Three Birds, Three Outcomes

Joel Greenberg and a Passenger Pigeon

San Francisco: Thursday November 20
7 p.m. refreshments, 7:30 p.m. program 

Three different birds, three different outcomes at the hands of humans. The Passenger Pigeon once numbered in the billions, yet human exploitation drove it to extinction a century ago. The Kirtland’s Warbler had dwindled to fewer than 200 singing males in 1971, yet today we know how to maintain healthy populations. The Whooping Crane was down to 23 individuals – twice – and its fate still remains an open question. What can these three birds tell us about how to coexist with other species?

Joel Greenberg is a Research Associate of both the Field Museum and the Chicago Academy of Sciences. He is author of A Feathered River Across the Sky: The Passenger Pigeon’s Flight to Extinction and has been a leader in Project Passenger Pigeon, marking the anniversary of the species’ extinction.


No Speaker Series in December due to the Christmas Bird Count!
