The whooping crane experiment in the Eastern U.S. is trying something new this fall.
Wildlife officials hope some young birds will migrate south with older cranes instead of
behind ultra light aircraft. The Great Lakes Radio Consortium’s Chuck Quirmbach
reports:


For five years, researchers trying to create a migrating flock of whooping cranes have had
younger birds follow ultra lights for the cranes first trip to Florida, but this year wildlife
officials also trained four young whoopers to associate with older cranes at their summer
nesting area in Wisconsin. The hope is the young birds will migrate with the older ones
and not need a human guide.


Larry Wargowsky manages the Necedah National Wildlife Refuge. He says the effort
called, “Direct Autumn Release,” aims to better mimic nature and save money.


“The ultra light training is very time consuming, very expensive because you have a
group of people that are involved with it from day one all the way through to migration in
the fall, whereas the direct autumn release takes fewer people. You don’t need planes.”


Wargowsky predicts the ultra light aircraft will eventually be phased out of the whooping
crane reintroduction program.

NEW JET ENGINES EMIT MORE NOx

Although commercial airlines have been replacing their fleets with jets that are quieter and more fuel efficient, the engines actually emit more of certain pollutants. The Great Lakes Radio Consortium’s Lester Graham explains:

Although commercial airlines have been replacing their fleets with jets that are quieter and more
fuel efficient, the engines actually emit more of certain pollutants. The Great Lakes Radio
Consortium’s Lester Graham explains:


The federal government’s watchdog agency, the General Accounting Office, issued a report that
finds many airports have worked to reduce air pollution. Some have converted airport ground
vehicles to cleaner burning fuels. Newer jet engines emit less carbon monoxide and
hydrocarbons. But, they produce higher amounts of nitrogen oxides than engines on the older
models. As much as 40-percent more during landings and take offs. Those emissions contribute
to ozone pollution. That’s helping to keep more than half of the nation’s major airports in
violation of the federal ozone standards.


The General Accounting Office noted there are technologies available to limit nitrogen oxides
emissions from some of the newer aircraft models. Many government officials indicate that will
likely have to be the next step if ozone pollution around the airports is to be reduced.
