From ANIMAL PEOPLE, March 2006:
DARIEN (Ct.), SAN FRANCISCO –Crows and parrots, believed
to represent the apex of avian intelligence, evolved in an
environment favoring agility and efficiency in the lightest possible
package.
Any air war strategist could therefore predict the outcome in
conflict between the bird brains and exterminators with thoughts of
lead.
Foes of crows with shotguns, fireworks, lasers, and
recorded distress calls took the most murderous toll on crows they
could during the winter of 2005-2006, on battlefields from upstate
New York and the Philadelphia suburbs to the Rocky Mountains.
Most of the crows, however, are still there, or at least
not very far away.
Attempted parrot purges have been no more successful, even
though the entire U.S. wild parrot population is believed to be
probably about 20,000, not more than 50,000 by the highest serious
estimates. About 7,000 parrots, mostly monk parakeets and conures,
live in California, with at least 2,000 monk parakeets in Florida.
USDA Wildlife Services claimed in January that a week of
nonlethal hazing had driven all but 500 crows out of Auburn, New
York, where as many as 33,000 congregated a few weeks earlier.
Complaints about crows meanwhile erupted in Syracuse, Marcellus,
Cazenovia, and Cortland, noted Syracuse Post-Standard staff writer
John Stith.
