Rob Bierregaard began researching osprey on Martha’s Vineyard in 1969. Since then, he has been investigating the habits and migrations of these birds on Martha’s Vineyard and beyond. His work and knowledge about ospreys is immense and he will share his passion at a free lecture at the Howes House in West Tisbury on Friday, July 30, at 7 p.m.

Since June 2000, in collaboration with Dr. Mark Martell of the Raptor Center at the University of Minnesota, Mr. Bierregaard has put satellite transmitters on more than 30 adult and juvenile birds on Martha’s Vineyard and at sites along the East Coast. He has followed their movements and migrations; the stories of their travels will astound.

This lecture is free to all. For details, call Felix Neck Wildlife Sanctuary at 508-627-4850. For more information on Mr. Bierregaard and his work, see online bioweb.uncc.edu/bierregaard/.
