See also: Cultural depictions of ravensThe Common Raven and Carrion Crow have been blamed for killing weak lambs and are often seen eating freshly dead corpses probably killed by other means. The Australian raven has been documented chasing, attacking and seriously injuring lambs. Rooks have been blamed for eating grain in the UK and Brown-necked Raven for raiding date crops in desert countries.
In Auburn, New York (USA), 25,000 to 50,000 American Crows (C. brachyrhynchos) have taken to roosting in the small city's large trees during winter since around 1993. In 2003, a controversial, organized crow hunt proved ineffective at reducing their numbers and the problem (concerns for public health and the sheer noise of so many crows) continues.
At a Technology Entertainment Design conference in March 2008, Joshua Klein presented the potential use of a vending machine for crows. He suggested the crows could be trained to pick up waste and the vending machine would be designed to give a reward in exchange for the trash.
Though humans cannot generally tell individual crows apart, crows have been shown to have the ability to visually recognize individual humans, and to transmit information about "bad" humans by squawking.

Famous quotes containing the words human and/or culture:
“Television was not invented to make human beings vacuous, but is an emanation of their vacuity.”
—Malcolm Muggeridge (1903–1990)
“Here is this vast, savage, howling mother of ours, Nature, lying all around, with such beauty, and such affection for her children, as the leopard; and yet we are so early weaned from her breast to society, to that culture which is exclusively an interaction of man on man,—a sort of breeding in and in, which produces at most a merely English nobility, a civilization destined to have a speedy limit.”
—Henry David Thoreau (1817–1862)
