Purple Martins Return to Roost; Reduced
Speed Limit at Manns Harbor Bridge
martins are beginning to return to their roost at the west end of the
old Manns Harbor bridge. By the end of July the number of birds at the
site is expected to be close to 100,000.
During the roosting season, N.C. Department of Transportation activates
flashing lights and a 20 mph speed limit on the west end of the bridge
at sunrise and sunset. The reduced speed limit, monitored by law
enforcement, allows safe travel for both motorists and birds.
The newer Virginia Dare Memorial Bridge is an alternative route between
Manns Harbor and Roanoke Island during the hours the birds are active.
During this annual natural phenomenon, martins swarm the bridge in
flocks so large they are seen by Doppler radar. Martins who have raised
their young during the spring in colonies managed by humans come here
from as far away as 150 miles. The birds roost at the bridge to protect
their newly fledged young as they prepare for migrating to Brazil in
late summer. After roosting overnight under the bridge, the birds leave
at sunrise to fly over the coastal plan to feed during the day, then
they return at sunset.
The Coastal Carolina Purple Martin Society will conduct educational
experiences at the west end of the bridge and aboard the Crystal Dawn
headboat. Bridge talks will take place at sunset Thursdays and
Saturdays on July 26, July 28, August 2 and August 4. For more

Sunset cruises aboard the Crystal Dawn are set for Thursdays and
Saturdays on July 26, July 28, August 2 and August 4. Tickets are $30

and Manteo at 7 p.m. and returns at approximately 9:30 p.m. Feel free
