Birds, Bats, and Weather Radar

WASHINGTON, D.C. – For years images of bats and birds that show
up on weather radars have been an annoyance at best. But now,
biologists say this information can give them a treasure trove of
data about the animals they study.

Researchers told the annual meeting of the American Association
for the Advancement of Science on Friday that they can use the
radar information to learn about seasonal changes in feeding and
migration patterns for bats, birds and even insects. And the
20-years of radar data in government archives means they can even
see how animal activity has changed over time.
