Concert in Virginia Beach to Benefit Migratory Songbirds

On Tuesday morning, May 20, Singer-songwriter James Taylor will be available for an hour news conference with the media to talk about his support for conservation of bird habitat on the Eastern Shore, the launch of his U.S. tour and forthcoming album.  He will be at the VIP Club at the Verizon Wireless Virginia Beach Amphitheater.

A portion of the proceeds of the Virginia Beach concert will benefit the Southern Tip Partnership ), a coalition of conservation groups including the Virginia Coastal Zone Management Program, The Nature Conservancy, the Virginia Department of Game and Inland Fisheries, the U.S. Fish and Wildlife Service and the Virginia Department of Conservation and Recreation.

The groups are working together to protect habitat for migratory birds along the Eastern Shore, which has been recognized as a globally important place for migratory songbirds.  (http://www.deq.virginia.gov/coastal/eslandconservation.html

The song birds also need more habitat to survive their trip & Pleasure House Point being 100% open space would certainly help.
