Introduced Birds
An introduced, alien, exotic, non-indigenous, or non-native species, or simply an introduction, is a species living outside its native distributional range, which has arrived there by human activity, either deliberate or accidental. Some introduced species are damaging to the ecosystem they are introduced into, others have no negative effect and can, in fact, be beneficial as an alternative to pesticides in agriculture for example. In some instances the potential for being beneficial or detrimental in the long run remains unknown, for instance in New Zealand. A list of introduced species is given in a separate article.
The effect of introduced species on natural environments is a controversial subject, and one that has gained much scrutiny by scientists, governments, farmers and others. Not all introduced species are problematic. Those species that spread widely and create significant problems are known as invasive species.

Famous quotes containing the words introduced and/or birds:
“... it was not very unusual at Washington for a lady to take the arm of a gentleman, who was neither her husband, her father, nor her brother. This remarkable relaxation of American decorum has been probably introduced by the foreign legations.”
—Frances Trollope (1780–1863)
“Even Lust the Master of a hardned Face,
Blushes if thou beest in the place,
To darkness’ Curtains he retires,
In Sympathizing Night he rowls his smoaky Fires.
When, Goddess, thou liftst up thy wakened Head,
Out of the Mornings purple bed,
Thy Quire of Birds about thee play,
And all the joyful world salutes the rising day.”
—Abraham Cowley (1618–1667)
