Iranian Owl
The Long-eared Owl (Asio otus) is a species of owl which
breeds in Europe, Asia, and North America. This species is a part of the larger
grouping of owls known as typical owls of Strigidae family which contains most species
of owl. The other grouping of owls are the barn owls, family Tytonidae. The Long-eared Owl is a medium sized owl,
31-37 cm in length with an 86-98 cm wingspan. It has erect blackish ear-tufts,
which are positioned in the center of the head. The female is larger in size
and darker in colouration than the male. The Long-eared Owl’s brownish feathers
are vertically streaked. Tarsus and toes are entirely feathered. Its habitat is forest close to open country. It
nests in trees, often coniferous, using the old stick nests of other birds such
as crows, ravens and magpies and various hawks.
An unusual characteristic of this species is its communal nesting in
thickets during the winter months. The Long-eared Owl hunts over open country
by night. It is very long winged, like the similar Short-eared Owl, and glides
slowly on stiff wings when hunting. Its food is mainly rodents, small mammals,
and birds.
Little Owl (Athene noctua) breeding habitat in Iran is
usually in old seasonal river banks in rocky semi-deserts and deserts of Iran.
one of the fascinating places to watch many of them breeding in extreme eastern
steppes of Iran around Birjand Province. Little owl often sits in the
open in day time around the nest and if agitated, often bobs in an upright
posture.
The
Brown Fish Owl (Bubo zeylonensis or Ketupa zeylonensis) is an owl. This species
is a part of the family known as typical owls,
Strigidae, which contains most living owls. It inhabits the warm subtropical
and humid
tropical
parts of continental Asia
and some offshore islands.The four fish owls were previously generally
separated in the genus
Ketupa.

data is equivocal on which genus name is applied for them, and today they are
commonly lumped with the horned and eagle-owls (Bubo)
– which they also resemble osteologically very much – for sake of
convenience. Depending on whether some little-studied tropical eagle-owls are
closer to the fish-owls than to the typical eagle-owls, Ketupa might be a valid
genus if these as well as the fishing owls (formerly Scotopelia) are included
in it. It is a large owl
with prominent "ear" tufts, typically around 55 centimetres
(22 in) in length and weighing 2–2.5 kilograms (4.4–5.5 lb) when fully
grown. Subspecies
differ in size and males are smaller than females, with the smallest birds not
quite 50 cm (20 in) long and weighing as little as 1,100 grams
(39 oz). The upperparts are reddish brown and heavily streaked with black
or dark brown. The underparts are buff to whitish, with dark streaks and finer
brown barring. The throat is white and can be conspicuously puffed, while the
facial disk is indistinct. The irides
are yellow, the feet a duller yellow, and the bill is dark. Sexes do not differ
in appearance except for size.
The
Spotted Owlet (Athene brama) is a small owl which breeds in
tropical Asia
from India
to Southeast Asia.
A common resident of open habitats including farmland and human habitation, it
has adapted to living in cities. They roost in small groups in the hollows of
trees or in cavities in rocks or buildings. It nests in a hole in a tree or
building, laying 3-5 eggs. The species is absent from Sri Lanka, although the
birds are found across the Palk Straits, just 30 kilometres away at Rameshwaram.
Nests near human habitations may show higher breeding success due to increased
availability of rodents for feeding young. The species shows a lot of variation
including clinal variation in size and forms a superspecies with the very
similar Little Owl.
The Spotted Owlet is small (21 cm) and stocky. The
upperparts are grey-brown, heavily spotted with white. The underparts are
white, streaked with brown. The facial disc is pale and the iris is yellow.
There is a white neckband and supercilium. Sexes are similar. The flight is
deeply undulating. The nominate form is darker than the paler forms such as indica
of drier regions.
The Eagle Owl (Bubo bubo) is a large and powerful owl in
Iran. Iran also hosts Ascalaphus sub specie of eagle owls. The other sub specie
known as desertorum lives in arid regions of Arabia. In Iran we should be able
to observe two different variants of eagle owl; One being common eagle owl and
the other being Ascalaphus SS. The Ascalaphus is known to be 20% smaller and
has paler underparts blending to less spoted and blotched markings. In compare
with eagles, smaller than the Golden Eagle but larger than the Snowy Owl. Snowy
owl is hardly seen in Iran only random reports of them wintering in NE Iran.
Eagle owl is titled the Iran's largest owl. The photo on the right is
Ascalaphus SS of eagle owl (Bubo ascalaphus) which is resident in Iran. The Eagle Owl has a wingspan of up to 138-200
cm and measures 58-75 cm long. Females weigh 1.75-4.2 kg and males weigh
1.5-3.2 kg. It mainly feeds on small mammals, but can kill prey up to the size
of foxes, Jackals and young deer (up to 10 kg/22 lb), if taken by surprise.

Fur or feather eagle owls are savvy night hunters. Larger prey is consumed on
the ground which leaves the bird vulnerable to ground hunters like wolves. The
call of the Eagle Owl is a deep resonant “ooh-hu” with emphasis on the first
syllable for the male, and a more high-pitched uh-Hu for the female (in German,
the name of this bird is "Uhu"). Each member of an Eagle Owl
population can be identified by means of its vocalizations. The size, ear tufts
and orange eyes make this a distinctive species. It has a strong direct flight.
The ear tufts of males are more upright than those of females.
The horned owls are a part of the larger grouping of owls
known as the typical owls, Strigidae, which contains most species of owl. The
other grouping is the barn owls, Tytonidae.
The Pallid Scops Owl (Otus brucei) is a small Scops Owl
ranging from the Middle East to West and Central Asia, sometimes called the Striated
Scops Owl.

The Pallid Scops Owl is a small eared owl similar in appearance
to the Common Scops Owl but with more distinct streaks
on the back and less intricate markings.The Pallid Scops Owl ranges from the Middle East
to West and Central Asia,
with some populations moving as far as the Arabian Peninsula, Egypt,
and Pakistan in the winter. It inhabits semi-open country with trees and bushes
and has an estimated range of one to ten million kilometers. This species has
an extremely large range, and hence does not approach the thresholds for
Vulnerable under the range size criterion (Extent of Occurrence <20 a="a" and="and" appears="appears" approach="approach" be="be" combined="combined" criterion="criterion" declining="declining" does="does" extent="extent" fluctuating="fluctuating" for="for" fragmentation="fragmentation" habitat="habitat" hence="hence" km2="km2" locations="locations" not="not" number="number" of="of" or="or" population="population" quality="quality" range="range" severe="severe" size="size" small="small" species="species" stable="stable" the="the" thresholds="thresholds" to="to" trend="trend" under="under" vulnerable="vulnerable" with="with">30%
