Ericka -- thanks for these articles.

I don't know the date of the articles, but I recently received an alert
about the continuing threat to the red-winged blackbirds (and other birds),
so the article on blackbirds could be from last year.

I think there are about 60 species of other birds that could be impacted by
this poisoning.

Poisonings

Each spring vast flocks of red-winged blackbirds descend on the plains of
South Dakota, gathering among the cattails and reeds in roosts that can be
500,000 strong. Their morning flights create rippling black clouds as the
flocks set off in search of food. Unfortunately, farmers complain that in
the fall the redwings devour a significant amount of the region's sunflower
crop. In Minnesota and the Dakotas, they say, the birds cost them between $4
million and $11 million a year.

George Linz, a biologist with the federal National Wildlife Research Center,
maintains that by reducing redwing breeding populations in South Dakota in
the spring, the agency may limit the damage the birds inflict on the
sunflower crop when they migrate north in the fall.

To that end, Wildlife Services--formerly known as Animal Damage Control--has
poisoned nearly a million redwings since 1994. This year the agency had
intended to kill 2 million redwings by baiting small plots near their roosts
with rice laced with DRC 1339, a poison that causes kidney and heart
damage.

But the program has been halted, at least for this year, thanks in part to
the National Audubon Society's efforts to publicize the issue. For the first
time in six years, a poisoning permit was denied. "The U.S. Department of
Agriculture has not shown that piles of dead blackbirds increase the
farmers' prosperity," says Perry Plumart, a senior policy adviser in
Audubon's Washington, D.C., office. "Is the goal to poison blackbirds just
to poison blackbirds?"

Plumart also warns that the program could poison species that are causing no
problems, and that many of them are on Audubon's watch lists. Kevin Johnson,
an environmental contaminant specialist with the U.S. Fish and Wildlife
Service, adds that any grain eaters, including sparrows and finches, are
susceptible. Linz counters that according to his research, there is very
little danger to nontarget species, in part because many of them do not
migrate to the areas as early as the blackbirds do.

Although this year's poisonings have been stopped, Wildlife Services wants
to poison 2 million birds a year from 2001 through 2004. --Dan Whipple
