[Related to this story, CBC Radio News this morning reported that diazinon,
an insecticide, was suspected in the poisonings of the gulls, but this
article only says, "The investigation showed that some insecticide was put
out somewhere on somebodyıs farm. Itıs stuff that they spray in the fields
for the smaller bugs and whatever," said Mr. Melanson.

"We canıt find the source."]

[I believe that diazinon is now banned for use residentially for
lawns/yards, but what about rural applications??][JW]

Poisoning kills hundreds of gulls

By BRIAN MEDEL Yarmouth Bureau

SOUTHVILLE ‹ Dead and dying gulls have been turning up in lakes and along
country roads in a remote part of Digby County since the beginning of May.

The birds were apparently poisoned, preliminary lab results suggest.

Some were still alive when found in a stupefied state, said Tony Melanson, a
wildlife technician with the Natural Resources Department.

"Itıs the first time that itıs happened here," he said Tuesday, adding he
didnıt think the poisoning was deliberate.

But it looks like the potent agricultural chemical Diazinon may be the
culprit, said Mr. Melanson.

As many as 200 birds may have died.

"The investigation showed that some insecticide was put out somewhere on
somebodyıs farm. Itıs stuff that they spray in the fields for the smaller
bugs and whatever," said Mr. Melanson.

"We canıt find the source."

The gulls, either dead or dying, were found on six or more lakes.

"Some were out in Doucetteville just in a small pond . . . there was, like,
18 there," Mr. Melanson said.

"Some of them werenıt even dead yet. They were floating in the water. Some
were on the side of the road. We had to put those ones down. There were just
sitting there. You knew there was something wrong."

But that was just the beginning. "We did find some in Sullivans Lake down on
the (highway) 340. . . . Hilltown and Easton is the main area where they
were." Dead gulls were also found on Bill Lake.

Last week someone called department staff from near Ameros Lake in
Southville, where more dead birds were found on the water.

"We went out with the boat and . . . they were dead from two weeks before
that," said Mr. Melanson.

"We left them right there."

The local volunteer fire department helped clean the lake by tossing the
birds into the woods.

The investigation is continuing, said Mr. Melanson.

About 80 gulls are being stored in a freezer in the department depot near
Digby. Others were sent to labs in Truro, Prince Edward Island and Ontario.

Most of Nova Scotiaıs mink ranches are inland in Digby County, where the
gulls have been found.

Earl Prime, manager of the 340 Ranchers Co-op, said heıs heard little about
the bird die-off and said it is unusual. The co-op is owned by fur ranchers
in the area.

Chemicals used in his industry are not typically put out where birds can get
at them, said Mr. Prime. Such chemicals include cleaning solutions for mink
pens.

And gulls donıt usually present a problem for fur farms, he said.

"Itıs according to ranch management. If you keep your ranch clean and keep
your (waste) buried and composted up you wonıt have a problem with
seagulls," he said.
