrubs or
new-growth thickets in which the owls like to make their nests. Nest sites
include abandoned woodpecker cavities in trees. They often breed in swampy
areas and Riparian zones where the female will lay between 3-7 eggs at a time
and fully incubate the eggs. The breeding season is from March to April. The
Northern Saw-Whet Owl is highly migratory, and thus does not always stay with
the same mate from season to season.
The Saw-whet owl hunts at dusk and dawn and preys upon
smaller mammals, including mice, shrews, voles, squirrels, bats, and sometimes
birds, insects and frogs. Interestingly, when mice are plentiful, the Saw-Whet
Owl may kill many at a time and bring them back to a tree cavity or other safe
place to leave through the winter, preserved in the snow, until spring when
they will eat them. Threats to these owls often include predation by
larger owls and hawks and competition with owls and squirrels for nest space.
7. Eurasian Eagle Owl
The Eurasian Eagle owl (Bubo bubo) is the heaviest
owl in the world. Females of this species can reach greater than or equal to
9.25 pounds, which is twice the weight of an adult female snowy owl, the
heaviest owl in North America. The feathers on the upper portion of the owl are
brown to black and yellowish brown. The back and sides of the neck exhibit a
striping pattern, while the head and forehead have heavy freckling. The plumage
on the back has dark patches. The outer portion of the facial disc appears
framed with black-brown spotting. The tail is dark with blackish brown barring.
The assemblage of the feathers allows this owl to have noiseless flight
This owl is found in North Africa, Europe, Asia and the
Middle East in many different habitats. It often lives in coniferous forests
and deserts and including coniferous forests and deserts, and preferably
landscapes with many rocks and open spaces. They nest on cliff edges, in cracks
between rocks and in caves. They are resourceful in that they may use nests
previously occupied by other birds their size. In late winter the female lays
1-4 white eggs, and while incubating, the female is brought food by her mate
They hunt during dusk and dawn, where it preys upon voles
and rates, beetles, deer fawns, rabbits, birds and mice. Occasionally other
smaller owls may also be a part of their diet, as well as snakes and fish.
The Short-eared owl (Asio flammeus) is a medium-sized owl.
It has brown feathers covering its body and dark lines on its chest, belly and
back. Females have darker colored plumage than males. This color pattern is to
blend in to its surroundings. When camouflaging itself does not work, it fakes
death in order to avoid being eaten.
The Short-Eared owl is found in Iceland, the Galapagos
Islands, North and South America and is the only owl native to the archipelago
of Hawaii. It is often found in open grasslands, prairies, estuaries,
agricultural fields, marshes, and the tundra of the alpine and Arctic. This owl
is a migratory bird, moving through high mountainous areas.
This owl hunts at night and dusk and dawn. Its primary
source of prey is small mammals, including voles, mice, shrews, moles, rabbits
and muskrats. When hunting along coastal areas, this owl hunts shorebirds and
seabirds. Sometimes they feed on insects like grasshoppers and caterpillars. It
carries its prey back to the nest in its talons, whereas the majority of other
owls either eats the food on the spot, or carries their prey back to the nest
in their mouths.
Females often lay between 4-14 eggs, depending on their
geographic location (northern locations lay higher numbers of eggs, and
southern locations lay fewer eggs). Threats to this owl include predation by
Bald Eagles, Red-Tailed Hawks and the Snowy Owl. Skunks, dogs, foxes, coyotes,
crows and ravens often invade ground-laying nests and eat the eggs. This high
predation rate leads to decreases in population size. Human-induced pressures
include collisions with planes on the landing strip of the airport, and
vehicles on the road.
The Elf Owl (Micrathene whitneyi) is a very small owl with a very round head and no ear tufts. Its plumage is light gray and brown. The face often has a reddish brown facial disc with white eyebrows and gray spots on the forehead and wings. The belly is lighter grey to white and the tail is very short and striped. The wings are long, extending to the base of the tail feathers when resting. The feet and talons are covered in feathers and are very small and weak.
This owl nests in woodpecker cavities in cacti and deciduous
trees. Often times the woodpecker cavities are not abandoned, thus raising
competition between the owl and woodpecker. They lay 1-5 white eggs in April or
May. During incubation the female may go off to hunt at dusk while the male
incubates the eggs.
