Distribution and Habitat
It has a widespread distribution in southern Asia, being native to Nepal, Bangladesh, India, Pakistan, Sri Lanka, Maldives and Laccadive Islands, South West Thailand and coastal southern Iran. It has been introduced to East Africa around Zanzibar (around 1897) and Port Sudan, and arrived in Australia via ship but has up to now been exterminated. Recently it has made its arrival in Europe and has been breeding in the Hook of Holland since 1998. An individual of this species has been present in Cork Harbour on the south coast of Ireland since early September 2010.
In the New World, a small population of House Crows is established in the area around St. Petersburg, Florida.
It is associated with human settlements in all of its range, from small villages to large cities. In Singapore there was a density of 190 birds/km2 in 2001 with efforts to suppress the population in planning.
Due to a human population explosion in the areas it inhabits, this species has also proportionately multiplied. Being an omnivorous scavenger has enabled it to thrive in such circumstances.
The invasive potential for the species is great all over the tropics. This species is able to make use of resources with great flexibility and appears to be associated with humans, and no populations are known to exist independently of humans.

Famous quotes containing the words distribution and/or habitat:
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
“Nature is the mother and the habitat of man, even if sometimes a stepmother and an unfriendly home.”
—John Dewey (1859–1952)
