What
Do Birds Dream About? Singing, Of Course
Thursday December 17 5:10 PM ET
WASHINGTON (Reuters) - Sleeping
birds are not only dreaming, but probably dreaming about
the songs they sing during the day,
researchers said Thursday.
They said their findings add to
evidence that dreaming helps animals -- including humans --
"rehearse'' things they have learned
to do in the day, and help them perform better the next day.
Biologist Daniel Margoliash
and colleagues at the University of Chicago were studying zebra
finches.
They noticed that when the birds
were asleep, their brains showed a burst of activity in an area
known as the robustus archistratalis
(RA), which is known to be involved in singing.
"One would expect this area to be
quiescent during sleep,'' Margoliash, who published the study
in the journal Science, said in
a statement.
They played recordings of the birds
singing while the birds were awake, asleep and knocked out
with anesthesia. They looked at
the electrical activity in the RA of the birds.
The awake birds showed no response
-- just their normal, oscillating patterns. But the sleeping or
unconscious birds showed strong
bursts of activity from the RA. When they were awakened, the
signals went back to normal.
"This is surprising because the
same neurons that show no response during the day have these
strong responses to the bird's own
song when they are asleep,'' Margoliash said.
"It's possible that songs learned
during the day affect the bursting patterns of the RA at night,
serving to solidify the newly learned
songs in the animal's mind.''

Dying At The Doorsteps Of World's National Parks,Study Says
From: Wildlife
Conservation Society - 6/30/98
Hunting, collisions
with automobiles and trucks, and diseases from domestic
animals are
killing grizzlies, tigers and other large predators at alarming rates
when they
leave the confines of national parks, according to a study by the
Bronx Zoo-based
Wildlife Conservation Society and Cambridge University.
The study
warns that regional populations of these animals may collapse if
such mortality
continues.

MYSTERY DISEASE
IS KILLING BALD EAGLES AND COOTS.
-
From: The
Ornithological Newsletter On-Line - June 1998
-
The disease, which
first appeared in southwest Arkansas, may now be present in North Carolina
and Georgia. This disease, which affects the brain and central nervous
system by creating holes in the myelin layers that insulate the nerve bundles,
killed at least 55 bald eagles at three lakes in southwestern Arkansas
and an unknown number of coots in the winters of 1994 and 1996. No other
birds or mammals have been found to be affected. The cause or source of
the disease remains a mystery. Bacteria, viruses or parasites have been
ruled out. While microscopic evidence suggests that a neurotoxin may be
the cause, tests for natural and man-made toxins that can cause this type
of disease have so far been negative. Please report observations of coots
exhibiting disoriented or uncoordinated behavior such as erratic flying
or impaired ability to swim and dive, or of dead coots or eagles to DR.