The Elf owl is found in Southwest USA to Central Mexico and
Baja California. It inhabits arid deserts with many cacti, riparian woodlands,
tablelands, woody habitats, canyons, plateaus, mountain slopes and deserts with
a high occurrence of giant saguaro cacti. It is a nocturnal bird with bat-like
flight that predates upon small, weak prey like insects, grasshoppers,
caterpillars, cicadas and scorpions. Their diet consists mostly of insects
either that are resting on tree branches or on the ground. They forage for
insects from the ground. Once they have caught the insect, they bring it back
to a tree branch where they tear it apart to eat it. Predators include large
mammals that can reach the cavities of the trees.
The Snowy Owl (Bubo scandiacus) is a large owl
with a rounded head that is of the typical owl family. They have very white
feathers and black spots or bars lining their wings, back and belly, with the
females showing the most marking, and males sometimes showing no marking.
The Snowy owl is the heaviest owl in North America, and has
the second largest wing area among North American owls. Their beak can reach up
to 2 inches long, and their legs and feet are heavily feathered. The Snowy owl
lives in the Arctic tundra on rises, low-valley floors and mountain slopes and
plateaus high in elevation. They also live on open grasslands or agricultural
areas. They are found in North America, reaching from the northern limits of
the United States and throughout the entirety of Canada and also in Siberia
during the winter, and they permanently reside even further north, reaching
into the Arctic regions.
This owl predates upon larger mammals, including snowshoe
hares which they may swallow whole after breaking the neck, fish, lemmings and
voles. They are opportunistic in their feeding and will also eat smaller
mammals like mice, squirrels and prairie dogs. They often learn to enter animal
traps and eat the trapped animal and the bait from the trap.
The Great Gray Owl (Strix nebulosa) is characteristic of having a puffy head, yellow eyes, and a circular facial discs. It is one of the largest owls in the world and has an extremely long tail. The plumage of this owl is very fluffy and thickly feathered with gray or brown. The face has a white mustache under the facial disc. The feet are completely covered by feathers. The Great Grey Owl is the provincial bird of Manitoba, Canada.
This owl is found in Alaska and across Canada, in the
Northern Rocky Mountains, Minnesota, northern Europe and Asia. They live in
forested areas like coniferous and spruce forests. They often breed in conifer
and red fir forests in the Sierra Nevada. They usually hunt and forage in the
late morning and late afternoon in swamps, bogs and areas with scattered trees
and shrubs. This species of owl migrates to estuaries, and mountain meadows,
among others where it can hunt smaller mammals like mice, voles, chipmunks, and
others.
They nest in forests in nests made of sticks that were once
occupied by hawks, ravens or crows, and sometimes on mistletoe shrubs. They
line their nests with needles from trees, deer hair, moss and bark. They lay
2-5 eggs. While eggs are incubating, the male brings food to the female. They
are aggressive over their nests. They can live up to 40 years of age. Threats
include starvation, predation by Great Horned owls and sometimes wolverines and
human-induced death, including shooting, road kill and electrocutions by wires.
Spectacled owls (Pulsatrix perspicillata)are distinctly colored medium-sized owls with dark brown bodies and very white to yellow-ochre colored bellies. They have a white line outlining their chins. Their name comes from the white color surrounding their eyes that resembles eyeglasses, or “spectacles”. Spectacled owl babies have markings that reflect he exact opposite of their parents, with white bodies and dark faces.
This owl is nocturnal and can be seen being active after
dusk until dawn. It preys upon small mammals like mice, possums, skunks,
insects, birds and frogs, among others. They are found in Mexico, Central
America, and South America in dense tropical rainforests, dry forests,
savannahs with trees, plantations and open areas with few trees. They lay 1-2
eggs in nests in tree hollows. This owl is not generally a commonly found owl,
but is more commonly seen in areas like Costa Rica and the Amazon. A major
threat to this owl is habitat loss and forest fragmentation.
