Save the date: Monday, Dec. 6. That's when prize-winning nature author Scott Weidensaul will give a free talk, “Against All Odds – Miracles of Bird Migration,” in DeKorte Park, Lyndhurst.

The talk, hosted by N.J. MC and sponsored by the Bergen County Audubon Society, will take place at 7:30 p.m. in the Meadowlands Environment Center auditorium.

Weidensaul is the author of more than two dozen books on natural history, including the Pulitzer Prize-nominated “Living on the Wind,” about bird migration.

His talk will explore the wonder and mechanics of migration, and the simple ways that humans can help at a time when the populations of many migratory birds are in drastic decline.
