Open air sports stadiums often have issues with birds
, and other wildlife. Common preventative measures include ultrasonic devices
and bird netting
. But Nelson Mandela Bay Stadium - one of the venues for the 2010 World Cup - has taken an all-natural approach. It is working with the Urban Raptor Project to install raptors
, bats, and owls to patrol the stadium
for various pests, while a trained peregrine falcon
chases away crows. This is not a new technique - Millennium Stadium
in Wales has long used a Harris Hawk
for bird control. But according to the NMB stadium manager, it "is the only stadium with a programme like this in place as a pest deterrent".

Long revered for its value as a fertilizer
, and as a raw material for explosives
, guano is the dried droppings of various birds and bats. The New York Times has published an excellent account of the Peruvian harvest
of this valuable resource including a multimedia slideshow
. Guano was superseded by synthetics in the early part of the 20th century, due to the development of the Haber Bosch process
, which fixed atmospheric nitrogen
An attempt to harvest bat guano from a Grand Canyon cave
in the late 1950’s was beset by technical problems and was ultimately unsuccessful. The remaining structures at the canyon rim are now a tourist attraction.

Barry Bonds has broken the all-time record with the benefit of a controversial
technological revolution in the game, derided by traditionalists:
The Maple Baseball Bat.
Using technology and woodworking techniques pioneered by Sam Bat,
Bonds helped develop and popularize the bats that are just as responsible for the advent of the Juiced Ball Era
as, well, the other thing.