13. Great Horned Owl
The Great Horned Owl (Bubo virginianus)is a large owl
that can be reddish brown, grey or black and white in color. Females are often
larger than males. The facial disc is slightly orange. Its breast has a band of
white feathers closer to the face, and its underside is grey with distinctive
dark grey barring. The “horns” referred to in its name are only tufts of
feathers, that are neither horns nor ears. This owl has a curved upper beak
that can reach 1.5 inches long in adults. They have a really long neck, even
though it appears that the neck is only short. They have huge, thick, heavy
feet with big talons that can reach up to 1.5 inches long that are completely
covered in feathers. The tips of the Great Horned Owl’s wings have a separation
of feathers, called slots. These slots help with lift and maneuverability when
moving through forests to hunt.
This owl is found throughout North America and in Central
and South America in dense forests, deserts and plains, and even city parks.
Some may migrate from northern ranges to the southern ranges of North America.
This owl is known to become aggressive when threatened. They begin nesting in
January or February in the old nest of a crow or hawk, and sometimes a hollow
tree. They lay 2-4 eggs that the female incubate and are protective of their
young to the point of attack.
The Great Horned owl usually begins hunting at dusk, where
it can find voles, mice, rabbits, skunks, house cats, insects, small birds,
pheasants and grouse as prey. In Canada, the Great Horned owl often predates on
the snowshoe hare, which can reach approximately 3 pounds in weight!
The Spotted owl (Strix occidentalis) is one of 4
species of owls with dark eyes. The owl’s plumage is soft and fluffy and brown
with heavy white spotting on the breast and belly. The wings, back and head
have less spots than on the body. Their facial discs are light brown and have
dark brown rings. They have lighter colored eyebrows and bills and feathered
legs and talons.
This owl is found in North America in the western portions
of California, Washington and Oregon, in Alaska, British Columbia, and also in
southern Utah, Colorado, Arizona and New Mexico in the Rocky Mountain region.
It is also found in parts of Mexico. It nests in dense, dark, mature coniferous
forests. They like to live in areas along river valleys with steep walls and
live in forests that have either a lot of fir trees or hardwood trees like
Douglas firs or sycamores. This owl mates for life, and does not breed every
year. It breeds from March to September where it will lay 2-3 eggs.
Threats to this owl include competition for habitat with the
Barred owl, Great Horned owls that prey on adults and young, red-tailed hawks
and ravens. Since their habitat is largely old-growth coniferous forests, it
has been listed as endangered because of the forestry industry that relies on
such forests. This species of owl is important in the Haida cultures of Alaska
and British Colombia. The owl can be seen carved into their totem poles.
15. Western Screech Owl
The Western Screech owl (Megascops kennicottii) is a small owl with fluffy, gray or reddish brown plumage that often camouflages the owl when resting in a tree. Their facial discs are gray or reddish brown with black outlining. There are two different phases of adults. The first is the gray phase. Owls that have the gray-phase coloring are very light gray in color if found in the southwest, and will be darker in color and browner if living in the northwest. The facial discs of these owls are off-white with gray-brown. They have vertical stripes, bars and spots on their belly and under their wings, and have barring ont heir wings and tail. The second phase is the red phase, which is a rare bird to spot. It is darker and is more reddish brown or cinnamon in color than gray. He red-phase adult has spotting on its breast.
This owl is nocturnal, and is seen feeding in the woodlands
of western North America, specifically in the Pacific northwest and dry
southwest. Its distribution ranges from southeastern Alaska, southern British
Columbia, western United States and south through Baja California and parts of
Mexico. It lives in red cedar, hemlock and Douglas fir forests, and also Sitka
spruce forests near bodies of water and riparian woodlands. It prays upon small
rodents and deer mice, insects, small birds, shrews, kangaroo rats and others
in open woodlands where open fields or wetlands are plentiful. This owl nests
in tree cavities found naturally in deciduous trees like oaks, maples and will
use abandoned Pileated Woodpecker cavities as well. During mating season, the
owls will call to each other and are often see preening each other’s heads and
beaks. The female will lay between 3-4 eggs.
Threats to this owl include Great Horned owls, Barred owls,
Long-Eared owls, raccoons, squirrels and snakes, among others. Due to their
preferred habitat locations around riparian areas, much of their habitat is
being threatened by tree removal. They are adaptable in that they can live in
city parks if necessary.
