Deanna Dawson, Patuxent Wildlife Research Center

Recording the flight calls of migrating birds as they
pass overhead at night is an exciting new technique
for monitoring migration. Deanna Dawson uses sensitive
but inexpensive microphones and recorders at 30
un-manned sites along mountain ridges in Appalachian
Virginia, West Virginia, and western Maryland to pick
up these vocalizations and store them on memory
drives. Then these recordings are analyzed to reveal
patterns of migration, which in turn can tell us what
pathways are in need of protection from, for instance,
communication towers and wind turbines.

Deanna is a veteran field ornithologist at PWRC, known
for her innovative studies of birds in relation to
their habitats. She will demonstrate the equipment,
data, analysis, and results of her acoustic monitoring program.
