The document describes several species of crows: - The house crow is common in many parts of the world due to shipping, between the sizes of a jackdaw and carrion crow with a black forehead/crown and grey-brown neck and breast. - The carrion crow is native to western Europe and eastern Asia. - The large-billed crow has a large bill and is very adaptable, allowing it to colonize new areas. It is sometimes known as the thick-billed crow. - The eastern jungle crow is found in parts of Asia. - The Indian jungle crow is found across the Indian subcontinent and can be difficult to distinguish from other crow species, having

1. House Crow
The house crow (Corvus splendens), also
known as the Indian, greynecked,
Ceylon or Colombo crow,[2] is a
common bird of the crow family that is
of Asian origin but now found in many parts
of the world, where they arrived assisted by
shipping. It is between the jackdaw and
the carrion crow in size (40 cm (16 in) in
length) but is slimmer than either. The
forehead, crown, throat and upper breast are
a richly glossed black, whilst the neck and
breast are a lighter grey-brown in colour. The
wings, tail and legs are black. There are
regional variations in the thickness of the bill
and the depth of colour in areas of the
plumage.

2. Carrion Crow
The carrion crow (Corvus
corone) is a passerine bird of
the family Corvidae and the
genus Corvus which is native
to western Europe and
eastern Asia.

3. Large Billed Crow
The large-billed crow (Corvus
macrorhynchos), is a
widespread Asian species of crow. It is very
adaptable and is able to survive on a wide
range of food sources, making it capable of
colonizing new areas, due to which it is often
considered a nuisance, especially on islands.
It has a large bill which is the source of its
scientific name macrorhynchos (Ancient
Greek for "large beak"), and it is sometimes
known by the common name thick-billed
crow. It can also be mistaken for
a raven. Johann Georg Wagler first described
the species from a holotypeobtained from
Java in the year 1827.[2] The eastern jungle
crow and Indian jungle crow were considered
conspecific, and together called jungle crow

4. Eastern Jungle Crow
The eastern jungle
crow (Corvus levaillantii) is a
bird in the family Corvidae. It
is found
in China, Bangladesh, India, M
yanmar, Nepal, Bhutan,
and Thailand.

5. Indian Jungle Crow
The Indian jungle crow (Corvus culminatus) is a
species of crow found across the Indian
Subcontinent south of the Himalayas. It is very
common and readily distinguished from
the house crow which has a grey neck. In the
past the species was treated as a subspecies of
an other crow species but vocalizations and
evidence from ectoparasite co-evolution and
phylogenetic evidence have led to it being
considered as a distinct species in modern
taxonomic treatments. It differs in its voice from
the large-billed crow found in the higher
elevations of the Himalayas and the eastern
jungle crow (Corvus levaillantii) overlaps in the
eastern part of its range. In appearance it can be
difficult to distinguish from either of these
species although the plumage tends to be more
uniformly glossed in purple and has a longer bill
with a fine tip and an arched culmen. The
Himalayan species has a slightly wedge-shaped
tailunlike the rounded tail of the Indian jungle
crow and tends to glide a lot .
